Specs At A Glance

Good To Know

Q: How do I confirm this ring set fits my piston? A: Match the 55.00mm bore size and the Wiseco 2165XE part number against your piston or rebuild spec before ordering. Ring thickness and groove dimensions must also match the piston being used.

Q: Can I install new rings on a worn cylinder? A: New rings seal best in a cylinder that has been measured, honed, or replated to the correct bore size and taper. Installing them in a worn bore can lead to poor compression and oil consumption.

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