The MAHLE Motorsports Power Pak kit is a high volume shelf stock program developed for high performance enthusiasts and sportsman class racers. The Power Pak PLUS pistons are predominately made from 2618 aluminum alloy to allow for higher strength, and improved temperature stability.
Power Pak feature includes:
- Forged piston for performance applications
- Fully-machined crown
- Grafal anti-Friction coating on skirts*
- Phosphate-coated to reduce micro-welding and pin galling**
- Pin bores binished on CNC boring equipment
- Deburred
- High strength, light weight steel pins
- Race proven round wire locks
- Low drag ring pak
- Light weight slipper kirt forgings
* MAHLE’s GRAFAL® skirt coating reduces drag, scuffing, friction and cylinder bore wear; reduces piston noise.
** 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 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.
