The MAHLE Motorsports Power Pak was designed as a completely finished drop-in piston assembly. Other than filing the included performance ring set, everything else is done for you. Design technology derived from 80+ years of piston manufacturing for everything from OEM to Formula1 is used to produce the best piston at the best possible value. PowerPak kits are available for most popular applications from sport compacts to 600+ cubic inch big blocks.*** ***These pistons are designed primarily for off highway use. Check federal law and emission regulations.
POWERPAK
The MAHLE Motorsports Power Pak is a complete, race proven piston assembly kit comprised of hand deburred, all forged, performance coated pistons, high quality steel pins, round wire locks and low drag performance rings. Performance coatings include a phosphate dry lubricate that is used to protect against ring micro-welding and pin galling during initial startup and break in. For added performance, MAHLE applies its proprietary Grafal® anti-friction coating to each piston skirt.
FEATURES • 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 skirt 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.
