RPM cast crankshafts are designed as a better than stock nodular iron OE replacement for domestic applications. Strong castings
and a large selection of stroke and rod combinations make these cranks ideal for the street/strip racer.

We sell cast cranks from both Eagle, RPM, and Ohio Crankshaft.
These crankshafts are new cast pieces made with modern material and
casting processes to be a great alternative to 30 year old factory cranks.
Many factory cranks we check have stress cracks, so even though your
crank has not broken yet, you may have a problem developing that could
destroy your engine.

Racing Parts Maximum (RPM) was established in Southern California in
1998. Regarded as an innovative pioneer, RPM has won the admiration and
confidence of many engine builders due to the premium quality and design of
our products while allowing competitive prices. The need for superior
products prompted us to increase our product lines on Crankshafts and
Connecting Rods.
