Description: A good foundation for your rotating assembly. These forged 4130 steel crankshafts from Eagle Specialty Products are a terrific foundation for your engine build. These cranks go through a multi-stage heat-treatment process, and have medium frequency induction-hardened rod and main journal surfaces for superior wear resistance. The journals are precision-ground and micro-polished. All 4130 cranks are 100 percent X-rayed, magnafluxed, and sonic tested, so you can be assured you are getting a quality product. They are also stress-relieved, shot-peened, and indexed for correct stroke. No machining is required for block clearance, and the oil holes are cross-drilled and chamfered for improved oiling. These cranks feature a .125 in. radius on the rod, main journals, rear seal, and snout for increased strength, and the counterweights are designed for easy balancing. Plus, their target bobweight of +/-2 percent reduces balancing time! (minimize)
