3/8in Moly Pushrods - 8.600in Long

The MANLEY 3/8in Moly Pushrods – 8.600in Long (Part No. 25860-8) are precision engine components engineered for high-performance marine and automotive applications requiring strict valve train synchronization. These chromoly steel pushrods feature a 3/8-inch diameter with 0.080-inch thick walls and swedged ends, delivering the rigidity and fatigue resistance demanded by serious builders who rely on consistent cam-to-rocker geometry under sustained rpm conditions. Supplied as a set of eight, these components are sized specifically for engines with 8.600-inch pushrod length specifications.

The moly material composition provides superior strength-to-weight characteristics compared to standard steel, reducing rotating mass while resisting bending and deflection that can accumulate when pushrods transmit repeated loads from camshaft to rocker arms. The swedged ends ensure secure seating in pushrod cups and on rocker studs, eliminating the slippage and misalignment issues that arise from loose connections in tight tolerances. For boat engines running at consistent high rpm or heavy-duty marine duty cycles, this construction minimizes wear patterns and extends component life while maintaining precise valve timing across the entire operating range.

These pushrods serve builders, mechanics, and boat owners restoring or upgrading small-block and mid-block engine platforms where original equipment specifications call for 8.600-inch length. Whether preparing a marine engine rebuild, tuning a performance package, or replacing worn valve train components, the exact fit and materials of these MANLEY pushrods eliminate guesswork and ensure the valve train operates within design parameters. The eight-piece set covers a full small-block engine, making this a complete solution for single-engine builds or as a backup set for serious anglers and boaters who maintain their own powerplants.
