    1.5mm, 1.5mm, 3.0mm file fit performance ring set is included. For 383 c.i. S/B Chevy (4.000" bore x 3.75" stroke). Choose oversize diameter needed.

    1. Mahle's phosphate coating provides the grey appearance to the 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.
    2. Mahle’s GRAFAL skirt coating reduces drag, scuffing, friction and cylinder bore wear; reduces piston noise.
