5/16in Moly Pushrods - 8.500in Long

The 5/16in Moly Pushrods - 8.500in Long are precision engine components engineered for high-performance marine and automotive applications where reliability under extreme conditions is non-negotiable. Built by MANLEY, a leader in valvetrain technology, these pushrods deliver the consistent valve actuation that serious boaters and engine builders demand. Whether you're running a rebuilt freshwater fishing boat or a high-output performance engine, these chromoly pushrods ensure your valvetrain operates with zero compromise.

Constructed from chromoly steel with swedged ends, the 5/16in Moly Pushrods feature a 0.080-inch thick wall that provides superior strength-to-weight ratio and resistance to bending under high RPM and extreme load conditions. The molybdenum alloy composition improves fatigue resistance and allows these pushrods to maintain precise valve timing across extended throttle cycles—critical when you're pushing your marine engine to its limits. At 8.500 inches long, they're sized for applications requiring mid-range valvetrain geometry, and the swedged end design ensures secure, consistent seating in rocker arms and lifters without slippage or wear.

Professional engine builders, marine technicians, and performance boaters choose MANLEY pushrods for complete valvetrain overhauls and high-output engine builds where OEM components fall short. This set of 16 units covers a full engine rebuild, ensuring matched geometry across all cylinders for smooth power delivery and reliability. Compatibility depends on your specific engine platform and valvetrain configuration; verify pushrod length and diameter specifications against your engine's requirements before installation to guarantee proper rocker arm geometry and valve clearance.
