Specs At A Glance

Good To Know

Q: How do I confirm this ring set fits my piston? A: Match the 66.00mm ring diameter and the Wiseco part number 2598CD against your piston and cylinder specs before ordering. Checking the bore and piston application first avoids a mismatched set.

Q: Are all rings in the set the same? A: Piston ring sets typically include compression and oil rings sized for one piston, so install each ring 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.
