Speedmaster DNA 8.400" Chromoly Heat-Treated 3/8" 0.080" Wall One-Piece Pushrods 1-254-029

Speedmaster DNA one-piece pushrods are precision-engineered chromoly components designed for high-performance engine applications. These 8.400" pushrods feature 3/8" outside diameter tubing with 0.080" wall thickness, manufactured from heat-treated chromoly steel for superior strength and durability in demanding engine conditions. The one-piece construction eliminates weak points and ensures consistent valve train geometry for reliable, repeatable performance.

These pushrods are ideal for custom engine builds, racing applications, and high-rpm engine assemblies where lightweight yet rigid valve actuation is critical. The chromoly heat-treatment process enhances fatigue resistance, making them suitable for extended engine run times and high-load scenarios. Commonly used in small-block and stroker engine builds where precision valve timing and reduced flex are essential for optimal combustion and power delivery.
