The MAHLE PowerPak is a complete, race proven piston assembly kit composed 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 lubricant that is used to protect against ring micro-welding and pin galling during initial startup and break in.
