What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel, a strong and durable material often used in performance engine components. They are also heat treated and finished with a black oxide coating.

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

A swedged end means the end of the push rod has been compressed and formed to create a stronger, thicker section. This adds reinforcement to the ends, which are critical contact points in the valve train.

Are these push rods suitable for stock or performance engines?

With their 4130 chrome moly construction, precise dimensions, and heat treatment, these push rods are well-suited for both stock replacement and performance engine builds where durability and consistent valve train geometry are important.

About this part

Product Details

If you're rebuilding the top end of your engine, getting the push rods right is crucial for proper valve train geometry and performance. These push rods from Manley Performance are built for engines where precision and strength are key. They measure 7.800 inches long with a 0.080-inch wall thickness, and are made from 4130 chrome moly steel, a well-known material for its good strength-to-weight ratio and durability.

Manley has paid close attention to the details with these push rods. The ends are meticulously formed with exact radii, and they maintain excellent concentricity with closely controlled lengths. This attention to detail helps ensure consistent valve train operation. They're also heat treated and finished with a black oxide coating, which helps with wear resistance and corrosion protection. The swedged ends add extra strength where it's needed most.

This set includes 16 push rods, enough for a typical V8 engine. Having a well-built set of push rods like these is important for ensuring your valvetrain components work together smoothly and reliably over time.
