What material are these push rods made from?

These Manley push rods are constructed from 4130 chrome moly steel, known for its strength and durability. They are also heat treated and finished with a black oxide coating.

Why is push rod length important?

Push rod length is critical for establishing the correct geometry in your engine's valvetrain. An incorrect length can lead to improper valve lift, rocker arm geometry issues, and potential damage to other components.

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

A swedged end is a process where the end of the tube is compressed and formed to create a stronger, more precise connection point. For these push rods, it means the ends are meticulously formed with exact radii for accurate contact with lifters and rocker arms.

Product Details

Manley Performance push rods are a solid option when you're rebuilding or upgrading your engine's valvetrain. These push rods measure 5/16 inches in diameter, are 6.500 inches long, and feature a 0.080 inch wall thickness, all constructed from durable 4130 chrome moly steel. They are designed to accurately transfer the motion from your lifters to your rocker arms, ensuring proper valve operation.

What sets these push rods 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 geometry and reliable performance in your engine. They also come heat treated and finished with a black oxide coating for improved durability and corrosion resistance.

This set includes 16 push rods, which is what most V8 engines require. Proper push rod length is critical for correct valvetrain geometry, so always double-check your specific application's needs before ordering.
