What material are these push rods made from?

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

What does 'swedged end' mean for these push rods?

A swedged end means the end of the push rod has been formed or crimped to create a stronger, more precise connection point. This design, along with the meticulously formed radii, helps ensure proper seating and smooth operation within the valvetrain.

What is the benefit of closely controlled length and concentricity?

Closely controlled length and excellent concentricity are important for ensuring that each push rod functions identically. This consistency helps maintain proper valvetrain geometry across all cylinders, which is crucial for optimal engine performance and reliability.

About this part

Product Details

Manley Performance is well-known for making strong engine components, and these push rods are a good example of that. If you're rebuilding or upgrading your engine's valvetrain, these push rods are built to handle the job. They measure 7/16 inches in diameter with a 0.165-inch wall thickness and are 10.475 inches long, designed to work with many performance engine builds.

These push rods are constructed from 4130 chrome moly steel, a material chosen for its good strength and durability under the stresses of engine operation. The ends are meticulously formed with precise radii, and the overall concentricity is closely controlled. This attention to detail ensures they seat properly and function smoothly within the valvetrain. They are also heat-treated and finished with a black oxide coating for added protection and a clean look.

This set includes eight push rods, which is what most common V8 engines require. Having a well-matched set like this helps ensure consistent valvetrain geometry and performance across all cylinders.
