*WARNING* Your vehicle may have a lower tow rating than this trailer hitch. If your vehicle’s tow rating is less than the rated towing capacity on your Torklift Central trailer hitch, your trailer hitch capacity is limited to your vehicle’s factory rated towing capacity.
***IMPORTANT NOTICE:
While EcoHitch®️ trailer hitches are built with high-strength materials and tested for exceptional weight ratings, your vehicle’s factory towing capacities are the ultimate limit. Always refer to your vehicle’s owner’s manual to determine its maximum towing and tongue weight ratings. No aftermarket hitch or accessory can increase your vehicle’s factory-rated towing capacities.
Using hauling accessories like extensions, cargo trays, bike racks, or other accessories that extend the load out from the trailer hitch, will significantly reduce the tongue weight capacity of your hitch system.
To estimate how your setup will affect tongue weight, we recommend using our Maximum Hitch Weight (Tongue Weight) Estimator before hauling your payload (cargo trays, bike racks, etc).
Disclaimer: It is the user’s responsibility to ensure safe towing practices and to confirm that all loads fall within the limits of the lowest-rated component in the towing system. Torklift is not liable for any damage or injury resulting from the misuse or overloading of towing/hauling equipment.

Customer Reviews
I'm just worried what are the tips and suggestions on 6 speed wrx in order to prevent any transmission damages/ burning. I don't speed with the trailer so just between 2-3k rpm between gears.
After reading forum posts and other reviews I decided to pull the other hitch off and install the ecohitch. Since I'd already installed one hitch and had practice, installing the ecohitch was a breeze. There are no rattles, it looks great since you can't see it, and it fits perfectly. I got a little creative with the bumper knockout and made it easily removable so when I'm not hauling a bike my Subaru looks completely normal in the back.
The ecohitch is worth the premium over the competition. It works better, looks better, is better.
