Carrillo Pro-SA connecting rods cover the middle ground between their Pro-H and Pro-A rods. Super A-beams have an increased beam thickness to handle higher load capacities than the regular A-beam rods and are built to the same stringent tolerances as the Pro-H rods. Crafted from robust steel that's forged, heat-treated, shot-peened, and inspected through the entire manufacturing process, these rods are highly effective. Select materials, high-tech design, and rigorous testing make Carrillo Pro-SA connecting rods proven winners and your connection to victory lane
