Mahle's PowerPak piston assemblies include forged pistons, piston rings, pins, and wire locks--all in one race-proven package. The pistons are hand-deburred and then coated with dry phosphate to protect against ring micro-welding and pin galling during initial startup. For additional performance, Mahle added its proprietary Grafal anti-friction coating to the piston skirts. Low drag rings, steel pins, and round wire locks complete the Mahle PowerPak package.
