What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel. This material is chosen for its strength and durability, making it suitable for performance engine applications.

What does 'excellent concentricity' mean for a push rod?

Excellent concentricity means the push rod is very round and consistent along its length. This helps ensure smooth and balanced operation within the valve train, contributing to overall engine reliability.

What is the purpose of the black oxide finish?

The black oxide finish serves a dual purpose. It adds an extra layer of durability to the push rod and also helps to protect it from corrosion, which is important for longevity inside the engine.

About this part

Product Details

If you're rebuilding the top end of your engine, especially for a performance application, you need push rods that can handle the stress. These push rods from Manley Performance are made from 4130 chrome moly steel, a strong material that holds up well under the demands of an engine working harder than stock.

Manley pays close attention to the details with these push rods. The ends are carefully formed with precise radii, and they've got excellent concentricity, meaning they're perfectly round and balanced. This helps ensure consistent valve train operation. They're also heat-treated and finished with a black oxide coating, which adds to their durability and helps prevent corrosion. The swedged end design is a common feature for push rods, providing a solid connection point.

This set includes eight push rods, which is what most V8 engines require. Having push rods that are accurately made and built from strong materials is key to a reliable engine build.
