About this part

Product Details

Manley Performance is well-known for making strong engine components, and these push rods are a great example of that. If you're rebuilding or upgrading your engine's valvetrain, these push rods are designed to handle the demands of performance applications. They measure 5/16 inches in diameter and are 8.950 inches long, with a wall thickness of 0.080 inches, making them a solid choice for many builds.

These push rods are constructed from 4130 chrome moly steel, a material chosen for its strength and durability under stress. The ends are meticulously formed with exact radii, and Manley controls the length very closely to ensure excellent concentricity, which is important for consistent valvetrain operation. They've also been heat-treated and finished with a black oxide coating for added protection and a clean look.

This set includes 16 push rods, which is what most V8 engines require. The swedged ends are designed for a secure connection within the valvetrain. When installing, pay attention to ensuring each push rod is seated correctly to maintain proper valve lift and timing.
