5/16 Hi-Tech Pushrods - 7.450 Long

The COMP CAMS 5/16 Hi-Tech Pushrods – 7.450 Long (Part #8407-16) are engineered for high-performance engine builds where precision valve train geometry and durability under sustained RPM demand are non-negotiable. Manufactured from chromoly steel with a 0.105-inch wall thickness, these pushrods deliver the strength-to-weight ratio critical for engines operating at elevated speeds while maintaining consistent valve timing and lift across all eight cylinders in a complete set.

At 7.450 inches long with a 5/16-inch diameter, these Hi-Tech pushrods are designed to work within specific engine geometries and rocker arm configurations. The chromoly construction resists bending and flexing under load, which translates to more accurate valve actuation and reduced noise in the valve train—particularly important in high-revving applications where pushrod deflection can cause valve float and loss of power. The 0.105-inch thick wall balances structural integrity with minimal mass, reducing inertial loading on valve springs and allowing faster valve closure.

This set of 16 pushrods is intended for V8 engine builds where OEM or stock pushrods fall short of performance demands. Builders working on street engines, truck platforms, or racing applications select COMP CAMS Hi-Tech pushrods when upgrading to higher-lift camshafts, increased spring pressures, or sustained throttle applications that expose weaknesses in lighter pushrod designs. Proper length verification against your specific engine block and head combination is essential before installation.
