What material are these push rods made from?

These push rods are made from 4130 chrome moly steel, a strong and durable material commonly used in high-performance engine components. They are also heat-treated and finished with a black oxide coating.

What does 'swedged end' mean for these push rods?

A swedged end means the end of the push rod has been compressed and formed to create a stronger, more precise connection point. Manley Performance forms these ends with exact radii for a proper fit against the lifter and rocker arm.

Are these push rods a direct fit for any specific engine?

This set is designed for general engine component use and requires verification against your specific engine's requirements. Always consult your vehicle's service manual or a qualified mechanic to ensure compatibility before installation.

About this part

Product Details

This set includes sixteen Manley Performance push rods, each measuring 5/16 inches in diameter with a 6.400-inch length and a 0.120-inch wall thickness. They are constructed from 4130 chrome moly steel, a well-known material for its strength and durability in high-stress engine applications. The swedged ends are meticulously formed with exact radii, ensuring a precise fit and smooth operation within your engine's valvetrain.

Manley Performance pays close attention to the details that matter for engine components. These push rods exhibit excellent concentricity, meaning they are perfectly round and balanced, which contributes to reduced valvetrain noise and wear. The closely controlled length ensures that each push rod is consistent, which is critical for proper valve lash adjustment and overall engine performance. They are also heat-treated and finished with a black oxide coating for added strength and corrosion resistance.

When rebuilding or upgrading an engine, the push rods are a vital link in the valvetrain. Using a well-made set like these from Manley Performance helps ensure that your engine's components work together reliably. Always refer to your vehicle's service manual for specific installation procedures and torque specifications.
