BMW S65 Stroker Crankshaft
Our S65 crankshaft comes standard at 83mm of stroke. Other strokes can be custom ordered and we can assist with engineering rods and pistons to complete your custom kit. As with our other billet crankshafts these 8 cylinder cranks are plasma nitrided, and dynamically balanced using bob weights of the actual rod/piston combination that will be used. This crankshaft is the basis for our S65 stroker kit that includes custom pistons, rods, and sleeves for your S65 block.
