Push Rods

Push rods are essential components in internal combustion engines that play a critical role in the operation of overhead valve (OHV) systems. These slender, tubular rods transmit motion from the camshaft to the engine's rocker arms, ultimately controlling the opening and closing of the engine’s intake and exhaust valves. Made from robust materials like steel or aluminum, push rods are designed to withstand the rigorous stresses of high-performance engines while providing exceptional durability and reliability.

Available in various lengths and diameters, push rods must be correctly matched to specific engine configurations to optimize performance. Builders and mechanics often face decisions regarding stock versus performance push rods, choosing between solid or hydraulic types depending on the application—whether it be standard vehicles, racing, or heavy-duty machinery. Enhanced performance options, such as lightweight or tapered designs, are also available, which can help reduce mass and improve engine responsiveness.

Push rods are not only crucial for power generation but also contribute to the overall efficiency of the engine. Their precise engineering ensures smooth operation and aids in maintaining proper valve timing, which is vital for maximizing horsepower and torque. Additionally, innovations in push rod technology, such as coatings that reduce friction and wear, continue to enhance engine performance and longevity.

In summary, push rods are a fundamental element of engine design, facilitating efficient airflow and combustion while directly influencing engine performance. Whether it’s for a classic restoration project, a modern high-performance build, or replacement parts for routine maintenance, selecting the right push rods is vital for ensuring optimal engine function and longevity. With a wide variety of options available, enthusiasts and professionals alike can find the perfect match for their specific needs.
