EVP Tapp Roller Primary Clutch Kit for Polaris RZR Pro R

All EVP TAPP Primary Clutch Calibrations available on this page are designed specifically for RZR Pro R's WITH AN EVP ECU POWER FLASH OR PARAGON TURBO SYSTEM.

Don't think a TAPP clutch can be any smoother and more responsive than it already is? Think again. The all-new Roller Spider design for TAPP Primary Clutches replaces the original button spider assembly for an instant power delivery due to the reduction in friction between the spider and movable sheave. This results in even better belt grip than before, lower belt temps, better belt life, and buttery smooth engagemwent that's guaranteed to keep your car dialed in any riding condition. The patent-pending TAPP Roller Primary Clutch is the next revolution in clutching technology.

All EVP Spec TAPP primary clutch kits include full standard weight kit as well as tungsten TAPP Clutch Race Weights (set of 8).


Running a non-EVP tune and still want to enjoy all the benefits and performance of an EVP.MOde Spec TAPP primary clutch? No problem! TAPP clutches are renowned for being incredibly easy to tune and adjust. RPM engagement can be increased simply by flipping the ramps from side A to side B. Flipping two ramps to side B will increase engagement by 600-800 RPM, flipping all four ramps to side B can increase engagement even higher. Additionally, the adjustable clicker bolts can raise or lower engagement by 50-RPM increments for further fine-tuning.
