About this part

Product Details

Manley Performance is well-known for making strong internal engine components, and these push rods are a great example of that. If you're rebuilding your engine's valvetrain, these push rods are built to handle the job. They are made from 4130 chrome moly tubing, which is a solid material for this application, and feature a 0.080 inch wall thickness for good rigidity.

What sets these apart is the attention to detail in their construction. The ends are meticulously formed with exact radii, and they maintain excellent concentricity. This means they'll seat properly in your lifters and rocker arms, ensuring smooth operation. They are also heat-treated and finished with a black oxide coating, which helps with durability and corrosion resistance. The swedged end design is a common feature that helps ensure a secure fit.

This set includes 16 push rods, which is what most V8 engines require. They measure 9.700 inches long and have a 5/16 inch diameter, so make sure these dimensions match your engine's specifications for proper valvetrain geometry.
