What material are these pushrods made from?

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

What does 'swedged end' mean for these pushrods?

A swedged end means the tube has been compressed and formed to create a stronger, more precise radius at the end. This helps ensure a good fit and reliable contact with the rocker arms and lifters.

Are these pushrods a direct replacement for all engines?

These pushrods have a specific length of 7.625 inches and a diameter of 5/16 inches. Engine valve train geometry is critical, so it's important to verify this exact length and diameter are correct for your specific engine build before installation.

About this part

Product Details

In this set, you get sixteen Manley 7.625-inch long, 5/16-inch diameter pushrods made from 4130 chrome moly steel. These are essential components for your engine's valve train, connecting the rocker arms to the lifters. Getting the length and geometry just right is critical for proper valve operation and overall engine performance.

Manley has paid close attention to the details with these pushrods. The ends are meticulously formed with exact radii, which helps ensure they seat properly in the rocker arms and lifters. You'll also find excellent concentricity, meaning the walls are consistently thick around the entire pushrod, and the length is closely controlled from one pushrod to the next. This precision is important for maintaining consistent valve lash and preventing issues like valve float or improper valve lift. They’ve also been heat-treated and finished with a black oxide coating for improved durability and corrosion resistance.
