3/8 Hi-Energy Pushrod - 8.280 Long

The 3/8 Hi-Energy Pushrod – 8.280 Long from COMP CAMS is a precision-engineered valve train component designed for serious big block Chevy engine builders and performance enthusiasts. Pushrods are the mechanical link between a camshaft and rocker arms, transferring rotational motion from the cam lobe to valve actuation. The "Hi-Energy" designation indicates this pushrod is built to handle aggressive cam profiles and higher RPM operation without flex or harmonic instability—critical for modified engines running solid or roller lifters with elevated valve spring pressures.

Constructed from hardened steel, this 3/8-inch outer diameter pushrod maintains dimensional precision at 8.280 inches in length to ensure proper rocker arm geometry and valve lash adjustment. The Hi-Energy design minimizes deflection under load, which is essential when working with high-lift cams or when running tighter valve spring rates. Steel construction provides superior durability compared to aluminum alternatives, resisting fatigue and wear over thousands of heat cycles. At just 0.14 lbs, the pushrod's lightweight design reduces inertial loads on the valvetrain, allowing for faster valve transitions and more reliable engagement with both mechanical and hydraulic lifter systems.

This pushrod is ideal for big block Chevy owners undertaking serious engine modifications—from street performance builds to competition engines. Whether you're installing a performance cam, upgrading to a roller lifter setup, or rebuilding after high-mileage use, the 3/8 Hi-Energy Pushrod ensures consistent valve timing and prevents the valve float that can occur with stock or worn pushrods. Installation requires correct length verification and proper rocker arm adjustment; this specific 8.280-inch length is essential for maintaining correct pushrod angle and preload geometry. Sold individually, you'll need a full set of 16 for most big block Chevy applications, making it an economical way to refresh your entire valve train with quality components.
