3/8 Hi-Tech Pushrod - 8.280 Long

The 3/8 Hi-Tech Pushrod - 8.280 Long from COMP CAMS is a precision-engineered valve train component designed for high-performance big block Chevy engines. Built for builders and engine builders who demand reliability under extreme RPM and load conditions, this pushrod plays a critical role in accurately transferring camshaft motion to rocker arms with minimal deflection and maximum efficiency. Whether you're assembling a street performance build, race engine, or restoration project, the correct pushrod length and diameter are non-negotiable for proper valve timing and reduced wear.

Manufactured from chromoly steel with a 0.080-inch thick wall, the 3/8 Hi-Tech Pushrod delivers superior strength-to-weight ratio compared to standard pushrods, reducing inertial mass while resisting bending and failure under high-lift, high-duration cam profiles. The 8.280-inch length is precisely engineered to maintain proper rocker arm geometry and valve lash adjustment across the full operating range, preventing binding and ensuring consistent valve lift. Chromoly construction provides exceptional durability in elevated-temperature environments typical of performance and racing applications, while the Hi-Tech designation reflects COMP CAMS' advanced metallurgy and quality control standards that have made the brand an industry standard among serious engine builders.

This pushrod is ideal for big block Chevy platforms (BBC) including 427, 454, and 502 cubic-inch engines, as well as custom stroker combinations requiring precision valve train geometry. Proper installation requires verification of rocker arm stud height, camshaft lobe profile, and intake manifold clearance to ensure the 8.280-inch dimension delivers correct pushrod length for your specific configuration. Installation is straightforward—simply seat the pushrod ball end into the lifter socket and snap the rocker arm end into place—making it a reliable choice for both new builds and pushrod replacements in existing engines.
