Light-Weight Big Block Chevrolet 4.500 Stroke Crankshaft

Light-Weight Big Block Chevrolet 4.500 Stroke Crankshaft

The smaller outside diameter of the Crower “Light-Weight” crankshaft design reduces rotating mass for quicker response and less drag. Our proprietary premium grade USA Made 4340 "Non-Twist" Forging is the foundation for this crankshaft. The Crower Light-Weight crankshaft has non-critical mass machined away through our lightweight profiling and center counterweight removal for a lighter rotating assembly. It is fully hand de-burred and all surfaces are smooth to the touch. This crankshaft features include 1/8 radii, premium heat treat processes, counter weight correct design and straight shot oiling. The Light-Weight comes standard with lightening holes in all rod journals. All rod & main sizes are standard unless otherwise specified. Specify rod length for proper counterweight clearance. Finish weight of this crankshaft will be 65-74 lbs dependent upon your specifications. Gun drilled Mains, Knife Edge and Balancing available for an extra fee.
