Good To Know

Q: What does an inner clutch hub do? A: It holds the clutch plates and transmits 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.
