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 high-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 tube has been compressed and shaped at the end, creating a stronger connection point. This design helps prevent failure under the stress of engine operation.

Why is concentricity and controlled length important for push rods?

Excellent concentricity means the push rod is perfectly round and balanced, while closely controlled length ensures consistency. Both are critical for accurate valve timing and lift, which directly impacts engine performance.

About this part

Product Details

Manley Performance is well-known for making strong internal engine components. These push rods, part number 25116-8, are a solid option if you're rebuilding or upgrading your engine's valvetrain. They connect the rocker arms to the lifters, transferring the camshaft's motion to open and close your engine's valves.

Built from 4130 chrome moly steel with a 0.165-inch wall thickness, these push rods are designed for durability. The ends are meticulously formed with exact radii for proper contact with the rocker arms and lifters, and they feature a swedged end for added strength. Manley also controls for excellent concentricity and closely controlled length, which is important for consistent valve timing and lift. They are heat-treated and finished with a black oxide coating to help resist corrosion.
