Good To Know

Q: Does this cylinder come with a piston or rings? A: No, this listing covers the Nikasil plated cylinder only, so pistons, rings, and gaskets must be sourced separately. Confirm bore size and piston clearance before assembly.

Q: Is the plating already applied? A: Yes, the bore is Nikasil plated as supplied, so no additional plating step is required. Check the bore for damage on arrival before installation.

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