3/8in Moly Pushrods - 7.950in Long

The 3/8in Moly Pushrods - 7.950in Long from MANLEY are engineered for high-performance marine engines where reliability under sustained load is non-negotiable. Whether you're running a performance outboard, inboard, or custom freshwater or saltwater rig, pushrods form the critical mechanical link between your camshaft and rocker arms, translating cam motion into valve lift. This set of 8 units ensures you have a complete replacement set for engines requiring multiple pushrods, eliminating the risk of mixing old and new hardware that can lead to uneven valve timing and combustion issues.

Constructed from chromoly (chromium-molybdenum) steel with a 0.080-inch thick wall, these pushrods deliver superior strength-to-weight ratio compared to standard steel alternatives, a critical advantage in marine service where vibration and thermal cycling stress every engine component. The 3/8-inch diameter and 7.950-inch length are precision-manufactured to exacting tolerances, and the swedged ends provide secure, interference-fit seating in both the lifter socket and rocker arm, preventing slippage that could cause valve float at high RPM. Chromoly's inherent ability to resist fatigue and its stable expansion characteristics under temperature fluctuation make it the go-to material for high-revving marine powerplants that endure constant throttle variation and shock loads.

Serious boaters and marine mechanics rely on MANLEY pushrods when restoring or upgrading small-block engines in center consoles, sport-fishing platforms, and performance ski boats. If you're experiencing valve noise, rough idle, or suspect pushrod wear after years on the water, replacing the entire set ensures consistent valve action across all cylinders and restores smooth power delivery. Before installation, verify compatibility with your specific engine block and rocker arm configuration—most modern marine small-blocks use 3/8-inch pushrods, but always confirm length and end type with your engine manual or machine shop to guarantee proper valve geometry and clearance.
