What material are these pushrods made from?

These pushrods are constructed from 4130 chrome moly tubing, a strong and durable material commonly used in performance engine components. They are also heat-treated and finished with a black oxide coating for added longevity.

What are the key dimensions of these pushrods?

Each pushrod measures 3/8 inch in diameter and 10.350 inches in length. They also feature a substantial 0.135 inch wall thickness, contributing to their strength.

Why is pushrod length and concentricity important?

Precise length and concentricity are vital for proper valvetrain geometry. These factors ensure consistent contact with the lifters and rocker arms, which helps maintain smooth operation and can prevent premature wear on other valvetrain components.
