Power Pak Forged Piston Kits
Race-proven forged pistons with phosphate dry-lube coating resist pin galling and ring micro- weld during start-up. Skirts are coated with anti-friction Grafal to prevent scuffing. Flat-top and domed pistons are available, and are machined for 1mm top and second compression rings, and 2mm oil rings (unless specified). Set of eight pistons includes wrist pins, locks, and perfor- mance piston rings.
