What is the purpose of a pushrod in an engine?

A pushrod connects the rocker arm to the lifter in an overhead valve engine. It transfers the motion from the camshaft to the valves, controlling the intake and exhaust cycles.

Why are the ends of these pushrods swedged?

The swedged ends are formed with precise radii to ensure excellent concentricity and closely controlled length. This design helps maintain consistent valve train geometry and stability under load.

What does the black oxide finish do?

The black oxide finish provides a layer of corrosion resistance to the pushrod. It also helps the pushrod withstand the heat and stress generated during normal engine operation.

About this part

Product Details

Starting with a .135-inch wall thickness made from 4130 chrome moly steel, these Manley pushrods are built for durability in your engine. The swedged ends are meticulously formed with exact radii, which helps maintain excellent concentricity and closely controlled length. This attention to detail is crucial for consistent valve train operation, especially when you're rebuilding or modifying your engine's top end.

These pushrods are heat-treated and finished with a black oxide coating. This process not only adds a layer of corrosion resistance but also helps ensure the pushrods can handle the stresses of regular engine operation. Because they are sold individually, you can easily replace exactly what you need or build a custom set for your specific application.
