CRANK CHEV 454 FORGED 4.25str 2 pce rms INT BAL

Eagle's forged 4340 steel crankshafts are great for high-performance applications. They feature non-twist forging, go through a multi-stage heat-treatment process, and are stress-relieved and shot-peened. These cranks are X-rayed, magnafluxed, and sonic tested, so you know you're getting a top-quality piece. Each crankshaft has cross-drilled and chamfered oil holes for improved oiling, a .125 inch. radius on the 2.2 inch rod and 2.749 inch main journals for increased strength, and the journals are precision-ground and micro-polished to less than 5 RA. A target bobweight of +/- 2 percent greatly reduces balancing time. For use with a 2 piece rear main seal, and is internally balanced.
