The 850 PRO Series has been completely designed to push the limits of strength, durability, and performance. 12-point nut and stud mounting system Next-generation driven hub design The FX 850 PRO replaces the traditional 6-post aluminum setup with a 12-post, heat-treated steel foundation. The new design delivers unmatched structural integrity, resisting flex, wear, and failure under extreme torque and heat. The re-engineered driven hub takes performance even further. By utilizing a single, precision-driven hub instead of multiple contact points, installation is faster and alignment is cleaner. More importantly, it maintains constant, even engagement with the transmission input shaft—reducing spline wear and increasing reliability when it matters most. Available in twin or triple disc rigid configurations, the FX 850 PRO Series is equipped with ceramic friction materials designed to handle serious abuse on the street or track. Clutch kits and Flywheels are SFI Certified, meeting performance standards for the automotive and motorsport industry.
