2520CS Ring Set 64.00mm for Wiseco Piston Rings

Ring Set for Wiseco

This 64.00mm ring set is a replacement piston ring assembly designed to seal the combustion chamber and control oil on Wiseco-equipped engines, cross-referencing part number 2520CS.

Overview

This 64.00mm ring set provides the sealing elements needed to restore compression on a piston build. The ring set is sized at 64.00mm for a precise fit in the matching bore and is intended for riders and builders refreshing a top end. Each ring set is produced to the 2520CS specification so the dimensions and thickness match the piston it was made for.

Good To Know

Q: How do I know this ring set fits my piston? A: Match the 2520CS part number and the 64.00mm bore size to your existing piston and cylinder before ordering. Ring sets are matched to a specific piston, so the part number is the key check.

Q: Can I install these rings without replacing the piston? A: Yes, ring sets are commonly installed when the piston is still within spec and only the rings need replacing. Check ring end gap and cylinder condition 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.
