What material are these push rods made from?

These push rods are constructed from 4130 Chrome Moly tubing. This is a strong and well-known material often used in performance engine components due to its favorable strength-to-weight characteristics.

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

A swedged end means the tubing has been compressed and shaped at the ends. This process strengthens the ends of the push rod, making them more resistant to bending or deforming under the stress of the valve train.

Are these push rods heat-treated?

Yes, these push rods are heat-treated for added strength and durability. They also feature a black oxide finish to help protect against corrosion.

About this part

Product Details

If you're rebuilding the top end of your engine, a solid set of push rods is crucial for proper valve train operation. This set from Manley Performance is built from 4130 Chrome Moly tubing, a strong material known for its good strength-to-weight ratio, making it a popular choice for performance applications. Each push rod measures 5/16 inch in diameter with a 0.120 inch wall thickness and a length of 8.150 inches, designed to work with a wide range of engine builds.

Manley paid close attention to the details with these push rods. They feature meticulously formed ends with exact radii, which helps ensure smooth contact with the rocker arms and lifters. You'll also find excellent concentricity and closely controlled lengths across the set, meaning each push rod is very similar to the others. This consistency is important for predictable valve train geometry. They’ve also been heat-treated and finished with a black oxide coating for added durability and corrosion resistance.

This set includes 16 push rods, enough for most V8 engines. When installing, always refer to your engine's specific service manual for proper procedure and any required clearances.
