Specs At A Glance

Good To Know

Q: How do I know this ring set fits my piston? A: Match the 66.75mm bore size and the 2628CD part number to your existing piston before ordering. Ring sets are sized to a specific piston, so an incorrect match can cause poor sealing.

Q: Can I install these rings without checking end gap? A: No, ring end gap should always be measured and set for your application during assembly. Proper gap helps sealing and prevents ring butting as the engine heats up.

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