What material are these push rods made from?

These push rods are constructed from 4130 Chrome Moly tubing, which is known for its strength and durability in high-stress applications like engine valvetrains.

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

A swedged end means the tubing has been compressed and shaped at the end, creating a stronger, reinforced connection point. This helps prevent failure under the forces exerted by the camshaft and rocker arms.

Are these push rods adjustable in length?

No, these are fixed-length push rods. The length is precisely controlled at 9.550 inches, and it's important to ensure this length is 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. These Manley push rods are designed to help you achieve that precision. They measure 5/16 inches in diameter, are 9.550 inches long, and feature a 0.080-inch wall thickness, all made from strong 4130 Chrome Moly tubing for durability under stress.

What sets these apart is the attention to detail in their construction. The ends are meticulously formed with exact radii, and they maintain excellent concentricity. This means they'll seat properly in your lifters and rocker arms, ensuring smooth operation and consistent lift. The swedged ends add strength where it's needed most, and the heat treatment combined with a black oxide finish helps resist wear and corrosion.

This set includes 16 push rods, enough for most V8 engines. Getting the length right is key for proper valvetrain geometry, so ensure these match your specific application's needs when you're putting your engine back together.
