Ultra-Light Crankshaft
The Crower UltraLight crankshaft redefines the term "light rotating mass" by combining just the right amount of smaller O.D. counterweight with an exclusive lightweight crank pin web area. By lightening the crank pin we are able to CNC excess material from the center of the counterweights without adversely effecting overall balance. Crower pioneered pendulum undercutting the counterweights back in 1989. Approximate weights are 38-43 lbs on
Small Block, 55-60 lbs on
Big Block.
