Signs of Failure

• Vehicle sagging – one or more corners sit lower due to insufficient pressure 

• Noisy or overworking compressor – runs constantly, loud humming/grinding noises, or fails to shut off 

• Suspension warning light – dashboard alert illuminated

• Complete suspension failure – compressor does not activate, loss of ride height adjustment 

💡 The main cause of compressor failure is air leaks elsewhere in the system – inspect air springs and lines for leaks before replacing the compressor . If the compressor is replaced without fixing existing leaks, the new unit will fail prematurely .

Critical – Verify Your VIN Before Ordering

Air suspension compressors are VIN‑, model‑year‑, and system‑type‑specific. VIN cut-offs apply – confirm whether your vehicle requires LR083993 or the superseded LR140034. Provide your VIN – our team confirms exact compatibility before dispatch. We cannot accept returns for misordered parts without VIN verification.

💡 Installation Tip: Professional installation recommended. The relay must be renewed when replacing the compressor – failure to do so will void the warranty . After installation, the suspension system may require calibration using diagnostic equipment.
