Specs At A Glance

Good To Know

Q: How do I know this ring set fits my piston? A: Match the 73.50mm bore and the 2894LK part number to your piston spec sheet before ordering. Ring sets are bore and piston specific, so the number must line up.

Q: Are ring end gaps set out of the box? A: Ring gaps should always be checked and filed to your piston manufacturer's spec during assembly. Never assume a drop-in fit for a performance build.

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