Recommended Suspension Enhancement to Reduce Axle Wrap when Towing with 2012 Toyota Tundra


I have a 2012 Toyota Tundra DC with the 5.7 motor and tow package. I have installed a gooseneck hitch and airbags. Truck is rated for 10,500 lbs, towing a fifth wheel that weighs about 10,000 lbs. I tow pretty infrequently, and dont want to ruin my soft ride while unloaded. Air bags only require about 30 psi to level the truck with about 1,500 lb pin weight. I am getting pretty violent front-to-rear bucking that starts when I hit a bump while accelerating. Using a go-pro, I determined the cause is spring wrap. Are there any traction bars or ladder bars available to alleviate my spring wrap problem?


Helpful Expert Reply:

The only option to assist in your towing experience due to axle wrap or wheel hop is to add the RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS4611TD. This system will attach to the leaf springs on your vehicle and stabilize the springs when under load. The RAS tension springs disengage when not under load so they will not change your unloaded ride.

If you also have side to side sway, then I recommend the Roadmaster Rear Anti-Sway Bar for Trucks # RM-1189-102 which is a confirmed fit for your 2012 Toyota Tundra and will improve the drivability and stability of your truck by helping balance weight transfer and reducing body roll. This will mount to your frame and your rear axle.
