Specs At A Glance

Good To Know

Q: How do I confirm this ring set fits my piston? A: Match the 65.50mm ring diameter and the Wiseco part number 2579XC to your piston and cylinder specs before ordering. Verifying the bore and piston application first prevents a mismatched set.

Q: Are all rings in the set the same? A: Piston ring sets normally include compression and oil rings sized for one piston, so each ring goes in its correct groove. Follow the piston maker's ring orientation and end gap guidance during assembly.

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