Speedmaster 8.550" Chromoly Heat-Treated 5/16" 0.080" Wall One-Piece Pushrods DNA® 1-254-020

The Speedmaster 8.550" Chromoly Heat-Treated One-Piece Pushrods are precision-engineered pushrods designed for high-performance small-block engine applications. Built from chromoly steel and heat-treated for durability, these one-piece pushrods feature a 5/16" diameter with 0.080" wall thickness, delivering the structural integrity and reliability demanded in racing and performance engine builds. The DNA® design optimizes valve train geometry for consistent operation under demanding conditions.

These pushrods are commonly used in street performance, circle-track racing, and marine engine applications where reliable valve actuation and minimal flex are critical. The 8.550" length and chromoly construction make them suitable for applications requiring stronger, lighter-weight pushrods compared to standard steel alternatives. Whether you're building a competition engine or upgrading a street machine, these one-piece DNA® pushrods provide the precision fitment and performance needed for dependable high-RPM operation.
