What material are these push rods made from?

These push rods are constructed from 4130 Chrome Moly steel, known for its strength and durability. 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 end of the tube has been compressed and formed to create a stronger, more precise connection point for the rocker arm or lifter. Manley forms these with exact radii for excellent concentricity.

Are these push rods suitable for all engine builds?

These push rods have a specific length of 6.875 inches and a 5/16 inch diameter with a 0.080 inch wall. You'll need to verify that these dimensions are correct for your specific engine build and valvetrain geometry.

About this part

Product Details

If you're rebuilding the top end of your engine, getting the valvetrain geometry just right is crucial for performance and longevity. These push rods from Manley Performance are designed to help you achieve that precision. They connect the lifters to the rocker arms, transferring the cam lobe's motion to open and close your engine's valves.

Manley makes these push rods from 4130 Chrome Moly steel, a strong and durable material that resists bending under the stress of high-performance camshafts and valve springs. The 0.080-inch wall thickness adds further rigidity, while the swedged ends are meticulously formed with exact radii for excellent concentricity and closely controlled lengths. This attention to detail ensures consistent operation throughout the entire valvetrain. They're also heat-treated and finished with a black oxide coating for added durability and corrosion resistance.

This set includes 16 push rods, enough for a typical V8 engine. Ensuring you have the correct length and a well-built push rod is key to proper valvetrain function and preventing potential damage.
