These Manley Pro Series crankshafts can make your short block bulletproof. They feature forged 4340 construction and undergo a multi-step heat-treatment process and are then nitride coated for added strength. The crankshafts are stress-relieved, shot-peened, and magnafluxed. The Manley Pro Series crankshafts have micro-polished large .125 in. radius journals, gun-drilled mains, and lightened rod journals for weight reduction. The counterweights are fully profiled, and they are designed for internal balancing.
