What material are these push rods made from?

These push rods are constructed from 4130 chrome moly steel. This is a strong and durable material commonly used in performance engine components.

What does the 'swedged end' mean?

A swedged end means the tube has been compressed and expanded at the end to create a stronger, thicker wall where it contacts the lifter and rocker arm. This design helps prevent deformation.

Are these push rods suitable for a stock engine rebuild?

Yes, these push rods are well-made and suitable for many engine rebuilds. Their precise dimensions and strong construction ensure reliable operation within the valve train.

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 operation. These push rods from Manley Performance are made from 4130 chrome moly steel, a strong material that holds up well under the stress of engine operation. They feature a 0.135 inch wall thickness, which adds to their rigidity and resistance to bending.

Manley paid close attention to the details with these push rods. The ends are meticulously formed with exact radii, and they maintain excellent concentricity. This means they'll seat properly in the lifters and rocker arms, ensuring smooth and consistent operation. The closely controlled length is also important for setting up your valve train geometry correctly. They come heat treated and with a black oxide finish, which helps with corrosion resistance and provides a clean look.
