  • The Mahle PowerPak is a complete, race proven piston assembly kit composed of hand deburred, forged, performance coated pistons, high quality steel pins, round wire locks and low drag performance rings.

    Performance coatings include a phosphate dry lubricant that is used to protect against ring micro-welding and pin galling during initial startup and break-in. For additional performance, Mahle applies its proprietary Grafal anti-friction coating to each piston skirt.

    Features
  • Forged Aluminum Pistons
  • CNC machined crown
  • Hand deburred finishing
  • Forced pin oiling with machined drain backs
  • Lightweight slipper skirt forgings
  • CNC finished pin bores
  • Forced Pin Oiling
  • Race Proven, reliable round wire locks, standard with every kit
  • Pre-fitted German steel pins noted for their high strength, light weight and durability
  • Phosphate coating - provides the grey appearance to the Mahle 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 oil system of the engine reached operating pressure; particularly useful during the initial start-up or break-in of engines to protect against galling and micro welding. Piston crown remains machine able.
  • Mahle's Grafal Skirt Coating - Reduces drag, scuffing, friction and cylinder bore wear; reduces piston noise.
  • Precision ring grooves for included piston rings
