Good To Know

Q: Can I use these for a high-performance build? A: These are designed for standard bore replacements, so they are best for restoring stock performance rather than extreme modifications.

Q: Why is the ring gap important? A: Correct ring gap prevents the rings from binding or expanding too much as the engine heats up to its operating temperature.

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