Specs At A Glance

Good To Know

Q: Do I need to check clearances after installing this thrust ring? A: Yes, always verify crankshaft end play with a dial indicator after assembly to confirm the ring provides the specified clearance.

Q: Can this thrust ring be reused if it looks fine? A: Thrust rings wear in ways that are hard to see by eye, so replacing them during any bottom end rebuild is safest.

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