Speedmaster's 8.150" one-piece pushrods are engineered from chromoly steel and heat-treated for durability and strength in demanding engine applications. The 5/16" diameter with 0.080" wall thickness provides a balanced design for reliable valve actuation. DNA® one-piece construction eliminates seams and weak points, delivering consistent performance across high-rev and street engine builds.
These pushrods are ideal for small-block and mid-displacement engine platforms where precision valve timing and durability matter. The chromoly material resists deflection under load, supporting both naturally aspirated and boosted applications. One-piece design ensures zero runout and long service life, making them a trusted choice for engine builders and performance enthusiasts seeking reliable, heat-treated valve train components.
