5/16 Hi-Energy Pushrods - 9.378 Long

The 5/16 Hi-Energy Pushrods - 9.378 Long from COMP CAMS represent a precision upgrade for serious engine builders and mechanics seeking reliable valve train performance. Pushrods are the mechanical link between your camshaft and rocker arms, transmitting lift and timing commands with zero tolerance for flex or deflection. These 9.378-inch pushrods are engineered for small-block applications where OEM or performance cam profiles demand consistent, repeatable actuation across the entire RPM band. Whether you're restoring a classic V8, tuning a street machine, or building a dedicated race engine, quality pushrods are non-negotiable for longevity and peak cylinder head efficiency.

The 5/16-inch diameter tube construction provides the ideal balance between rigidity and weight, minimizing harmonic vibration that degrades cam lobe contact and rocker arm geometry at high RPM. COMP CAMS' Hi-Energy line uses precision-drawn steel tubing and hardened ball ends, eliminating runout and ensuring consistent oil delivery through the hollow core to upper valve train components. The 9.378-inch length is critical—incorrect pushrod length causes rocker arm geometry misalignment, leading to accelerated wear on valve stems, rocker pads, and cam lobes. These pushrods are manufactured to strict tolerances and are designed to work seamlessly with aftermarket cylinder heads, high-lift camshafts, and aggressive valve spring rates without binding or excessive clearance.

Mechanics and engine builders rely on COMP CAMS pushrods when upgrading to performance cams, changing head heights, or replacing worn valve train components on classic Chevrolet small-blocks and similar displacement engines. Proper pushrod length verification is essential during assembly—measure from rocker arm ball seat to pushrod cup contact surface with components installed. Installation requires careful inspection of rocker arm geometry and rocker stud preload to prevent harmonics that cause premature failure. These pushrods deliver the precision and durability demanded by street machines, circle track racers, and restoration enthusiasts who refuse to compromise on engine reliability and repeatability.
