What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel. This material is chosen for its good strength-to-weight ratio, making it suitable for engine components that need to be both strong and relatively light.

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

A swedged end means the tube has been compressed and shaped at the end, typically to create a stronger connection point for the push rod cup or ball. This construction method helps ensure the end remains securely attached during operation.

Are these push rods suitable for a performance engine build?

Yes, the 4130 chrome moly construction, precise length control, and heat treatment make these push rods a well-built choice for performance applications where valve train stability is important.

About this part

Product Details

Manley Performance is known for making strong internal engine components, and these push rods are a great example. They're built from 4130 chrome moly, a material chosen for its good strength-to-weight ratio, which is important for keeping your valve train stable at higher RPMs. The 0.080-inch wall thickness offers a solid balance between rigidity and weight.

What sets these apart is the attention to detail in their construction. The ends are meticulously formed with exact radii, and Manley controls the length very closely, ensuring excellent concentricity. This means they'll seat properly and operate smoothly in your engine. They're also heat-treated and finished with a black oxide coating for improved durability and corrosion resistance.

This set includes 16 push rods, enough for most V8 engines. If you're rebuilding your top end or looking for a reliable replacement for your performance build, these Manley push rods are a solid option.
