Apraksts
Forged Super Duty series for the Milwaukee Eight 114" and 117" engine for a 128" big bore conversion. Designed to work with both oil/water cooled engines and up to 3mm larger valves. 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.
Note: Fits 114/117" M8 engines with stock 4.5" stroke. Aftermarket 4.25" bore cylinders are required. For up to 3mm larger valves.
