Light-Weight Small Block Chevrolet 4.125 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 44-50 lbs dependent upon your specifications. This design can be customized for you to meet 48lb or 50lb class restriction requirements. Gun drilled Mains, Knife Edge and Balancing available for an extra fee.
