Specs At A Glance

Q: Should the rings be lubricated during install? A: Apply a light coat of clean engine oil to the rings during piston installation. Q: How do I know if I need standard or oversized rings? A: Measure your cylinder diameter; if it matches factory specs, you need standard rings.

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