Scat Forged Superlight Crankshafts

These Scat crankshafts are made from the same strong aircraft-quality forging as standard-weight cranks, but have pendulum-cut counterweights to reduce rotating mass and oil windage. Scat Superlight crankshafts are perfect for engines wanting quicker rpm. These crankshafts feature profiled pendulum aero-cut 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.
