Mopar Eagle Crankshafts Forged Eagle Cranks Big Block Mopar Eagle
Crankshaft
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.
