4214510 is a 4-pad spring-centered race disc made with high quality ceramic friction materials that provides a moderate wear rates and high heat tolerance. The engagement is harsher, but shifting is faster. The heavy duty torsional dampening springs are stronger, in most cases, than standard springs and are provided in the best sizes and spring rates to suit the application. It utilizes wraparound spring windows, thicker retainer stampings and a heat-treated, spring steel drive plate to provide support, reduce stress concentrations and increase strength and reliability. The race disc features a heat-treated spring steel drive plate and is well-suited for the smaller disc sizes in smaller engines. High burst strength and holds 28% more torque than typical organic materials.
