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.
Procomp Electronics I-beam connecting rods are one of the strongest connecting rods available. Procomp Electronics I-beam connecting rods are perfect for mild street and performance applications up to 450 horsepower. These rods incorporate a special doweled cap for specific cap-to-rod alignment and are profiled with extra clearance for stroker applications.
Procomp Electronics 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.
Procomp Electronics piston rings are designed to stand up to the rigor of racing and high-performance street use, while providing a long lasting life. Procomp Electronics 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.
Main and Rod Bearings
We use only the best in bearings so everyone of our kits includes King Main and Rod Bearings. Why? They use silicon aluminum bi-metal construction. Silicon aluminum is the choice for many of today's engine manufacturers because of its high fatigue strength and superior temperature threshold. Bearing wear is dramatically reduced and the fatigue strength is greatly improved.
