The AirLift LoadLifter 5000 Ultimate Plus is a frame-mounted air spring kit designed to provide up to 5,000 pounds of load leveling capacity. This system features a closed-cell urethane foam jounce bumper inside the air spring to absorb shock and allow the system to be safely operated with zero air pressure.

This product is intended for load support or component replacement only and does not alter factory suspension geometry unless explicitly stated.
