What material are these push rods made from?

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

Why is push rod length and diameter important?

Push rod length and diameter are critical for establishing correct valve train geometry. Incorrect dimensions can lead to improper valve lift, rocker arm geometry issues, and potential engine damage. These push rods are precisely manufactured to ensure consistent dimensions.

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

A swedged end refers to a manufacturing process where the end of the tube is compressed or flared to create a stronger connection point for the cup that holds oil or contacts the lifter and rocker arm. This method helps ensure durability.

About this part

Product Details

If you're rebuilding the top end of your engine, getting the valve train geometry just right is crucial for reliable performance. These Manley push rods are built from strong 4130 chrome moly tubing, a popular choice for its good strength-to-weight ratio and durability. They feature a 0.120 inch wall thickness, which adds rigidity to help prevent flexing under load, ensuring consistent valve lift and timing.

Manley pays 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 precision helps ensure proper geometry between your lifters, push rods, rocker arms, and valves. They also come heat treated and finished with a black oxide coating for improved corrosion resistance and a clean look.
