*The crankshaft bobweight listed in the tables above refers to the "target" bobweight for each crank listed. You must have these Eagle cranks balanced to work with the rest of your rotating assembly before installation in your engine.
The cast steel cranks are intended to be used in external balance configurations, and the forged steel cranks are intended to be used in internal balance installations.
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.
