With a brand new truck there are several expectations, one of which being able to handle 1/4 to at least 1/2 of the rated towing capacity easily. Well my 2020 Sierra with the max towing and 6.2L motor couldn't without several inches of squat. With the main purpose of towing our travel trailer, something had to be done, cue the hours upon hours of researching the best solution to the problem. Air bags, lift kits, spring swaps, a differrnt weight distribution hitch (currently using Center Line TS rated for 1200lbs tongue weight). I called up the RAS guys, Sean was there to answer all my questions...... Came very quickly, packaged properly no damage. But here's the proof it works, 2 measurements, before with trailer and after where it eliminated my squatting issues, along with a photo of the truck with a 4800lb travel trailer attached sitting level. If you need a solution to weak leafs and improve road handling while towing and NOT make the ride harsh, this is THE ONLY kit for you!!
