SBC Magnum Pushrod - 5/16in 7.800in Long

The SBC Magnum Pushrod - 5/16in 7.800in Long from COMP CAMS is an essential valve train component designed for small-block Chevrolet engines running Magnum-style heads. Whether you're building a street engine, weekend cruiser, or performance application, this precision pushrod bridges the gap between your cam and rocker arms with the durability and accuracy that serious engine builders demand. COMP CAMS has engineered this pushrod specifically to handle the demands of modern SBC Magnum platforms, where rocker geometry and valve train geometry require exact length and diameter specifications.

At 7.800 inches long with a 5/16-inch diameter, this pushrod is manufactured to tight tolerances to ensure consistent valve actuation and eliminate unwanted lash variation across your entire valve train. The 5/16-inch diameter is the industry standard for small-block Chevrolet applications and provides the optimal strength-to-weight ratio for high-rpm operation while minimizing inertial losses. COMP CAMS pushrods are precision-engineered and shot-peened for enhanced fatigue resistance, making them capable of handling aggressive cam profiles, higher spring pressures, and demanding RPM ranges without flexing or deflecting under load. The exact 7.800-inch length ensures proper geometry alignment between your cam lobe, lifter, and rocker arm, which is critical for maximizing valve lift and maintaining accurate valve timing.

This pushrod is ideal for engine builders and mechanics working on SBC Magnum-head conversions or original Magnum platform builds where stock pushrods may not meet performance requirements. Installation requires careful verification of your rocker arm geometry—pushrods that are too short will cause excessive rocker arm tilt and accelerated wear, while those too long create binding conditions that kill power and damage valve train components. Always confirm your specific rocker arm brand, lift requirement, and cylinder head configuration before ordering, as pushrod length is critical to engine longevity and performance. The lightweight design (0.13 lbs) keeps reciprocating mass minimal, allowing your engine to rev freely and reducing parasitic losses in high-performance applications.
