These Speedmaster crankshafts are made from the same strong aircraft-quality forging as standard-weight cranks, but have profiled counterweights for less weight. Speedmaster lightweight crankshafts are perfect for engines wanting quicker rpm. These crankshafts feature profiled aero-wing counterweights and have straight shot and chamfered oil holes. Speedmaster crankshafts are nitride-hardened, with large radii on all journals for superior wear resistance, and use lightening holes in all rod throws.
