About GMC Rocker Arm

One of the many internal components in your engine, a GMC rocker arm functions as a lever which works on a valve, and it is moved with a pushrod from the camshaft. The arm takes movement from the camshaft lobe and transposes that motion into the valve so it opens. While one side of the rocker arm is lowered and raised thanks to the rotating camshaft, the other end works the valve. Normally rocker arms are made with a steel type material which is extremely durable, strong and lightweight.
Your GMC engine will run smoothly when the rocker arms are working at full capacity. Rocker arms are generally located inside the engine, near the top and right beneath the valve cover. Replacing your GMC rocker arms is not a very common DIY task, and it is usually only a task for a certified professional mechanic to complete. When you buy a brand new GMC rocker arm to replace a broken or damaged unit, you will be able to have peace of mind knowing that it is the same part that was installed in your vehicle directly off from the assembly line.
