5/16 Magnum Pushrods - 7.750 Long

The COMP CAMS 5/16 Magnum Pushrods – 7.750 Long are precision-engineered valve train components designed for high-performance marine and automotive engines that demand reliability under sustained load. Built from chromoly steel, this set of 16 pushrods serves as the critical mechanical link between your engine's cam and rocker arms, transmitting precise valve timing to ensure optimal combustion and engine efficiency. Whether you're rebuilding a fresh-water fishing boat motor or restoring a performance marine powerplant, quality pushrods are non-negotiable for consistent throttle response and fuel efficiency on the water.

These magnum-duty pushrods feature a 5/16-inch diameter with 0.080-inch thick-wall construction, engineered to withstand the stress cycles of continuous operation without deflection or flex. The 7.750-inch length is precision-manufactured to exact OEM specifications, ensuring zero adjustment hassles during installation and eliminating common cold-start valve noise that plagues inferior components. Chromoly construction provides superior strength-to-weight ratio compared to standard steel, reducing inertial losses and allowing your engine to rev cleaner while maintaining durability in high-RPM marine applications where cam followers and lifter surfaces experience extreme pressure.

Experienced boaters and engine builders select COMP CAMS pushrods for complete cylinder-head rebuild jobs where OEM replacement quality is essential. This full set of 16 covers both intake and exhaust banks on eight-cylinder engines, eliminating the need for piecemeal sourcing. Proper installation requires correct pushrod length verification—measure from the center of the rocker-arm ball socket to the center of the lifter cup to confirm fit before assembly. These pushrods integrate seamlessly with stock rocker geometry and modern hydraulic roller lifter systems, making them ideal for marine engine restorations and performance rebuilds where reliability directly impacts time on the water.
