Rocker Arms - Steel

What Are Steel Rocker Arms Used For?

Steel rocker arms play a critical role in the valvetrain of an internal combustion engine. They are responsible for transmitting the motion from the camshaft to the valves, allowing precise opening and closing of the valves for proper combustion. Steel rocker arms are known for their durability and strength, making them a popular choice for high-performance and racing applications. They can withstand high valve spring pressures and maintain their integrity under demanding conditions.

Steel Vs. Aluminum Rocker Arm - Which is Better?

The choice between steel and aluminum rocker arms depends on the specific requirements of the engine and its intended use. Steel rocker arms are favored for their robustness and ability to handle aggressive cam profiles and high valve spring pressures. They are less prone to deflection, making them suitable for high-revving engines. On the other hand, aluminum rocker arms are lighter, which can reduce valvetrain mass and allow for higher RPMs. The decision between the two materials should consider factors such as engine power, RPM range, and budget.

Is a New Steel Rocker Arm Expensive to Replace?

The cost of replacing steel rocker arms can vary based on factors like the brand, quality, and compatibility with your engine. Generally, steel rocker arms are priced competitively, offering a durable and cost-effective solution for improved valvetrain performance. It's recommended to consider the long-term benefits of investing in quality rocker arms that can contribute to better engine performance and reliability.
