Frequently Asked Questions

Will this fit my Sportster?

No — this diaphragm spring is for Big Twin clutches only. Sportster models use a different pressure plate assembly.

Is this a direct replacement for the factory spring?

Yes. It's manufactured to OEM specifications and drops into your existing clutch basket without modification.

How often should I replace the diaphragm spring?

Replace it if you experience clutch slippage, hard engagement, or lever feel changes. Many riders replace it during a full clutch rebuild.

Do I need to replace the entire clutch basket?

No — the diaphragm spring is a standalone component that fits into your current basket.
