StableLoad Challenge is back again: What’s the point of 4-point suspension?

If you’ve seen our first go at the StableLoad Challenge, it’s clear that those who tested the StableLoad suspension stabilizer are convinced on its ability to remedy handling issues of a loaded down truck. In hopes of echoing this approval, we took the StableLoad Challenge to Everett, Washington.

What’s the StableLoad Challenge?

Could they tell the difference?

When we rolled on up to Everett from our manufacturing facility in Sumner, Wa., we were excited to introduce the StableLoad Challenge to Torklift dealers attending a dealer training session for Torklift products. Take a look at what these folks had to say about their experience:


How was the StableLoad suspension stabilizer so successful in solving side-to-side sway, body roll and other tedious handling characteristics caused by hauling heavy loads or towing trailers?  

Let’s take a look at how suspension works on your vehicle.

Originally, vehicles are designed and built with four-point suspension.  Each of the two rear leaf springs has two points of suspension on each end of the leaf spring giving you four total points of control.

4-point-diagramVehicle manufacturers create a
4-point leaf spring suspension system
on the vehicle’s rear axle
Your vehicle’s factory engineers invest millions of dollars to ensure a four-point suspension system because it provides a needed compromise between your ride quality while towing/hauling and also the ride quality while driving unloaded.

Other suspension products diminish the factory four-point suspension and reduce the control points to only two. For example, airbags take all of the weight that you are applying to the truck by lifting it above the leaf springs. By placing weight onto just two airbags, you may have successfully leveled your ride but unintentionally created issues with side-to-side sway and bounce.

Other aftermarket suspension products create the opposite effect of the control that 4-point suspension provides.  Two-point suspension provides only minimum control. Just like two heads are better than one, four points are better than two. Simple concept, yet a mind blowing difference.

Teaming up with your factory suspension
teamworkStableLoads are the only suspension upgrade that works with your factory suspension and continues to use all four points of the suspension. By pre-engaging the vehicles already existing factory installed overload leaf springs, the vehicle is prepared in advance for the effects of heavy payload caused by towing and hauling. Using precision laser-crafted wedge plates, the lower StableLoad application eliminates the gap between spring pack and lower overload leaf springs.

Translation? The truck isn’t required to drop several inches from the weight of the load in order to initiate the support needed from its overload leaf springs. By maintaining the four-points of contact, the suspension is being used with the maximum potential in which its factory engineers intended.giftThere are benefits to working with factory suspension

Teaming up comes with benefits
Trucks are expensive. You pay a lot to have comfortable ride quality and when you load your truck down, you’ll say sayonara to that once enjoyable ride. If your expensive truck rides like a dream, would you want to modify it to ride like dad’s old ‘76? Meh. We think not.


switching-on-modeTurning the StableLoads on is simpleWith the lower StableLoads ability to be turned on and off, you can change the settings of your vehicle. When towing or hauling, simply turn on the StableLoads to engage the suspension sooner giving you a stable ride and dramatically reduced side-to-side sway, body roll and porpoising. StableLoads allow you to have the stiffer/towing ride when you need it, and the smooth factory ride when you don't.

Why choose StableLoads over Airbags?
As previously noted, airbags provide only two points of contact on your factory suspension as opposed to the original four points. Airbags take the weight of the towing or hauling load off of your suspension and essentially redistributes it onto two balloons. This causes a teeter-tottering effect. With airbags, the weight can shift back and forth causing your factory suspension to become disengaged. Click here to learn how airbags affect your suspension.

Backed by Science
We’ve heard thousands of success stories from those who’ve turned to StableLoads instead of other suspension products. Even with real-life feedback from those who took the StableLoad Challenge, we wanted to provide factual data based on actual side-by-side comparisons between Stableloads and other suspension products. By using precise motion measuring devices, we’ve discovered significant scientific information that strongly supports the glowing testimonials from our happy customers. Click here to see the science behind the StableLoads and you’ll be shocked at what we revealed with our experiment. 

The StableLoad suspension stabilizer is easy to install and applicable to any truck, van, SUV or small commercial vehicles with factory overload leaf springs. Find your application or click here to learn more about Torklift StableLoads.

Add-on leaf springs or airbags? StableLoad Challenge reveals the best solution for suspension

b2ap3_thumbnail_engagedstableload.jpgStableLoad suspension upgrade turned on

Torklift International StableLoad suspension stabilizer is a simple but highly effective product that installs on any truck, van, SUV or small commercial vehicle with factory overload leaf springs. StableLoads allow the vehicle to handle payload more effectively because the factory overload leaf springs are initiated.

By inserting precision-crafted wedge plates into the gap between your vehicle’s leaf spring pack and lower overload leaf spring, the factory leaf springs activate and perform to their full potential. Click here for details on how leaf spring suspension works.

When a vehicle’s supporting extra load, the driver often experiences poor handling characteristics such as body roll, side-to-side sway and porpoising. Driving under these conditions is not only uncomfortable, but also unsafe. When StableLoads are turned on, experience a smoother ride that’s safe and worry-free.

At a recent rally, Torklift International introduced the StableLoad Challenge to attendees. As people who tow trailers or haul truck campers often, we thought who better to experience how the StableLoads affect a vehicles suspension.

lance-camper-rallyAttendees of the Lance Owners of America Rally in Acton, Calif.

poundsTo introduce the StableLoad suspension upgrade to rally-goers, the StableLoad Challenge required two identical Ford F150 trucks loaded with a 2,800-pound load to simulate a truck camper or trailer.

What was the difference between the Ford trucks? One Ford F150 truck had StableLoads installed, the other Ford F150 truck used only its factory suspension. Test-drivers drove both Ford trucks with and without the StableLoads to see if they could feel the difference in handling.

Take a look at this unseen footage of Randy Risso’s test-drive:

Without the StableLoads, Randy mentions he could feel the 2,800-pound load in the bed leading the truck as opposed to having controlled steering ability. He also discusses alternative suspension upgrades as he currently has airbags installed on his truck to haul his Lance truck camper.

randyRandy has thought about add-on leaf springs to help carry his truck camper more effectively. However, negative side effects that extra add-on leaf springs place on his truck’s ride quality has convinced him otherwise. Since his Lance truck camper isn’t always loaded on the truck, he doesn’t want to be stuck with a stiff ride when the vehicle is unloaded.

When Randy drove the F150 truck with the StableLoads turned on, he could easily tell the difference with how the Ford truck handled.

“It’s almost like not having any load at all!” Risso said.

Unlike any other aftermarket suspension upgrade available, the StableLoads are easily switched on and off, leaving you to enjoy your smooth factory ride when unloaded but also activating extra support when towing or hauling is necessary.

The lower quick-disconnect StableLoads engage and disengage in seconds.

Engaging StableLoad Suspension Stabilizer

balloonsAirbags can be like balancing your payload on two balloonsRandy talks about the combination of StableLoads and airbags. Although airbags are effective with leveling a vehicle under load, they often cause negative side effects of increased side-to-side sway, stiff ride quality and potential for leaks.  By lifting payload completely off the vehicle’s leaf springs, the entire load is balancing on an area roughly the size of two balloons. The stabilizing effects and power of the vehicle’s factory suspension essentially go untapped.  

Be sure to read our article on 3 easy steps to eliminate bounce and sway from airbags.  By decreasing the air pressure in airbags and engaging the leaf springs with StableLoads, you’ll find that all core issues with poor handling are addressed. Several people turn to StableLoads prior to installing airbags on their vehicle. Typically no further aftermarket suspension mods are needed due to the effectiveness of Torklift StableLoads.  

Overall, rally-goers that took the StableLoad Challenge were impressed with the improvement in ride quality that the StableLoads provided.

Three most common handling issues when towing or hauling

To help reduce poor handling and enhance the suspension of a vehicle, it’s proven that the StableLoad suspension stabilizer not only significantly improves all aspects of ride quality, but also provides overall safer experience on the road.

b2ap3_thumbnail_SL_Product_Box_OU.pngStableLoad suspension upgradeWe’ll take a look at the most common complaints of poor handling experienced when hauling a truck camper or towing a trailer to show why StableLoads are the first suspension modification you should turn to.  StableLoads engage and activate the stabilizing effects of your vehicles factory overload leaf springs, providing the support needed to handle extra weight.

StableLoads easily install on any vehicle including trucks, vans, SUV’s and light commercial vehicles that come equipped with factory overload leaf springs.

To put the capabilities of the StableLoad suspension stabilizer to the test, let’s examine real life experiences of people who tow or haul often.

Cue the StableLoad Challenge: an opportunity to see if others noticed improvement in ride quality from driving a Ford F-150 truck both with and without the StableLoad suspension stabilizer.  bruceThe challenge allowed attendees at a rally to experience the Ford F-150 truck’s suspension with a 2,800-pound load in the back.

Rally-goer Bruce Pound took the challenge to learn more about the capabilities of the StableLoad. During his test-drive with the StableLoad suspension stabilizer turned on, he mentioned how the StableLoads make a difference when it comes to the three most common handling problems.

Issue #1: Side-to-side Swayside-to-sideSide-to-side sway
When a vehicle is under significant load, the suspension is unable to provide proper support causing the truck to sway from side-to-side. As a typical complaint from those who haul campers, the camper creates a “top-heavy” feeling and it’s difficult to gain control of the vehicle, especially at higher speeds.

“I can tell a difference in the suspension itself,” said Pound. “You don’t feel as if you’re swaying -- the side-to-side sway isn’t there.”

To aid suspension and level the vehicle, many people turn to airbags. However, the side effects of installing airbags will actually increase side-to-side sway and amplify bounce motion. With airbags payload is balanced on an area roughly the size of two footballs, lifting the weight completely off the factory suspension, taking the truck’s factory spring suspension completely out of use. StableLoads put your suspension back into effect and work with factory overload leaf springs to trigger exactly what they’re built for.

Issue #2: PorpoisingporpoiseBounce and porpoising
Misalignment increases stopping distance, ability to steer without delayed response, increased tire wear and more negative characteristics. This results in the front and back motion known as ‘porpoising.’ A heavy load in the back of your vehicle tends to put additional weight on the rear axle, causing the truck to sag and the nose of the vehicle to tilt upwards. This unnatural positioning impacts the drivability and handling of the vehicle, causing forward and backward rocking.

The first thing that Bruce Pound noticed during his test-drive was the aspect of braking more effectively.  The distance needed to stop the truck was noticeably less and the porpoising effect when trying to stop the vehicle was completely eliminated.

“With the StableLoads the braking feels a lot smoother,” said Pound. “When I hit the brakes with that one [Ford F150 without the StableLoads], there was a lot of rocking.”

Issue #3: Body RollbodyrollVehicle body roll
When maneuvering winding roads and sharp corners, a vehicle carrying added payload is much harder to control. Vehicles with high center of gravity like truck campers or higher ground clearance are notorious for pitching and leaning over each side when turning.  

When cornering during the test-drive, body roll of the vehicle was significantly reduced.

 “There is a definite difference,” said Pound. “This was a much smoother ride.”

As the load transfers toward the outside of turns, StableLoads allow you to keep control of the vehicle’s direction by increasing stability.

One solution solves all three of these common handling issues, plus additional benefits.  The StableLoads also help by leveling the vehicle and eliminating sag, which can cause serious side effects not only to your ride quality, but the truck itself.

Torklift International StableLoad suspension stabilizer is the only suspension modification that can be adjusted for use. With the ability to literally turn the StableLoads on and off by engaging and disengaging them in seconds, enjoy the convenience of returning to your comfortable factory ride when you’re not towing or hauling.

Deception is a matter of perception

stableloads-reviewPerception of the StableLoad Suspension Stabilizer

What do you see? #BlackandBlue or #WhiteAndGold?the-dressThe Dress

Is this an instance of deception or a matter of perception? If you haven’t heard of #TheDress that sparked an internet-wide debate in late February 2015, it is an ideal example of countless accounts of the varying perceptions of its viewers.

Asked to identify the color of a dress, which appeared to be white and gold or black and blue, the simple question prompted discussions and arguments across the web. Even though the dress was confirmed to be blue and black, scientific commentary was centered on the photo as an optical illusion. If you missed this phenomenon that absolutely rocked the internet, click here for details.  

Instead of #TheDress, let’s take a look at the StableLoad suspension upgrade. Regardless of comparison to other suspension products, the stabilizing effects of Torklift International StableLoads remain true and constant.  

Watch this video that compares StableLoads to all aftermarket suspension modifications including airbags, add-on leaf springs, sway bars and shocks:

What are the benefits and potential negative side effects of each suspension modification?

Torklift StableLoad vs. other products

Sway Bars and Add-on Leaf Springs
The purpose of sway bars is to make a connection between the truck frame and its axles with a spring steel bar, reducing sway and body roll. Add-on leaf springs help to increase the spring rate of your factory springs to eliminate sag and sway. Although both of these alternatives maybe effective in eliminating sway, the side effects result in a much harsher ride due to the stiffened suspension.

Airbags and Shocks

Additional aftermarket suspension upgrade options include shocks and airbags.
Shocks act as a dampener by resisting movement between the body and axle to help eliminate body roll. Airbags inflate with air pressure to lift the truck frame away from the axle and help level the truck. A side effect of shocks and airbags lies within the potential for leaks. Not only do both significantly stiffen your ride, airbags will often increase side-to-side sway of the vehicle because it takes the weight off of the factory suspension.b2ap3_thumbnail_stableload-display.pngStableLoads engaged and disengaged

StableLoad Suspension Stabilizer

The StableLoads combine all of the benefits of all these products but without any negative side effects.  StableLoads are proven to be a successful solution to aid your vehicle in handling its payload in a more safe and effective manner. Click here to see how StableLoads affect your leaf springs.

Increasing Payload Capacity
It’s often misunderstood that adding suspension upgrades to your vehicle increases your vehicle’s factory towing or hauling capacity. No suspension upgrade can increase your truck’s maximum vehicle manufacturer assigned capacity ratings.

PinocchioPinocchio “I will not tell a lie”

A deceptive claim is an implication that a suspension modification could successfully add weight or load carrying capacity to your vehicle. The weight ratings for your vehicle are absolute. Manufacturers set these limits in order to keep you safe from failure of vehicle parts.

Perception not Deception
It’s expected for people to have varying opinions based on their personal experiences. We encourage discussion on topics such as payload capacity and suspension modifications for towing or hauling as sharing ideas is the best way to learn about something new to you. Online forums like are useful tools to learn from others with similar interests.

3 easy steps to eliminating the bounce and sway from airbags

When loading up a truck with something heavy like a truck camper, our first instinct is to level the vehicle. The weight on the rear axle causes the truck to sag and tilts the nose of the vehicle up. Driving a truck in this position can be dangerous because it takes control away from the driver.

Even though there is a leveling benefit from airbags, this suspension modification can have some negative side effects. Instead of activating the factory suspension like the StableLoad suspension stabilizer, airbags change the entire dynamic of your suspension by lifting the weight off of your overload springs.

The side effects you feel from airbags include an increase in side-to-side sway and amplified bounce motion when hitting a bump in the road. This is happening because airbags take the weight of your payload and balance them on an area roughly the size of two footballs. The power of the truck’s factory spring suspension is completely taken out of use.

If you’ve already installed airbags on your truck and experience these side effects, we have a solution for you.

It is typical to run about 70-80 pounds of air pressure or more in the airbags to support a load like a truck camper. This amount of pressure is needed to level the vehicle, but causes an uncomfortable and rough ride. On your unloaded truck, go ahead and deflate your airbags. Many have found that 30 pounds of air pressure will cause a loaded truck to remain level, yet still incorporate the use of the vehicle’s factory springs.

Install quick-disconnect StableLoad suspension stabilizers on your lower overloads. By engaging the StableLoads, the space between the lower overload and main spring pack on your truck’s suspension is filled, putting the factory springs to use as they were intended.

At this point, load up the vehicle and take a drive with the StableLoads. You will find:
      -  StableLoads help eliminate sag and level your vehicle
      -  Side-to-side sway, body roll and porpoising is dramatically reduced
      -  Ride quality and handling is improved, creating a safer driving experience

If needed, eliminate any remaining sag by adding additional air back into the airbags. Many have found that they can reduce the air pressure from 70-80 pounds, to only about 30 pounds. This will allow the loaded truck to remain level, yet still incorporate the use of the vehicle’s factory springs.

If you are still deciding on the best suspension upgrade for your vehicle, we recommend starting with StableLoads. The combination of upper and lower StableLoads will resolve 100 percent of your suspension issues.

Many customers who installed the StableLoad suspension stabilizer found they did not have to move forward with installing airbags on their truck.


We also discussed the use of airbags with StableLoads at a recent rally where rally-goers took the StableLoad Challenge.

For the StableLoad Challenge, folks had the opportunity to test-drive the same Ford F-150 truck with and without the StableLoads. We placed 2,800 pounds of gravel in the bed to simulate a significant load similar to a truck camper.

Test driver Lisa Gord mentions the horrible bounce that airbags cause on her personal truck, causing her husband to lose his stomach every time they hit a bump!

What kind of aftermarket suspension upgrade should I get?

Towing a trailer, 5th wheel or toy hauler? Hauling a truck camper or other heavy payloads? You might be wondering, what are my options for suspension upgrades?

b2ap3_thumbnail_suspensiontowing.jpgWith a loaded vehicle, its suspension is under heavy stress. While maneuvering turns or hitting bumps in the road, the added weight can cause bouncing, bucking, severe side-to-side sway and body roll. This is not only an uncomfortable and potentially unsafe ride for the driver, but it can also cause strain and additional wear on the truck and its performance.

Options for aftermarket vehicle suspension upgrades include sway bars, add-on leaf springs, shocks, airbags and StableLoads. With several aftermarket suspension products on the market, making a decision becomes daunting. Let’s take a closer look at the benefits and potential negative side effects of each suspension modification.

The purpose of sway bars is to make a connection between the truck frame and its axles with a spring steel bar, reducing sway and body roll.

Add-on leaf springs help to increase the spring rate of your factory springs to eliminate sag and sway.

Although both of these alternatives may be effective in eliminating sway, the side effects result in a much harsher ride due to the stiffened suspension.

Additional aftermarket suspension upgrade options include shocks and airbags.

Shocks act as a dampener by resisting movement between the body and axle to help eliminate body roll.

Airbags inflate with air pressure to lift the truck frame away from the axle and help level the truck. A side effect of shocks and airbags lies within the potential for leaks. Not only do both significantly stiffen your ride, airbags will often increase side-to-side sway of the vehicle because it takes the weight off of the factory suspension.

The StableLoads combine all of the benefits of all these products but without any negative side effects.  


The purpose of the StableLoad is to treat the root problem by working with your factory leaf springs, rather then against them. The StableLoad suspension stabilizer puts the truck’s full factory suspension into use and equally disperses the weight of the load. By engaging your overload springs sooner, you’re vehicle can operate at its best potential.

After upgrading your suspension with the StableLoad, what happens when your vehicle is unloaded?

If you use your truck as a daily driver and aren’t in need of a permanent modification, the lower StableLoad application is the perfect solution. With the ability to engage and disengage in seconds, enjoy the convenience of returning to your comfortable factory ride when you’re not towing or hauling.

To engage or Torklift Jen

Sometimes you tow, sometimes you don’t.  That’s OK, I understand, a full time engagement can be quite a commitment!


So, what do you do when you want to have the best of both worlds?


polaroid22Most vehicle suspension systems aren’t designed to master the mechanics of everyday driving with ultimate comfort, safety, and performance and also be able to deliver the same ride with the added forces that occur while heavy towing and hauling.  You’ll find that a heavy load has you reaching for your sunglasses when driving in the dark. This is because the weight put on the rear and tongue forces your headlights right into the eyes of oncoming drivers, their brights flashing reminds you that you’ve got a problem.


Also, with your added weight, you will also experience swaying, bucking, reduced braking control with the associated longer stopping distances and a general feel of instability.  Airbags are a common go to aid for this issue, they are great for leveling, but they are not working with the physics of the problem.  They lift the weight off of the factory-engineered stock spring suspension.  This means you are taking the majority of the weight off the factory leaf spring suspension and are now carrying the weight on an area roughly the size of two footballs.   This is why the increased bounce and roll is felt.


A full time engagement to suspension add-on products like bump stops, airbags, and added leafs could mean a stiffer ride when unloaded, handling issues when loaded, or having to maintain air pressure and possible material breakdown and blowouts.polaroid23


Here enters in a suspension upgrade product that will work in conjunction with the stock factory suspension for the best ride while towing and hauling and disengage fully when not in use.


I recently participated in an install of the StableLoad product and I left out the easiest, but most unique part.  To engage the product when your are going to tow or haul simply use a 3/8” ratchet and extension to rotate the wedge pack between the overload and main spring pack.  You insert the included pin and clip to secure the wedge in the engaged or disengaged position.  This is literally done in seconds, with no commitment when you’re not towing and hauling.  I have now mastered the forces!
