What material are these push rods made from?

These push rods are constructed from 4130 chrome moly tubing. This material is known for its strength and is commonly used in performance engine components.

Why is the concentricity and length control important for push rods?

Excellent concentricity and closely controlled length ensure that each push rod makes consistent contact with the lifter and rocker arm. This precision helps maintain proper valvetrain geometry and stability, especially in high-performance engines.

What is the purpose of the swedged ends?

The swedged ends are formed with exact radii. This design helps ensure a solid and consistent contact point with both the lifter and the rocker arm, contributing to efficient power transfer and reduced wear.

About this part

Product Details

If you're rebuilding the top end of your engine, especially for a performance application, getting the valvetrain geometry just right is key. These push rods from Manley are built to help you achieve that precision. They are made from strong 4130 chrome moly tubing, which offers good rigidity to prevent flexing under load. The 0.080-inch wall thickness adds to this solid construction.

Manley pays close attention to the details with these push rods. The ends are meticulously formed with exact radii, and they hold excellent concentricity, meaning they are perfectly round and balanced. This close control over dimensions, including the precise 6.850-inch length, ensures consistent contact with your lifters and rocker arms. They also feature a heat-treated and black oxide finish for durability and corrosion resistance.
