What material are these push rods made from?

These push rods are constructed from 4130 chrome moly tubing. They are also heat-treated and finished with a black oxide coating for added durability.

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

Swedged ends mean the ends of the push rods have been compressed and shaped to create a stronger, more precise contact point. This helps ensure good concentricity and durability where the push rod meets the lifter and rocker arm.

Are these push rods suitable for stock engines?

While these push rods are well-built and feature precise dimensions, they are often used in performance applications where valve train geometry may be altered. It's best to consult with your engine builder or refer to Manley's specific application data to ensure they are the correct length and specification for your particular engine build.

About this part

Product Details

Manley Performance has a solid reputation for building serious engine parts. These push rods, part number 25221-16, are a good example of their attention to detail for performance builds. They measure 7.100 inches long with a 5/16 inch diameter and feature a .120 inch wall thickness, making them suitable for many performance applications where stock push rods might not be long enough or strong enough.

Constructed from 4130 chrome moly tubing, these push rods are heat-treated and finished with a black oxide coating for durability. The ends are meticulously formed with precise radii and exhibit excellent concentricity, meaning they are perfectly centered. This close control over length and end formation is important for consistent valve train geometry, which can affect engine performance and reliability, especially in modified engines. The swedged ends add strength where the push rod contacts the rocker arm and lifter.
