Eagle 273 318 340 360 5.2 and 5.9 Magnum crankshafts are 100% x-ray, magnafluxed and sonic tested, stress relieved and shot peened. Eagle forged cranks also have a .125" radius on rod and main journals for improved strength. Chamfered bearings must be used to clear the journal radius. Cast steel model cranks can use stock type bearings with a standard chamfer. These crankshafts are drilled to accept a pilot bearing, so they can be used in automatic transmission and manual transmission applications.
We have a large selection of Molnar Technologies premium 4340 forged steel stroker cranks available also. You can view the full list on our website here: Molnar SBM Cranks
