Speedmaster DNA one-piece pushrods are precision-engineered chromoly components designed for high-performance engine applications. The 6.770" length with 5/16" diameter and 0.080" wall thickness delivers strength and durability in demanding conditions. Heat-treated chromoly construction provides superior rigidity and fatigue resistance, making these pushrods ideal for street and competition engines where reliability and consistent valve actuation are critical.
These one-piece pushrods eliminate the weak points common in multi-piece designs, offering improved durability and consistent performance across a wide range of engine builds. The chromoly material and precision heat treatment ensure these components withstand high RPM operation and aggressive valve train demands. Compatible with standard pushrod-style engine configurations, they serve as direct replacements or upgrades for original equipment on applicable engine platforms.
