What material are these push rods made from?

These push rods are constructed from 4130 Chrome Moly tubing. This material is known for its strength and durability in high-stress applications like engine components.

What does the black oxide finish do?

The black oxide finish is a heat treatment that helps to harden the surface of the push rod. It also provides a degree of protection against corrosion.

Are these push rods suitable for any engine?

These push rods have specific dimensions (7/16" diameter, 8.280" length, 0.165" wall) that are common in many performance V8 applications. It's important to verify these measurements against your engine's specifications to ensure proper fitment.

About this part

Product Details

Starting with 4130 Chrome Moly tubing, these Manley push rods are built for serious engine work. The 0.165-inch wall thickness offers a strong foundation, while the 7/16-inch diameter and 8.280-inch length are common dimensions for many performance V8 applications. The swedged ends are meticulously formed with exact radii, ensuring they seat properly against the lifters and rocker arms without creating stress points.

Manley pays close attention to concentricity and length control during manufacturing. This means each push rod in the set is very similar to the others, which is crucial for consistent valve train geometry. After forming, they are heat-treated and finished with a black oxide coating. This treatment helps harden the surface and offers some protection against corrosion.

This set includes eight push rods, enough for a typical V8 engine. They are a solid option when you're rebuilding your top end and need reliable components for your valvetrain.
