They are responsible for opening and closing the engine valves at the right time, allowing fuel and air to enter the combustion chamber and exhaust gases to exit. Made of durable materials such as steel and aluminum, rocker arms come in a variety of shapes and sizes to fit different engine configurations. Properly functioning rocker arms are crucial for engine performance and longevity. If you're looking for reliable and high-quality rocker arms for your car, consider the options available on the market.
