Less Rotating Weight for More Horsepower!
These crankshafts use the same space-age material as Scat's 9000 Series Stock Replacements yet are modified to be lighter. Pro Comp Lightweight Crankshafts utilize lightening holes and aero-wing counterweights to reduce weight and windage. They're an ideal, affordable option for increasing the cubic inches and horsepower of mild to moderate street or race engines.
