What material are these push rods made from?

These push rods are constructed from 4130 chrome moly tubing. This material is known for its strength and durability, making it a solid choice for engine components that experience significant stress.

What does 'meticulously formed ends' mean for performance?

Meticulously formed ends with exact radii ensure a precise fit against the rocker arms and lifters. This helps maintain consistent contact and stability within the valvetrain, which is important for proper valve operation and engine performance.

What is the purpose of the black oxide finish?

The black oxide finish serves a dual purpose. It provides an added layer of protection against corrosion and wear, and it also helps to reduce friction where the push rod contacts other valvetrain components.

About this part

Product Details

If you're rebuilding the top end of your engine, especially for a performance build or a high-mileage refresh, getting the push rods right is key. These push rods from Manley Performance are made from 4130 chrome moly, a strong and reliable material that holds up well under the stress of engine operation. They're designed to ensure your valvetrain components work together smoothly.

What sets these apart is the attention to detail in their construction. The ends are meticulously formed with exact radii, which helps them seat properly against the rocker arms and lifters. This precise forming, along with excellent concentricity and closely controlled length, means you get a consistent and stable connection throughout your valvetrain. They're also heat-treated and finished with a black oxide coating for added durability and corrosion resistance.

This set includes eight push rods, which is what most common V8 engines require. Having a well-built and precisely manufactured push rod is important for maintaining proper valve timing and lift, ultimately contributing to your engine's overall performance and longevity.
