STM Powersports RZR Pro R Primary Billet Clutch
STM Powersports RZR Pro R Primary Billet Clutch

All new design for the New 4 Cylinder Engines 

The design is similar to our HD clutches from other machines that offer a spread cam arm pin diameter. This allows for more leverage through the cam arms. 

This clutch also incorporates a lager diameter 2 way bearing design for longer lifespan through use and smoother take off. 

 Must select a weight and spring kit. 

Combined with our Pandemyk Performance Stage 2 Tune we have seen top end speeds 118+ MPH with both STM primary and secondary together.
