What is the purpose of a pushrod in an engine?

A pushrod is a component in an overhead valve engine that transfers the motion from the camshaft's lifter to the rocker arm. This action, in turn, opens the engine's valves.

Why is the length and diameter of a pushrod important?

Pushrod length is crucial for establishing correct valve train geometry, ensuring the rocker arm contacts the valve stem properly. Diameter and wall thickness affect strength and weight, which can be important in high-performance engines.

What does 'swedged end' mean for these pushrods?

A swedged end means the tube has been compressed and formed to create a stronger, more precise connection point at the tip. This method helps maintain the pushrod's integrity and ensures accurate contact with other valve train components.

About this part

Product Details

If you're rebuilding the top end of your engine, getting the valve train geometry just right is critical for performance and reliability. These Manley Swedged End Chrome Pushrods are designed to help you achieve that precision. They are a key component that connects your camshaft to your rocker arms, and their exact dimensions ensure consistent operation.

Manley has paid close attention to the details with these pushrods. The ends are meticulously formed with exact radii, which helps them seat properly in the rocker arms and lifters. They also boast excellent concentricity and closely controlled lengths, meaning each pushrod in the set is virtually identical. This consistency is important for maintaining proper valve lash and preventing premature wear. The heat treatment and black oxide finish add durability and corrosion resistance.
