Zestaw tłoków KB, M8 114″/117″ do 124″ z dużym otworem. +.005″

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.
