About this part

Product Details

This set includes 16 push rods from Manley Performance, each measuring 5/16 inches in diameter with a 7.950-inch length and a 0.120-inch wall thickness. They are constructed from 4130 Chrome Moly steel, a strong material often used in performance engine components for its balance of strength and weight. The swedged ends are meticulously formed with exact radii, and the push rods themselves exhibit excellent concentricity with closely controlled lengths, ensuring they function reliably within your engine's valvetrain.

The heat treatment and black oxide finish on these push rods help to enhance their durability and resistance to wear. This attention to detail in their construction means they are well-built for consistent performance. When rebuilding or upgrading your engine's top end, reliable push rods are essential for proper valve operation, transferring the motion from the lifters to the rocker arms accurately.
