What material are these push rods made from?

These push rods are constructed from 4130 chrome moly tubing, a strong and durable material often used in performance engine components. They are also heat-treated and finished with a black oxide coating.

What is the purpose of the swedged ends?

The swedged ends are designed to create a secure and reliable connection point where the push rod meets the rocker arm and the lifter. This ensures proper contact and efficient transfer of motion within the valve train.

What does 'excellent concentricity' mean for these push rods?

Excellent concentricity means the push rod is very round and uniform along its length. This precise manufacturing helps ensure the push rod seats properly and operates smoothly, contributing to consistent valve train function.

About this part

Product Details

Starting with 4130 chrome moly tubing, these Manley push rods are built for serious engine work. The 0.080 inch wall thickness offers a solid balance of strength and weight, crucial for maintaining valve train stability at higher RPMs. Each push rod measures 8.150 inches long with a 3/8 inch diameter, and features swedged ends for a secure connection to your rocker arms and lifters.

Manley pays close attention to the details that make a difference in the engine bay. You'll find that the ends are meticulously formed with exact radii, and the overall concentricity is excellent. This means they'll seat properly and operate smoothly. They're also heat-treated and finished with a black oxide coating, which helps protect against corrosion and wear during operation. This set includes eight push rods, enough for a typical V8 engine.
