Crower UL95133 Ultra Light Big Block Chevy Crankshaft 4.000 Stroke

Crower produces camshafts, crankshafts, connecting rods, and valve train components for a wide range of racing and performance applications, from the dragstrip to off-road. With a variety of options and materials, Crower is likely to have a solution to fit your particular need. These Crower Ultra Light forged steel crankshafts are precision-machined from premium 4340 NT forgings with ultra-light profiling, pendulum undercutting, center counterweight removal, four lightning holes, and radius edges. The smaller outside diameter quickens throttle response, reduces stress and wear, creates less drag in oil, and increases horsepower and torque. Crower Ultra Light forged steel crankshafts are built to order; please specify the required length and main journal size when ordering.
