Frequently Asked Questions

What's included in this kit?

Friction plates only. You will need to source or reuse steel plates and clutch springs separately.

Will this fit my 5-speed Big Twin?

No — this kit is designed for 4-speed Big Twin transmissions only. 5-speed models require a different part number.

Do I need to replace the steel plates too?

Friction plates wear faster than steel plates. You can reuse existing steel plates if they are not damaged or warped.

How do the groove patterns help?

The grooves direct oil flow across the friction surfaces to keep the clutch cooler and extend plate life under load.
