About this part

Product Details

Manley Performance is well-known for making strong engine components, and these push rods are a great example of that. If you're rebuilding your engine or upgrading your valve train, these push rods are built to handle the job. They're made from 4130 chrome moly, a solid material that offers good strength and durability for the demands of an engine's valvetrain.

What sets these apart is the attention to detail in their construction. The ends are meticulously formed with exact radii, which helps ensure they seat properly against your lifters and rocker arms. You'll also find excellent concentricity and closely controlled lengths, meaning each push rod in the set is very similar to the others. This consistency is important for smooth valve train operation. They're heat treated and finished with a black oxide coating, adding to their overall resilience.
