What Owners Say
Owners and enthusiasts report that the Air Lift 5000 delivers excellent load-leveling capability and straightforward installation, with some completing the job in around five hours. The system performs well for heavy-duty towing applications when aired up. However, a consistent criticism emerges regarding ride quality at minimum pressure—multiple users describe a harsh, truck-like feel at the required 5 PSI baseline, noting every bump becomes noticeable even when not hauling loads. Some suggest the 5000-series may be overly stiff for lighter trucks like 1500s and Tacomas, recommending lower-rated kits for daily driving comfort. Despite the ride quality trade-off, the Air Lift 5000 maintains a strong reputation for durability and effectiveness in serious towing scenarios.
