  1. Rated 5 out of 5

    I tried my hardest to break this set up and it took it like a champ. You can control your ski lift much better and you never drag those heavy torsion springs when side hilling. This kit is a huge improvement over the stock suspension

    You get to control/adjust ski lift much more than with stock set up, but whats even better is the t-motion lockout. The sled is much more predictable + it holds a sidehill way better when the snow gets a little harder. Best bang for the buck mod I ever did
