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 (not to be confused with a thermal film coating) 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.
