What material are these push rods made from?

These push rods are constructed from 4130 chrome moly tubing, a material chosen for its strength and durability in engine applications. 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 for the push rod cup or ball. This design helps ensure the end stays securely attached during operation.

Why is concentricity and controlled length important for push rods?

Excellent concentricity and closely controlled length are vital for ensuring consistent valvetrain geometry. This precision helps the engine run smoothly and efficiently by making sure the rocker arms and lifters operate as intended.

About this part

Product Details

If you're rebuilding the top end of your engine, getting the valvetrain geometry just right is key. These push rods from Manley Performance are designed to help you achieve that precision. They connect the rocker arms to the lifters, transferring the motion from the camshaft to open and close your engine's valves. Getting this linkage perfect ensures your engine runs smoothly and efficiently.

Manley builds these push rods from 4130 chrome moly tubing, which is known for its strength and durability. They feature a 0.165-inch wall thickness, giving them solid rigidity to resist bending under the stress of engine operation. The ends are meticulously formed with exact radii, and the set offers excellent concentricity and closely controlled length, which is critical for consistent valvetrain operation. They're also heat-treated and finished with a black oxide coating for added protection.

This set includes eight push rods, enough for a typical V8 engine. Having a matched set ensures all cylinders are operating with the same valvetrain geometry.
