Speedmaster 7.220" Chromoly Heat-Treated 5/16" 0.080" Wall DNA® One-Piece Pushrods 1-254-008

The Speedmaster 1-254-008 are 7.220" chromoly heat-treated one-piece pushrods engineered for high-performance engine applications. Constructed from durable chromoly steel with a 5/16" diameter and 0.080" wall thickness, these pushrods feature the proprietary DNA® design for reliable valve train operation. The one-piece construction eliminates joint failure points, making them ideal for street performance and racing engines demanding consistent lift and durability.

These pushrods are designed to withstand the demands of modern engine builds where precision valve timing and strength are critical. The chromoly heat-treatment process enhances fatigue resistance and longevity under extreme valve train loads. Compatible with various engine configurations that call for 7.220" length pushrods with 5/16" diameter specifications, these components deliver the performance consistency required in both naturally aspirated and forced-induction applications.
