Brock’s Performance Clutch Cushion Kit replacement Dual Stage Cushion Rings can be damaged (flat spots, distorted outer casing, etc…) due to clutch failure/excessive heat, etc… which can lead to the same grab/chatter that the Clutch Cushion Kit is designed to eliminate.

Special Note: If you replace this ring for any reason other than after a very long life for general maintenance purposes OR after a catastrophic clutch failure, which created a tremendous amount of heat, you have something else wrong.
Examples: You have strayed from our cushion spring configuration, wrong oil type, incorrect gearing, wrong launch RPM/technique or a multitude of other potential issues.
