5/16 Hi-Tech Pushrod - 7.900 Long

The 5/16 Hi-Tech Pushrod - 7.900 Long from COMP CAMS is a precision valve train component engineered for enthusiasts and mechanics building high-performance engine combinations. Pushrods are the critical mechanical link between a camshaft's lobes and the rocker arms that actuate your cylinder head valves, making their design and durability fundamental to engine reliability and performance.

This model is designed for small-block applications where exact valve lift and timing depend on rigid, consistent pushrod geometry under intense combustion pressure and RPM cycles. COMP CAMS' Hi-Tech series pushrods utilize a 5/16-inch diameter shaft engineered with proprietary alloy steel and precision manufacturing to minimize flex and harmonics at high RPM. The 7.900-inch length is calculated to deliver the correct geometric relationship between cam, rocker, and valve stem, ensuring accurate valve opening profiles and preventing binding during full valve travel.

Hi-Tech construction reduces weight while maintaining rigidity, critical for controlling valve spring oscillation and preventing pushrod failure in builds running aggressive cam profiles or elevated RPM limits. This pushrod fits small-block V8 engines—both Chevrolet and comparable architectures—that use traditional adjustable or solid roller rocker arms with 3/8-inch studs. Verify your engine's exact pushrod length requirement, as even 0.050-inch variance can cause valve clearance issues or rocker geometry misalignment.
