What material are these push rods made from?

These push rods are constructed from 4130 chrome moly tubing. This material is chosen for its strength and durability, making it suitable for performance engine applications.

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

A swedged end is a reinforced area where the push rod connects to the lifter and rocker arm. This design helps to strengthen the push rod at these critical points, improving its ability to withstand engine forces.

Are these push rods suitable for all engines?

This set is designed for engines that require push rods with a 7/16" diameter, 8.950" length, and a 0.165" wall thickness. It's important to verify these specifications against your engine's requirements, especially if you have modified components like camshafts or cylinder heads.

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 or upgrading your engine's valvetrain, these push rods are built to handle the demands of performance camshafts and cylinder heads. They are made from 4130 chrome moly tubing, which offers a good balance of strength and weight for reliable operation.

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 with closely controlled lengths. This precision helps ensure consistent valve lift and timing. They're also heat-treated and finished with a black oxide coating for added durability and corrosion resistance. The swedged end design is a common feature that helps reinforce the push rod where it connects to the rocker arm and lifter.

This set includes eight push rods, which is what most common V8 engines require. When installing, make sure to check your specific engine's push rod length requirements to confirm this 8.950" length is correct for your application, especially if you've changed camshafts or cylinder heads.
