So I finally had time to install this kit. Before I installed it, the chain loop on factory hitch (rims and tires) was 21" to the ground. After installation AND no air in the bags, it was the same, 21".
I inflated to 6 psi which raise it about an inch to 22". I hooked up my boat trailer with about 200 pound tongue weight and the truck dropped about a 0.5". Unhooked boat trailer and went for a ride with 6psi in air bags. I stepped on the gas hard (as always), launched the truck and to my surprise, the torque steer was not noticeable to me. Makes sense. Repeated a few times, because why not!
So now I should be able to do light/medium duty towing without a saggy ass. I have a 2500 Diesel for my HD towing but the TRX is such a fun truck to drive, why not tow with it too.
So if you think you will be towing with your TRX, I recommend this kit from Steve at Timber Grove. Has all parts needed to install.
