Crankshaft Procomp Electronics cast crankshafts are perfect for mildly built street engines or just to replace stock crankshafts that have seen better days. These Procomp Electronics crankshafts are precision-ground and micro-polished to exacting tolerances. Connecting Rods Procomp Electronics 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. Procomp Electronics 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. Procomp Electronics cap screw bolts to greatly increase strength and horsepower capabilities. Procomp Electronics 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.
