5/16 Moly Pushrods - 6.300 Long

The MANLEY 5/16 Moly Pushrods - 6.300 Long are precision-engineered valve train components designed for high-performance marine engine builds. These pushrods deliver reliable valve actuation in demanding applications where consistent lift and durability under sustained RPM are critical. The 6.300-inch length paired with 5/16-inch diameter and 0.080-inch wall thickness creates an optimal balance of strength and weight reduction for performance-oriented builders.

Constructed from chromoly steel with swedged ends, these pushrods provide superior fatigue resistance compared to standard steel alternatives. The swedged design ensures secure seating in rocker arms and lifters, reducing the risk of slippage during high-load cycling. Moly-enhanced chromoly material resists wear and accommodates the thermal cycling that marine engines experience, whether in freshwater or salt-water environments. The 0.080-inch wall thickness offers structural rigidity while maintaining the lighter mass necessary for precise valve timing at elevated engine speeds.

This set of 16 pushrods is ideal for builders upgrading complete valve train assemblies on V8 or large-displacement powerplants. Marine engine builders, offshore fishing boat owners, and performance enthusiasts who demand reliability during extended throttle applications choose MANLEY components for their precision manufacturing and consistent tolerances. Whether assembling a fresh engine or refreshing valve train wear, these pushrods integrate seamlessly with quality rocker systems and cam profiles.

MANLEY has established a reputation for producing valve train components that withstand the demands of professional racing and high-output marine applications. The 5/16 moly pushrod configuration is a proven specification across a wide range of performance builds, offering dependable geometry and material quality that justify their use in engines where reliability cannot be compromised.
