This thing basically takes engine power and turns it into compressed air. It’s a pump, really. It draws in air, squeezes it down into a smaller space, and then stores it at high pressure. It also includes an unloader valve which periodically releases some of that pressure – think of it like letting a little air out of a tire to prevent it from overinflating. It’s constantly working when the engine is running, maintaining the right air pressure in your system. It's the heart of your air brake system. All those air brakes – the ones that stop your vehicle – rely on the pressure this compressor builds. That pressure is what pushes the air into the brake chambers, activating the brakes. It also powers other air – operated components, like the horn or sometimes even auxiliary suspension systems. Without it, you just wouldn't be able to safely and reliably stop. It’s critically important, honestly. The brakes are, obviously, the most vital safety system on any vehicle, but especially on something relying on air brakes. You’ll notice if this compressor is failing. You might experience longer braking distances, the brakes might feel spongy, or you’ll start seeing warning lights come on. A failing compressor means the air pressure drops, and that directly affects your ability to stop. Ignoring it isn’t an option. We carry a good selection of these – you can even find a lot of options over at Fixparts Online if you want to browse. Replacing a worn compressor is a lot cheaper – and certainly safer – than dealing with a brake failure. Reliable engineering: Compressor (MPN 411141103R) includes a 12-month warranty!
