Scat 4-460-4300-6700-220-2 Pro Comp Lightweight 4340 Forged Steel Crankshaft

These Scat crankshafts are made from the same strong aircraft-quality 4340 forging as standard-weight cranks, but have profiled counterweights for less weight. Scat lightweight crankshafts are perfect for engines wanting quicker rpm. These crankshafts feature profiled aero-wing counterweights and have straight shot and chamfered oil holes. Scat crankshafts are nitride-hardened, with large radii on all journals for superior wear resistance, and use lightening holes in all rod throws. Scat cranks are CNC-machined for absolute tolerances and symmetry, offering ease of balance and a reduced rotating weight.
