What is the primary function of pushrods in an engine?

Pushrods connect the rocker arms to the lifters in an overhead valve engine. They transfer the motion from the camshaft's lobes to open and close the engine's valves, which is essential for the combustion cycle.

Why is the material and construction of pushrods important?

Pushrods handle significant forces and must maintain their shape under heat and stress. Using strong materials like 4130 chrome moly and ensuring precise dimensions like concentricity and length control helps prevent bending or failure, leading to reliable engine operation.

What does 'swedged end' mean for these pushrods?

A swedged end is a process where the end of the tube is compressed and shaped to create a stronger, more secure connection point. For pushrods, this typically means the ends are reinforced and shaped to mate properly with the rocker arms and lifters.

About this part

Product Details

If you're rebuilding the top end of your engine, especially for a performance application, getting the right pushrods is crucial. These pushrods from Manley are made from 4130 chrome moly, a strong and reliable material for the demands of an engine's valve train. They are 7.550 inches long with a 5/16 inch diameter, and feature swedged ends for a secure connection.

Manley paid close attention to the details with these pushrods. The ends are meticulously formed with exact radii, and the concentricity is excellent, meaning they are perfectly round and balanced. This close control over length and form ensures they will operate smoothly and consistently within your engine. They also come with a heat-treated and black oxide finish, which helps with durability and corrosion resistance.

This set includes 16 pushrods, which is what most V8 engines require. Having a well-matched set like this helps ensure your valve train components work together harmoniously for improved performance and longevity.
