Specs At A Glance

Good To Know

Q: How do I confirm this ring set matches my piston? A: Check the 73.50mm bore and the 2894CD part number against your piston documentation before buying. Ring sets are bore and piston specific, so both must match.

Q: Do I need to gap the rings before install? A: Always measure and file ring end gaps to the piston maker's spec during assembly. Skipping this step risks poor sealing on 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.
