5/16in Moly Pushrods - 7.400in Long

The 5/16in Moly Pushrods - 7.400in Long (Set of 16) represent a critical upgrade for engine builders and high-performance mechanics tackling small-block and mid-range engine builds. Pushrods are the mechanical link between a camshaft and rocker arms, transferring cam lobe motion into valve actuation—making their design and material composition essential for reliability under boost, high RPM, and aggressive valve spring pressures. These chromoly units are engineered to withstand the demanding loads of performance, racing, and modified engines where stock pushrods simply cannot deliver the strength or consistency required.

Manufactured from chromoly (chromium-molybdenum alloy), these pushrods offer superior strength-to-weight ratio compared to conventional steel. The 5/16-inch diameter provides the optimal balance of rigidity and reduced mass, critical for minimizing flex and harmonic vibration at elevated engine speeds. The 0.080-inch wall thickness delivers durability without unnecessary weight gain, while the swedged end design ensures secure seating and prevents binding at the rocker arm interface. At 7.400 inches long, this length accommodates popular small-block applications including Chevrolet, Ford, and aftermarket blocks configured for traditional pushrod architecture. The complete set of 16 eliminates the need for multiple purchases and ensures matched pairs throughout your engine.

These chromoly pushrods are ideal for engine builders upgrading to high-lift camshafts, increased valve spring pressures, or higher sustained RPM ranges where stock pushrods risk bending or failure. They are commonly paired with performance rocker arms, adjustable valve covers, and aggressive cam profiles in street performance, track, and competition builds. Proper installation requires careful measurement and clearance verification—most builders recommend confirming pushrod length during final engine assembly to account for block deck height, head gasket thickness, and rocker geometry. Compatible with small-block engines using 7.400-inch pushrods; always cross-reference your specific engine platform and rocker arm configuration before ordering.
