Description
Forged Super Duty series for the Milwaukee Eight engine. With hard anodized crown and top ring groove to reflect heat and prevent ring to groove 'micro-welding'. The Line2Line abradable self-lubricating powder coating technique allows zero tolerance installation, final tolerance will be 0.003". The piston creates its own perfect tolerance during run-in, the coating automatically gives the tightest possible & perfect piston to cylinder fit for no piston rock and best possible ring seal.
