Good To Know

Q: Are the rings pre-gapped? A: Piston rings come pre-gapped, but final gap should always be checked and adjusted to cylinder specs during installation.

Q: Do I need to replace the wrist pins? A: Wrist pins are included in the kit, but we recommend reusing original clips unless new ones are provided.

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