KB, piston kit for M8 107" to 124" bore enlargement. STD

Forged Super Duty series for the Milwaukee Eight engine. With hard-anodised ring crown and top groove to reflect heat and prevent "micro-welding" between the ring and the groove. The Line2Line self-lubricating powder coating technique allows zero-clearance installation; the final clearance will be 0.003". The piston creates its own perfect clearance during break-in; the coating automatically provides the tightest, perfect fit between piston and cylinder, with no piston rock and the best possible ring sealing.
Note: Compatible with 107" M8 engines. Works with the original 4.375" stroke connecting rod and unmodified original cylinder heads. 4.25" bore aftermarket cylinders are required.
