Dynojet Heavy Clutch Arm Upgrade Kit 2017-2021 Polaris RZR XPT

Each clutch arm weight is 4.48g heavier than those in the regular Polaris RZR XP Turbo clutch kit. By adding heavier weights, the RPM is kept in check while providing optimal primary clamping force against the belt on high horsepower applications. This is essential for drivers using E85 fuel or cranking out massive amounts of horsepower who need more adjustment. This kit is a must-have if you use E85 fuel or if you’ve installed a steeper helix. It helps keep the RPM under control without bouncing off the rev limiter too quickly and is intended to be used in conjunction with Dynojet clutch springs. Includes 3 Clutch Arms and 48 Magnets (3/8”).
