This Repair Kit, manufactured by Wabco (MPN 4154039022), is designed for suspension air compressors within suspension and steering systems. It ensures optimal functionality and extends the lifespan of the air suspension system. This kit adheres to OE specifications, guaranteeing a precise fit and reliable performance. Its dimensions are 190 x 210 x 360 mm. This kit basically replaces the internal workings of your air compressor. The compressor itself is a pump, and this kit includes things like new piston rings, seals, a new air filter – all the wear items inside that actually create the compressed air. Sometimes it'll also include the desiccant bag, which helps keep moisture out of the system. It's everything you need to rebuild the compressor instead of buying a whole new unit. Your air compressor is what pumps air into your air springs – those big, rubbery bags that support the weight of your vehicle instead of traditional coil springs. It keeps your ride level, gives you a smooth ride, and a lot of vehicles use it for self – leveling features, like when you’re towing. The compressor gets signals from the vehicle's computer and fills or deflates those air springs as needed to maintain the proper ride height. Well, air compressors do wear out. The piston rings and seals get brittle, the pump itself can lose efficiency, and you’ll notice if it starts to struggle to keep the vehicle at the correct height, especially if you have a heavier load. If it fails completely, you'll likely end up with one or more corners of your vehicle sagging, which affects handling and can damage other suspension components. It’s much cheaper to rebuild the compressor with a kit like this than to replace the whole thing, and you can often find everything you need – including these kits – over at Fixparts Online. It’ll save you a good bit of money and get your ride back to normal. What sets us apart: Repair Kit (MPN 4154039022) includes a 12-month warranty!
