Track Smart 4340 Forged Steel Crankshafts
Computer designed, “Track Smart” 4340 forged crankshafts are constructed using precisely placed counterweights for improved balance and reduced bearing loads. All rod journals are drilled and counterweights profiled for piston clearance. All journals include large, .125" radii and require chamfered bearings. Crankshafts are additionally hardened with a deep nitride for increased wear resistance.
