To finish first, you must first finish! All Oliver Racing connecting rods feature our exclusive Parabolic beam designs that offer the highest strength-to-weight ratio. But we Don't stop there. Strength and durability is built into every Oliver Racing connecting rod. We start by using only 100% Made in the USA - American mill certified chromium nickel molybdenum 4340 alloy, meeting AMS2301 cleanliness standards to minimize inclusions. Then each Oliver Racing connecting rod goes through our exclusive two-stage heat treatment manufacturing process optimizing stress relief to provide superior grain structure and ideal grain sizing for maximum strength and durability. And for the ultimate precision and repeatability, we manufacture all Oliver Racing connecting rods in our own state-of-the art climate controlled manufacturing facility (+/- 2 degrees) utilizing Geometric Dimensioning and Tolerance protocols with Zeiss Coordinate Measuring, establishing reliable dimensional control through top-of-the-line software and technology on the production line, requiring each part to be tested against the same three reference points from start to finish. Each Oliver Racing connecting rod includes Custom designed fasteners and Lucas Oil fastener lubrication. Oliver Racing connecting rods—precision, durability and performance you can count on.
