Specs At A Glance

Good To Know

Q: How often should a carbon ring be replaced? A: It is typically replaced during driveline service or whenever the bellows and support ring are refreshed, since the sealing face wears with use. Inspect it any time the driveshaft is removed.

Q: Can this ring be reused if it looks fine? A: A carbon ring that shows scoring, cracks, or a worn sealing face should be replaced rather than reused. Reinstalling a worn ring risks water intrusion at the hull seal.

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