Specs At A Glance

Good To Know

Q: How do I confirm this ring set fits my engine? A: Check that your piston is a 65.00mm Wiseco piston that calls for the 2559CS ring set. Bore size and ring set number both need to match your existing piston.

Q: Should ring end gap be checked on a new set? A: Yes, measure end gap in the cylinder before assembly even with new rings. Proper gap helps the 65.00mm rings seal and avoids binding as they heat up.

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