3/8in Moly Pushrods - 10.100in Long

The MANLEY 3/8in Moly Pushrods - 10.100in Long (MPN 25901-8) are precision-engineered components designed for high-performance marine and automotive engine applications. These chromoly pushrods feature a 3/8-inch diameter with 0.080-inch thick walls and swedged ends, delivering the strength and reliability demanded in serious engine builds where valve train stability directly impacts performance and longevity.

The 10.100-inch length specification suits applications requiring precise valve train geometry and crankshaft-to-rocker arm ratios. Chromoly construction provides superior strength-to-weight characteristics compared to standard steel, reducing inertial loads on valve springs while maintaining rigidity under high RPM operation. The swedged end design ensures secure seating in both rocker arms and pushrod cups, minimizing lateral movement that can compromise valve timing accuracy. This set of eight pushrods delivers the quantity needed for complete small-block engine configurations, making it a practical choice for rebuild projects or comprehensive valve train upgrades.

These MANLEY pushrods serve engine builders, marine technicians, and performance enthusiasts working on V8 platforms where valve train reliability is non-negotiable. Whether restoring a vintage marine powerplant, upgrading a freshwater or offshore fishing vessel, or building a street/competition engine, precision pushrods like these eliminate flexing and harmonics that degrade valve control. Proper pushrod selection—considering length, diameter, material, and end type—is fundamental to maintaining valve timing under load and preventing catastrophic valve train failure during high-RPM operation.
