Good To Know

Q: What does an inner clutch hub do? A: It holds the clutch plates and transfers drive from the clutch pack to the transmission input shaft. A worn hub can cause notching, drag, or inconsistent clutch engagement.

Q: Should the inner hub be replaced with the clutch plates? A: It is common practice to inspect the hub whenever the clutch is opened and replace it if the splines are notched or worn. Confirm your model year before ordering.

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