Manley Push Rod - 3/8 Dia. - 8.850 Length - 0.135 Wall - 4130 Chrome Moly - Swedged End - Set of 8

This set includes eight Manley Performance push rods, each measuring 3/8 inch in diameter with a length of 8.850 inches and a wall thickness of 0.135 inches. They are constructed from 4130 Chrome Moly steel, a strong and durable material often used in performance engine components. The ends are meticulously formed with exact radii and feature a swedged design, which helps reinforce the ends for better longevity under stress. These push rods also boast excellent concentricity and closely controlled lengths, ensuring they operate smoothly within your engine. They come heat-treated and finished with a black oxide coating for added protection.

The 4130 Chrome Moly construction offers a good balance of strength and weight, making these a solid option for many engine builds. The swedged ends are a notable detail, as they can help prevent the push rod from deforming under the forces exerted by the camshaft and valvetrain. Having precisely controlled lengths and excellent concentricity means each push rod will seat properly and transfer motion efficiently from the lifters to the rocker arms, contributing to consistent valvetrain operation.
