Speedmaster DNA one-piece pushrods are precision-engineered chromoly components designed for high-performance engine builds. Built from heat-treated chromoly steel, these pushrods feature a 5/16" diameter shaft with 0.080" wall thickness and an 8.900" length, delivering strength and durability under demanding engine conditions. The one-piece construction eliminates weak points inherent in multi-piece designs, ensuring consistent valve actuation and improved reliability across rev ranges.
DNA pushrods are ideal for street performance, racing, and modified engine applications where durability and precision engineering matter. The chromoly heat-treatment process enhances fatigue resistance, making them suitable for high-lift cams and aggressive valve timing. These pushrods are commonly used in small-block and mid-sized engine builds where reliable valve train operation is critical to performance and longevity.
