This kit has enough adjustability to compensate for all the power levels for all EVP RZR Pro R tune files. This means you can run stock injector tunes or our big injector tunes. This kit keeps clutch engagement rpm close to stock for a smooth take off, but has the adjustability to add a higher engagement spring. In addition, the "non-notched" weights are fully adjustable so you can clutch for virtually any stock turbo power level.
