Speedmaster forged standard weight crankshafts
Speedmaster 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 Rods
Speedmaster 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.
Pistons
Speedmaster Forged pistons are made from 4032 aluminum alloy for quieter operation and reduced piston to wall clearance. Up to 20% lighter than traditional forged pistons that eliminate harmful stress concentrations for superior strength. Specifically designed for naturally aspirated or moderate nitrous applications.
Speedmaster piston rings
Speedmaster piston rings are designed to stand up to the rigor of racing and high-performance street use, while providing a long lasting life. Speedmaster piston rings feature: Plasma-moly coated, barrel-shaped, ductile iron top rings that seal against blow-by when the piston rocks in its bore; tapered secondary rings that seal against the oil control ring's upper surface for excellent oil control; and 3-piece oil rings with stainless steel expanders that provide accurate tension without the loss of any horsepower.
