Air Lift's LoadLifter 5000 Ultimate with Air Spring Cradles offers up to 5,000 lbs of load-leveling capacity to help eliminate squat, trailer sway, and body roll. The included Air Spring Cradles allow the air springs to detach from the lower bracket so the suspension keeps full extension travel - which is exactly what you want on a ZR2 or AT4X that actually sees overlanding and off-road use rather than just a trailer hitch.
The internal jounce bumper is what separates the Ultimate from a standard kit: it delivers three-stage ride comfort and zero-PSI safety, so the truck still absorbs impact if air pressure drops. Maintaining ride height under load also improves handling, braking, and steering response, and the maintenance-free air springs are built to perform season after season. Roll plates protect the air springs from abrasion and road debris, and everything needed to install is in the box.
