Info

The Mahle PowerPak pistons are a race proven lightweight forged design that are complete with rings, wrist pins and locks.  They are also completely phosphate coated plus feature an anti-friction Grafal skirt coating.  PowerPak pistons are made from 4032 aluminum alloy to allow for tighter cylinder to wall clearances, and improved temperature stability.

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.
