CrankshaftSpeedmaster forged standard weight crankshafts are designed for street or race engines with substantially increased horsepower. Speedmaster crankshafts are precision-ground, heat-treated, shot-peened, inspected, and micro-polished for superior tolerance control. Speedmaster crankshafts are also nitride-hardened for superior wear resistance, have straight-shot and chamfered oil holes, and feature lightening holes in all rod throws. These crankshafts also have a large radius on all journals for improved strength and wear resistance.Connecting RodsSpeedmaster H-beam connecting rods are one of the strongest connecting rods available. Speedmaster H-beam connecting rods are perfect for supercharged and nitrous applications. These rods incorporate a special doweled cap for specific cap-to-rod alignment and are profiled with extra clearance for stroker applications.Speedmaster 'H' Beam Street / Strip connecting rods are manufactured from aircraft quality 4340 chromoly steel. The rods are x-rayed and ultrasonically tested with all surfaces shot peened and stress relieved.
