Good To Know

Q: Do I need to replace the clutch basket at the same time? A: Not always, but inspect the basket fingers for notching and replace it if the plates catch. A worn basket will shorten the life of a new hub.

Q: Does this hub come with springs or bolts? A: This listing covers the inner hub itself. Reuse or replace the springs, bolts, and plates according to your service manual.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
