PCE forged standard weight crankshafts are designed for street or race engines with substantially increased horsepower. PCE crankshafts are precision-ground, heat-treated, shot-peened, inspected and micro-polished for superior tolerance control. PCE 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
PCE H-beam connecting rods are one of the strongest connecting rods available. PCE H-beam connecting rods are perfect for supercharged and nitrous applications. These rods incorporate a special dowelled cap for specific cap-to-rod alignment and are profiled with extra clearance for stroker applications.

PCE 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.

PCE 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.
