Rocker arms are typically located between the pushrod and intake and exhaust valves. They are pushed and pulled by pushrods to “rock” up and down, opening and closing the exhaust valve and intake valve of the combustion chamber on engines with a camshaft below the engine. With broken or loose rocker arms, the exhaust valves and intake valves can’t function correctly and the cylinder associated with the faulty rocker arm will be disabled. This will ultimately limit the performance of your engine and your ability to drive the car smoothly and safely. Please carefully compare the pictures or OE numbers to match your original parts before purchasing the product.
