Wabco 415403303R Compressor Assembly

Description

The Wabco 415403303R Compressor Aggregate is a vital component of a vehicle's air suspension system. This assembly provides the compressed air necessary to maintain ride height and support the suspension's functionality, commonly found in trucks and buses. It is a device designed to OE specification, offering robust and reliable performance in demanding conditions. The compressor operates at 12V with a rated current of 35A, generating a maximum operating pressure of 16.0 bar, and features an IP 68 protection class for exceptional durability. Its dimensions are 141 x 152 x 265 mm, and it’s designed to withstand temperatures ranging from -40°C to +80°C, ensuring consistent operation across a wide range of environments.

Key Features & Benefits

This thing basically pumps air into your air springs – those are like big, beefy air – filled cushions instead of traditional metal coil springs. It builds up pressure and maintains it, controlling the height and leveling of your vehicle. It also handles raising and lowering the suspension, if your car has that feature. It's got a motor, a compressor pump itself, and usually a dryer to get moisture out of the air before it reaches the springs. Some have a reservoir tank, too, to store extra air. Think of it as the heart of your air suspension system. It’s what makes everything work. The compressor receives a signal from the vehicle's computer – maybe based on load, speed, or a driver setting – and then it gets to work filling those air springs. It constantly monitors and adjusts the air pressure, keeping your ride smooth and level. It also often plays a part in automatically leveling the vehicle when you’re towing something heavy.

Symptoms, Risks & Replacements

Well, if this thing goes bad, you’ll notice pretty quickly. Your car might start sitting unevenly, ride really rough, or even sag down on one side. You might hear a loud humming or buzzing noise coming from under the vehicle. Often it'll be a gradual decline, but it can fail suddenly too. It’s responsible for a comfortable ride and safe handling, so it's definitely not something to put off getting fixed. You can find a good compressor assembly – and a lot of other suspension parts – over at Fixparts Online if you're looking to do it yourself. They’ve got pretty good diagrams to help you make sure you’re getting the right one. Ignoring problems with the air suspension can also put extra stress on other parts, like your shocks and struts, so it's a good idea to stay on top of it.
