GRAFAL skirt coating reduces drag, scuffing, friction and cylinder bore wear; reduces piston noise.

Phosphate coating provides the grey appearance to the PRO SERIES PISTON. This dry lubricant coating (not to be confused with a thermal film coating) provides a lubricant film in the pin bores and ring grooves until the oiling system of the engine reaches operating pressure; particularly useful during the initial start-up or break-in of engines to protect against galling and microwelding. The piston crown is still machineable.

 

NOTE: Price is for pistons only, rods not included.
