How does truck sag affect my vehicle?

sag-towing-trailer-camperRear end truck sag from towing or hauling

Has the term ‘sagging’ ever been associated with something positive? If your truck or vehicle displays rear end sag when towing a trailer or hauling a heavy load, it’s important to address the rear end sag by finding a proper solution that levels the vehicle. Truck sag, also referred to as truck squat, is the visible effect of payload on the rear end axle, causing the nose of the vehicle to shoot upwards while the back end tilts downward. Some folks underestimate the severity of driving a vehicle in this position. The handling dynamic of your vehicle will suffer greatly.

With rear end sag, you’ll experience these side effects:tire-footprintUneven tire footprint

  1. Increased braking distance, inability to stop
  2. Steering is completely thrown off  -- steering is loose or has a feeling of ‘floating’ because the vehicle’s maneuvering capabilities are unresponsive
  3. Misaligned steering leads to increased tire wear and uneven tire footprint, which can potentially decrease your fuel mileage

wheel-drivingInability to gain controlWhen you’re driving with vehicle sag, you’ll likely stress to focus your mind and keep the vehicle in its lane on the road, often overcompensating with corrective steering because it’s significantly altered. It’s unsafe and difficult to gain control of a vehicle when operating under these conditions.

 

We introduced the StableLoad Challenge at a camping rally to those who tow or haul often. By placing 2,800-pound load in the back of two identical Ford F150 trucks, we had test-drivers experience the suspension of both vehicles, one with the StableLoad suspension stabilizer turned on, the other without.

 We parked the trucks side by side as we gathered test-drivers at the rally. Before anyone even drove the vehicles, rally-goers could physically see the difference between the trucks by the amount of sag. The Ford truck without the StableLoads suspension stabilizer had rear end sag while the Ford truck with StableLoads installed sat level.

 How does the lower quick-disconnect StableLoad application correct rear end sag? The StableLoads effectively reduce the amount of rear end sag by pre-activating the vehicle’s factory overload leaf springs. Not only for trucks, the StableLoads universally fit on any truck, van, SUV and light commercial vehicles that come equipped with overload leaf springs.

By occupying the gap between the leaf spring pack and lower overload, the stabilizing effect of the leaf springs are activated much sooner. With the factory suspension put to use as it’s designed, you experience a leveled vehicle and reduction in stressful handling characteristics such as side-to-side sway, body roll and porpoising.

The condition of leaf springs is different on each vehicle, meaning the space or clearance between the upper leaf spring pack and lower overload leaf spring varies. Each StableLoad comes with three specially designed wedges that are adjustable to accommodate this.

Each individual wedge plate is 1/4 inch thick and has special tapered edges built in. The more spacers or wedges that fit into the gap increase the level of effectiveness. However, if only one or two of the wedges are used, the stabilizing effects of the quick disconnect StableLoad are still noticeable.

The wedge pack easily rotates into position when towing or hauling, much like an on and off switch for your suspension. With the ability to engage and disengage, the StableLoads allow the convenience of returning to your comfortable factory ride when you’re not towing or hauling.

Those who took the StableLoad Challenge were amazed at how StableLoads helped eliminate truck squat. When rally-goer Paul Bechtel test-drove the Ford F-150 truck with StableLoads turned on, he felt the difference in handling immediately.

“Wow, what a difference,” said Bechtel. “I have a lot more control. The ride is very smooth and porpoising is reduced.”

Floating down the freeway? How to gain control and eliminate truck sway

floating-on-freewaySinking vehicles on a flooded freeway

It’s no surprise that when it comes to floating down the freeway, the picture above might be the first that comes to mind. We know that vehicles do not naturally float but flooding aside, have you ever felt loss of vehicle control at high speeds when towing a trailer or hauling a heavy load?

The severe truck swaying and wobbling at high speeds feels like you’re floating down the freeway. Certainly not on cloud nine, as the inability to gain control will cause you some serious white knuckles from the tight grip on your steering wheel. Attempting to switch lanes throws the vehicle into a dangerous rocking motion.

 

To remedy poor handling and solve drivability issues on your truck, Torklift International StableLoad suspension stabilizer should be your first approach. As a simple and most effective way to upgrade your truck’s suspension, the StableLoads address and correct concerning handling characteristics such as:
     -  Side-to-side truck swayb2ap3_thumbnail_stableload-display.pngStableLoads engaged and disengaged
     -  Rocking motion, porpoising
     -  Body roll
     -  Vehicle sag

By putting the vehicle’s factory suspension into effect sooner and equally dispersing any payload you are towing or hauling, your vehicle operates at its best potential.

Torklift International StableLoad suspension stabilizer is the only suspension modification can quickly be disconnected. This feature is convenient for those who use their truck as a daily driver and don’t want a permanent suspension modification.

rickTo put the StableLoads to the true test, we introduced the StableLoad Challenge. By giving those experienced with towing and hauling the opportunity to test-drive a Ford truck both with and without the suspension upgrade, we were curious to see if they detected a difference in ride quality.

With two identical Ford F-150s, 2,800 pounds was loaded in each truck bed to simulate payload of a truck camper or trailer. Test drivers were eager to experience how StableLoads affect the Ford truck suspension.

Rick Leff wanted the opportunity to give StableLoads a thorough review. As he climbed behind the wheel of the Ford F150 with StableLoads engaged, he mentioned he could feel the difference immediately.

“You can tell the difference already,” said Leff. “Where I can tell the difference a lot is the back and forth movement.”

Leff mentions the floating feeling while driving a trailer at high speeds.

As the speed of the vehicle increases, the stabilizing effects are even more noticeable. The poor handling and feeling of “floating” is greatly reduced when the StableLoads are engaged.

 Overall, Leff was pleased with the difference in ride quality that the StableLoad suspension stabilizer provided.

“This was a good ride, I can really tell the difference,” said Leff.
