5/16 Hi-Tech Pushrods - 8.900 Long

The COMP Cams 5/16 Hi-Tech Pushrods measuring 8.900 inches long are engineered for high-performance marine engine builds where valve train precision and durability under sustained operation matter. These chromoly pushrods deliver the lightweight, rigid construction demanded by boaters and marine mechanics upgrading cylinder head assemblies on performance-tuned powerheads. The set of 16 units covers a complete engine package, eliminating the need for multiple orders during installation or rebuild cycles.

At 5/16-inch diameter with 0.080-inch wall thickness, these pushrods provide the strength-to-weight ratio that marine engines require. Chromoly construction resists fatigue from continuous high-RPM operation while maintaining dimensional stability across temperature swings common in marine duty—particularly in freshwater and offshore environments where engine compartments experience thermal cycling. The 8.900-inch length specification ensures proper geometry for rocker-arm to lifter engagement without shimming or modification, critical for maintaining valve timing accuracy and preventing valve train noise that signals binding or misalignment.

Marine mechanics and weekend boaters rebuilding worn heads or upgrading to higher-lift cam profiles rely on COMP Cams pushrods to complete the valve train without introducing slack or runout. The set of 16 accommodates both 8-cylinder configurations and offers spares for any installation or replacement situation. Whether for inboard V8s, performance outboards, or jet-drive applications, these hi-tech pushrods integrate seamlessly into existing engine architecture while delivering the precision fit that prevents exhaust leaks, misfires, and valve float under load.
