Inflate via easy access air line. Air Lift 1000 Series Air Springs are pressurized air cylinders designed to provide up to 1,000 pounds of additional leveling capacity to heavily loaded vehicles. Designed to work in tandem, the two air springs included in Air Lift's 000 Series Rear Air Spring kit share the duty of supporting your vehicle's rear suspension. Installed within your vehicle's standard coil springs when deflated and malleable, these cylinders can be inflated to up to 50-psi (minimum of 5-psi to avoid chafing and coil pinch) via a series of included air line tubing located by the user at the most convenient spot along the vehicle chassis. Air lines may also be arranged in a dual routing configuration, allowing the the two air springs to be inflated to different pressures if necessary, at different spots selected along the car's chassis. Inflation can be done with any air compression tool capable of delivering the pressure, ranging from a dedicated onboard air compression system, to portable air compression tools built into jump-start tools or even a hand pump. The cylinders are constructed of rugged, durable materials and feature high burst strength.Whether you are experiencing "bottoming out" during which your vehicle nearly scrapes the road and headlight aim is askew, vehicle swaying and rolling due to uneven suspension or a rough ride, the simple answer to the problem could be rear-end suspension adjustment.
