3/8in Moly Pushrods - 8.200in Long

The 3/8in Moly Pushrods - 8.200in Long by MANLEY are engineered for high-performance marine and automotive engines where precision valve actuation is non-negotiable. Whether you're rebuilding a saltwater-rated inboard, upgrading an outboard's top end, or restoring a vintage performance engine, these chromoly pushrods deliver the reliability and durability that serious boaters and mechanics demand. Built to exact specifications, they ensure consistent valve timing and lift across the entire RPM range—critical for engines operating under sustained load and exposure.

Each pushrod measures 8.200 inches long with a 3/8-inch diameter and 0.080-inch wall thickness, providing the ideal balance of rigidity and weight for responsive valve control. The chromoly construction resists fatigue and deformation under high heat and cylinder pressure—essential for marine engines where thermal cycling and salt spray accelerate wear. Swedged ends ensure a solid, repeatable contact surface at both the rocker arm and lifter, eliminating slop and maintaining precise geometry. The set of eight pushrods covers a complete valve train, making installation straightforward for full engine rebuilds or selective upper-end upgrades.

These pushrods are ideal for boaters and engine builders working on marine V8s, big-block engines, and performance small-blocks where OEM tolerances have worn or upgraded components demand tighter clearances. Installation requires proper pushrod length verification—measure your existing pushrods or consult your engine's service manual to confirm the 8.200-inch length matches your application. MANLEY's reputation for precision manufacturing makes these a go-to choice among professional marine technicians and experienced DIY builders who refuse to compromise on valve train integrity.
