About this part

Product Details

Manley Performance is well-known for making strong internal engine components, and these push rods are a great example of that. This set is built for engines where precise valve train geometry is key. They measure 5/16 inches in diameter, are 8.500 inches long, and feature a 0.080-inch wall thickness, all made from durable 4130 chrome moly steel.

What sets these apart is the attention to detail in their construction. The ends are meticulously formed with exact radii, and Manley controls the length very closely to ensure excellent concentricity. This means they'll seat properly and operate smoothly in your engine. They're also heat-treated and finished with a black oxide coating, which helps with wear resistance and corrosion protection.

This set includes 16 push rods, which is what most V8 engines require. If you're rebuilding your top end or looking for a solid upgrade for your engine's valvetrain, these Manley push rods are a well-built option.
