CROWER has lightened up their new version of the popular Crower “Standard” design to reduce the weight approximately 2 lbs over the previous design. Their proprietary premium grade USA Made 4340 "Non-Twist" Forging is the foundation for this crankshaft. This is the same premium forging that is use to make the Maxi-Light and Ultra-Light crankshafts. The Crower “Standard” crankshaft 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. This design 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 53-57 lbs dependent upon your specifications. Gun drilled Mains, Knife Edge and Balancing available for an extra fee.
