What material are these push rods made from?

These push rods are constructed from 4130 Chrome Moly steel, a strong and durable material commonly used in performance engine components. They also feature a heat-treated and black oxide finish.

What is the purpose of the swedged end?

The swedged end refers to the way the ends of the push rod are formed. Manley meticulously forms these ends with exact radii to ensure a precise fit and excellent concentricity with the lifters and rocker arms.

Are these push rods suitable for all engine builds?

These push rods are a set of 8, measuring 9.550 inches long with a 0.135-inch wall. They are suitable for engine builds where these specific dimensions and material properties are required for proper valvetrain geometry.

About this part

Product Details

If you're rebuilding the top end of your engine, getting the valvetrain geometry just right is crucial. These push rods from Manley Performance are designed to help you achieve that precision. They connect the rocker arms to the lifters, and their length and diameter are critical for proper valve operation. Getting this right ensures your engine runs smoothly and efficiently.

Manley makes these push rods from 4130 Chrome Moly, a strong and durable material often used in performance applications. They feature a 0.135-inch wall thickness for good rigidity, and each push rod measures 9.550 inches long. The ends are meticulously formed with exact radii, and the manufacturing process ensures excellent concentricity and closely controlled length, which are important for consistent valvetrain action. They also come with a heat-treated and black oxide finish for added protection.
