KB, M8 107″ to 124″ big bore conversion piston kit. STD

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. Note: Fits 107″ M8 engines. Works with stock 4.375″ stroke and stock unmodified heads. Aftermarket 4.25″ bore cylinders are required. – 11.4:1 CR – Piston weight: OEM – Engine displacement: 124″ – Bore: 4.25″ – Stroke: 4.375″ (stock 107″ engine) – Ring pack: 1.5mm; 1.5mm; 3.0mm – Top land: .230 – Pin number: .9270×2.250x.180-SCR415H – Pin type: Floating – Pin diameter: .927″ – Compression height: 1.155″ – Crown Type: Dome – Crown (cc): -2cc – Alloy: Forged 4032 Alloy
