Description
Crankshaft
These PCE cast crankshafts are perfect for mildly built street engines or just to replace stock crankshafts that have seen better days. These PCE crankshafts are precision-ground and micro-polished to exacting tolerances.
Connecting Rods
These PCE I-beam connecting rods incorporate all of the best features possible for an I-beam rod, including some strength adders found in H-beam designs. PCE I-beam connecting rods are profiled with clearance for long stroke applications. These connecting rods feature a one-rib cap design for added strength and bearing support, polished beams to eliminate stress risers. PCE cap screw bolts to greatly increase strength and horsepower capabilities.
PCE 'I' Beam Street connecting rods are manufactured from high quality 5140 chromoly steel. The rods are x-rayed and ultrasonically tested with all surfaces shot peened and stress relieved.
Pistons
Hypereutectic pistons with anti-friction skirt coating are manufactured from a aluminum alloy which contains 16 percent silicon for greater strength and wear resistance. By combining the hypereutectic alloy with the permanent mold process, the piston is strong, lightweight, and thermally-efficient. These pistons run tighter piston-to-wall clearances, improving ring seal and longevity. They are ideal for street, bracket racers and oval track.
