About this part

Product Details

In this set, you get 16 push rods, each measuring 5/16 inches in diameter with an 8.175-inch length and a 0.080-inch wall thickness. They're constructed from 4130 Chrome Moly steel, a strong material often used in performance applications. The ends are meticulously formed with exact radii, and the push rods themselves show excellent concentricity and closely controlled length, which helps ensure they operate smoothly within your engine.

These push rods are heat treated and finished with a black oxide coating. This treatment process helps improve their overall durability and resistance to wear, which is important for consistent valve train operation, especially in engines that see regular use or higher performance demands. The swedged end design is a common feature that helps with proper seating and alignment.
