Specs At A Glance

Good To Know

Q: How do I know if my sled needs new rings? A: Low compression readings, hard starting, or visible cylinder scoring during a tear down all point to worn rings. Check compression on all cylinders before ordering.

Q: Should I hone the cylinder before installing these rings? A: A light hone helps new rings seat against the cylinder wall. Inspect the bore for damage first, since worn plating or deep scoring needs more than rings.

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