COMP Cams 42140513901 Hi-Tech Chromoly Pushrod Diameter Length Engine Push Rod - 5/16 13.900

The COMP Cams 42140513901 is a Hi-Tech series chromoly pushrod designed for demanding street performance and race engine applications. Built from premium seamless chromoly tubing, this pushrod delivers the strength, rigidity, and valvetrain frequency compatibility required in high-lift, high-RPM engine builds.

Key Features:

• Hi-Tech Series — engineered for hardcore street performance and racing applications
• 5/16" diameter with seamless chromoly construction for maximum strength and durability
• 13.900" gauge length (measured using COMP Cams' .140" gauge diameter standard)
• One-piece design — precision-formed ends provide added thickness in the critical tip area while maintaining constant wall thickness and concentricity
• Heat-treated for compatibility with guide plates and maximum strength
• OD-ground for dimensional consistency
• Black oxide finish with length and part number laser etched on the OD for easy identification

COMP Cams Hi-Tech pushrods are engineered with the understanding that pushrod frequency must match the rest of the valvetrain components and the RPM range of the engine — not just withstand bending loads. This makes them an ideal choice for performance builds where stock or economy-grade pushrods fall short. Compatible with guide plates and pairs well with COMP Cams Magnum and Hi-Tech rocker arms.
