Brock’s Performance Dual Stage Cushion Rings are engineered to withstand the extreme heat and stress that comes with high-performance riding. Over time, or following a clutch failure, rings can develop flat spots, distortion, or heat damage that reintroduces chatter and grab—the very issues the Cushion Kit was designed to eliminate. Replacing the ring ensures your Clutch Cushion Kit continues to deliver optimum performance and reliability.
