Speedmaster 7.850" Chromoly Heat-Treated 5/16" 0.080" Wall DNA One-Piece Pushrods 1-254-013

The Speedmaster 7.850" Chromoly Heat-Treated One-Piece Pushrods deliver precision engineering for high-performance engine builds. Manufactured from chromoly steel and heat-treated for durability, these pushrods feature a 5/16" diameter with 0.080" wall thickness and utilize the DNA one-piece design for reliable valve train operation. Ideal for small-block and mid-range displacement engines requiring dependable pushrod geometry and construction.

These one-piece pushrods eliminate weak points associated with two-piece designs, offering consistent performance across a range of engine speeds and load conditions. The chromoly material provides superior strength-to-weight ratio compared to standard steel, making them a preferred choice for street machines, race engines, and high-output builds. Compatible with engines utilizing 5/16" pushrod diameter specifications, they work with both stock and modified valve train configurations where precision pushrod length and wall thickness are critical to camshaft-to-rocker geometry.
