Speedmaster DNA 8.800" Chromoly Heat-Treated 5/16" One-Piece Pushrods 1-254-023

Speedmaster DNA one-piece pushrods are precision-engineered chromoly pushrods designed for high-performance small-block and big-block engine applications. At 8.800" in length with a 5/16" diameter and 0.080" wall thickness, these heat-treated pushrods deliver durability and reliability under demanding engine operating conditions. The one-piece construction eliminates the weak points found in traditional two-piece designs, providing superior strength and consistent valve train geometry.

These pushrods are ideal for street performance, racing, and restoration builds where valve train precision matters. The chromoly material, combined with heat-treatment and DNA one-piece engineering, ensures minimal flex and maximum control over cam timing. Compatible with most small-block and big-block applications that call for 5/16" diameter pushrods, they're a trusted upgrade for enthusiasts building carbureted or EFI engines that demand reliability.
