HOT ROD SLED SHOP REV GEN4 850 ETEC 2017-18 Ski-doo Renegade clutch kit. This kit accelerates incredibly hard, has great backshift. The engagement is lower than stock and and grabs the belt harder for less slip and heat. Our clutch kit increased top speed over stock clutching by 3 mph in testing on a 2018 850 Renegade through break-in. Our kit will put several sled lengths on a stock sled or your buddies stage 8 clutch kit while back shifting faster to increase the fun factor from corner to corner trail blasting as well! The kit includes our HRSS-PDM billet steel, hardened, electroless nickel plated adjustable clutch weights, progressive helix, primary spring, and secondary spring. We include calibrations for various aftermarket pipes and modifications including Jaws Pipes, Bikeman Pipes, Dynoport Pipes, D& D pipes and various porting packages.
