Rocker arms themselves do not add horsepower; they are a component of the valvetrain that helps transfer motion from the camshaft to the valves. However, switching to a high-performance rocker arm with a different ratio can increase valve lift and duration, potentially improving airflow and engine performance, which might result in a modest horsepower gain. The actual increase in horsepower depends on the specific engine setup and other modifications.
