Eagle crankshafts are available for both the low deck, B Mopar engine and the high deck, RB Mopar engines. These forged stock stroke, and stroker cranks are for use in the Dodge, Plymouth, Chrysler, Mopar big block engines including the 361, 383, 400, 413, 426W and 440, as well as stroker engines built off of these base engines. All Eagle cranks for the big block Mopar engines are made of 4340 grade steel and are a non-twist forging.
Eagle crankshafts are 100% x-ray, magnafluxed and sonic tested, stress relieved and shot peened. Eagle cranks also have a .125" radius on rod and main journals for improved strength. Chamfered bearings must be used to clear the journal radius.
An Eagle crankshaft is a great choice for your Mopar big block engine project, whether you are restoring a Mopar muscle car, or building an all out race car, Eagle cranks offer a strong, dependable forged crankshaft, for a stock stroke or stroker engine build up.
We also offer connecting rods, pistons, rings, bearings and complete rotating assemblies, individually tailored to your specific needs. We also offer balancing for an additional charge, if you prefer that the crankshafts or rotating assemblies be balanced before shipping out to you.
