Push Rods

Push Rods are integral components within an internal combustion engine, serving to transmit the upward motion from the camshaft's lobes to the rocker arms. This precise transfer of linear motion is essential for the proper opening and closing of the engine's valves, directly impacting valve timing and overall engine performance. Understanding the function and characteristics of push rods is key for anyone working with an overhead valve (OHV) or push rod engine.

When selecting push rods for your vehicle's motor push rod system, several factors are important to consider for optimal fit and function. These include the material composition, such as chrome moly or steel, which influences durability and strength. The diameter and wall thickness are also critical, as they affect rigidity and resistance to flexing under stress. Furthermore, the correct length of the pushrod is paramount to ensure proper valvetrain geometry and prevent issues like excessive pre-load or insufficient lift. Many engine builders and enthusiasts search for "pushrod engine" components to maintain or upgrade their valvetrain systems.
