The new Air Lift 1000 HD from Air Lift is a heavy-duty version. Of the air suspension specialist’s debut product, the Air Lift 1000 system. After nearly 70 years, the staple product has been upgraded to offer up to 2,500 lbs. of load-leveling capabilities. Specifically designed for drivers of RAM 1500 pickups, these custom-molded polyurethane air springs are simply inserted. In the rear coil springs, no vehicle modifications are required. Working with the vehicle’s existing suspension, Air Lift 1000 HD does away with many of the problems frequently faced when towing or hauling heavy loads, including squat, poor headlight aim, unresponsive steering, trailer sway, body roll, and bottoming out.
