Air Lift air bags, also known as air springs, can improve a truck's handling, stability, and ride comfort, especially when towing or hauling: Stability Air bags can help reduce swaying and shifting, especially in wet or windy conditions. They can also help prevent jack-knifing when braking or turning, which can reduce skidding and fishtailing. Load-leveling Depending on the kit, air bags can help keep trailers stable and level by adding hundreds or thousands of pounds of assistance. Ride comfort Air bags can help improve ride comfort by reducing spring sag and increasing rear ride height. They can also help with bumps in the road. Braking and steering Air bags can provide better braking and steering control, which can be especially helpful when towing or hauling
