Get the performance you need with the Chevrolet Performance 383 Crankshaft. Crankshafts convert the up and down motion of the piston to a rotation that transfers through the gearbox to move the wheels. The forged crankshaft is made of 4340 alloy steel. It is used to create 383-cubic-inch engines with a 3.800-inch stroke, and requires connecting rods, a bearing kit, standard pistons or 0.030-inch oversize pistons, an externally balanced balancer, and a 1986-and-later one-piece rear crank seal design flywheel or flexplate.
