Speedmaster 8.500" Chromoly Heat-Treated One-Piece Pushrods 3/8" 0.080" Wall DNA®

Speedmaster's 8.500" one-piece pushrods are engineered from heat-treated chromoly steel, delivering durability and precision for high-performance small-block engine applications. The 3/8" diameter with 0.080" wall thickness provides a strong, rigid design that resists flexing during aggressive valve actuation, making these DNA® pushrods an ideal choice for street and mild racing builds.

The one-piece construction eliminates press-fit joints, reducing the risk of failure under sustained high RPM operation. Heat treatment enhances strength and fatigue resistance, ensuring reliable performance in demanding engine environments. These pushrods are commonly used in carburetor and fuel-injected small-block builds where consistent, predictable valve timing is critical.
