Product Description
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.

IMPORTANT NOTE
If your Dual Stage Cushion Ring requires replacement for reasons other than normal long-term use or a catastrophic clutch failure with excessive heat, another underlying issue may be present. Possible causes include:
- Incorrect cushion spring configuration
- Improper oil type
- Wrong gearing or launch RPM
- Inconsistent launch technique
The intermittent temperature rating of these rings exceeds 550°F, far beyond the ~290°F limit of high-grade synthetic oils. If you’ve damaged a ring, it signals a serious problem that needs attention. For troubleshooting assistance, please contact our technical support team.
