What material are these push rods made from?

These push rods are constructed from 4130 chrome moly tubing, which is known for its strength and durability in engine components. They are also heat treated and finished with a black oxide coating.

Why is push rod length so important?

Push rod length is critical for setting up your valve train correctly. It directly affects rocker arm geometry and lifter preload, which are essential for consistent engine performance and longevity.

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

A swedged end typically refers to a method of joining or shaping the end of the tube, often creating a stronger or more precisely formed contact point for the lifter or rocker arm.

About this part

Product Details

Manley Performance is well-known for making strong internal engine components. These push rods, part number 25863-8, are a good example of their focus on precision. They are designed for engines where precise valve train geometry is important, helping to ensure consistent performance and durability.

Built from 4130 chrome moly tubing, these push rods have a wall thickness of 0.080 inches and a length of 8.625 inches. The ends are meticulously formed with exact radii, and the swedged end design is common in many performance applications. Manley controls the length very closely, which is critical for setting up your valve train correctly. They are also heat treated and finished with a black oxide coating for added durability and corrosion resistance.

This set includes eight push rods, which is what most V8 engines require. Proper push rod length is essential for correct rocker arm geometry and lifter preload, so using a well-made part like this can make a difference in how your engine runs and how long it lasts.
