Speedmaster 1-254-019 Chromoly Pushrods 8.500" Length 5/16" Diameter .080" Wall One-Piece

The Speedmaster 1-254-019 pushrods are engineered for high-performance applications requiring exceptional durability and strength. These one-piece pushrods are precision-manufactured from premium 4130 chromoly steel and heat-treated to withstand the demands of high-lift camshafts and elevated engine speeds.

Key Features:

• 8.500-inch length for precise valve train geometry
• 5/16-inch diameter with .080-inch wall thickness for superior rigidity
• Constructed from 4130 chromoly steel for maximum strength-to-weight ratio
• Heat-treated construction designed for guideplate applications
• One-piece design eliminates weak points found in two-piece pushrods
• Black oxide finish for corrosion resistance and reduced friction
• Engineered to handle high-rpm operation without flexing or failure

These pushrods are ideal for performance engine builds where valve train stability is critical. The thick .080-inch wall ensures minimal deflection under high spring pressures, maintaining consistent valve timing and preventing power loss at high RPM. Compatible with roller rockers and stud-mounted rocker systems when used with guideplates.
