The KB Pistons Super Duty Piston, part number KB542LCA.010, is designed for 4.125-inch bore M8 114/117 to 120-inch engines with a +.010 size option. This direct replacement motor vehicle part brings advanced engineering to your build, incorporating an anodized top ring groove and crown, forced wrist pin oiling, and reliable round wire locks.
Engineered for performance, the piston utilizes a Line2Line abradable skirt coating applied to .003-inch total thickness, ensuring a zero initial fit that hones in for tight, quiet running clearance. It comes paired with a premium Hastings 1.2mm 1.2mm 3.0mm steel nitride top ring and a ductile Napier second ring. Verified fitment covers select Harley Davidson motorcycles from 2017 through 2020, such as the Road King, Tri Glide Ultra Classic, Electra Glide Ultra Limited, CVO Limited, and Street Glide. Please verify fitment and specifications before ordering.
