5/16in Moly Pushrods - 8.375in Long

The 5/16in Moly Pushrods - 8.375in Long by MANLEY represent a critical internal engine component designed for high-performance marine and automotive applications where valve train reliability and precision matter most. These pushrods serve as the mechanical link between the cam follower and rocker arm, transmitting camshaft motion to open and close engine valves at precisely timed intervals. Built for serious boaters, engine builders, and performance enthusiasts who demand durability under sustained RPM and thermal stress, this set of 16 pushrods ensures complete valve train replacement or upgrade during a full engine rebuild or restoration.

Manufactured from chromoly steel, the 5/16in Moly Pushrods feature a 0.080in thick wall construction and swedged ends, a design that maximizes strength-to-weight ratio while minimizing flex under load. The 8.375in length is engineered for specific engine block geometries, ensuring proper valve lift and duration without binding or excessive side loading on rocker arms. Chromoly's superior fatigue resistance and heat tolerance make it ideal for marine engines operating at continuous throttle, where cast-iron alternatives would fatigue prematurely. The swedged end design provides a secure, low-wear interface with both the pushrod cup and rocker arm socket, reducing valve train noise and wear over thousands of operating hours.

These pushrods are essential for anyone rebuilding a marine or performance engine and serve as direct replacements for original equipment on many small-block and mid-block applications. Set of 16 ensures you have complete coverage for full engine valve trains without partial assemblies. Proper installation requires careful length verification against your specific engine block and rocker arm configuration; consult your engine manual or machine shop to confirm compatibility before ordering. Whether you're restoring a vintage outboard, upgrading an inboard power plant, or rebuilding after catastrophic engine failure, MANLEY's chromoly construction provides the durability needed for years of reliable service on the water.
