Speedmaster 1-254-025 9.000" Chromoly Heat-Treated 5/16" 0.080" Wall One-Piece Pushrods

Speedmaster's DNA® one-piece pushrods deliver precision-engineered valve train components built from chromoly steel and heat-treated for durability and performance. These 9.000" pushrods feature a 5/16" diameter with 0.080" wall thickness, designed to transfer consistent motion from lifter to rocker arm in high-performance engine applications. The one-piece construction eliminates joint weak points, providing reliable load transfer and reduced flex during aggressive valve actuation.

Chromoly's superior strength-to-weight ratio makes these pushrods ideal for both street and racing engine builds where consistent lift geometry and reduced deflection are critical. Heat treatment enhances fatigue resistance and longevity under sustained high-RPM operation, ensuring stable valve timing across engine speed ranges. Compatible with standard 5/16" pushrod guideplates and rocker arm studs, they integrate seamlessly into existing valve train assemblies.
