Graphite piston skirt coating (2 pistons). More durable than Molly or other coatings. Recommended for all pistons for tighter clearance.


This coating will give you a tight installation clearance of approx .003” The coating will polish at the interference area on break in and leave you with a piston that is tighter in the bore than you would have with an uncoated piston. Life of the piston is approx doubled compared to a bare aluminum piston. Reduced friction, increases HP and extends cylinder life.
