Rocker arms are integral components in overhead valve engines, influencing valve actuation and overall engine efficiency. The material choice—steel or aluminum—can significantly affect performance characteristics.

Steel rocker arms typically offer greater durability and resistance to wear, making them suitable for high-performance applications. Conversely, aluminum rocker arms are lighter, which can enhance engine responsiveness and reduce overall weight.

The decision between steel and aluminum rocker arms should consider the specific application and performance requirements, as each material presents distinct advantages and trade-offs in terms of strength, weight, and cost.
