Specs At A Glance

Good To Know

Q: Does this kit include a cylinder? A: No, this is a top end repair kit that includes the piston assembly only; the cylinder must be in good condition or replated separately.

Q: Is the piston pre-gapped? A: The rings are not pre-gapped; you should file-fit the rings to your cylinder bore for proper clearance.

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