The Hot Rod Sled Shop Clutch Kit for the Summit T3 sleds is complete. We have testing from Sea-level to 10K elevation completed and this kit performs! The kit includes HRSS2 ramps, HRSS helix, HRSS adjustable pin kit, HRSS primary spring, secondary spring and a QRS Slickshift Bearing. We achieved better track speed , cooler sheaves, lighter engagement, and very consistant rpm on long heat soaked pulls. The backshift is quick and our ramp holds back better than stock on descents. If you have a bigbore T3 we have you covered there also.
