4154033040 Wabco Compressor Aggregate-2Nd Gen.

The Compressor Assembly from Wabco (MPN: 4154033040) is sourced from Germany and has supplier-listed dimensions of 82 x 164 x 1101 mm. It is typically used within the Suspension & Steering > Strut & Spring > Suspension Air Compressor category of automotive replacement parts. Dimensions are provided by the supplier and may include packaging dimensions. Suspension air compressors supply pressurized air to vehicle air springs, maintaining ride height and supporting load leveling. Typically integrated within the vehicle’s chassis near the air spring system, these units utilize a piston or rotary vane design to generate pressures between 150-250 PSI. Components include an electric motor, compressor pump, air reservoir (often integrated), and pressure sensors for system control. Modern units frequently incorporate PWM speed control for noise reduction and efficiency. Failure manifests as sustained ride height drop, compressor run-on, or inability to raise the vehicle.
