When you’ve got a lot of weight in the bed or a trailer hooked up, the rear end shouldn’t sag. LoadLifter 5000 air springs add up to 5,000 lbs of load-leveling support to keep your vehicle level even when it’s fully loaded. By taking strain off the factory suspension, they help maintain steering and braking performance, protect your tires from uneven wear, and keep headlight aim where it should be. It all adds up to better handling and a safer, more stable ride when towing or hauling.
Every load is different, and these air springs let you dial in exactly the support you need. With adjustable air pressure from 5 psi to 100 psi, you can stiffen them up for heavy loads or let them down for everyday driving comfort. Each bag can be inflated independently through the included manual inflation valves and air lines, so you can also level out uneven loads side to side. You choose how firm or compliant the ride feels while keeping your truck sitting right where it should.
These aren’t lightweight bags meant for showroom trucks—they’re built for hard use. Each spring is made from 2-ply, fabric-reinforced rubber with high-strength Zytel nylon endcaps that are stronger and lighter than steel and won’t corrode over time. Air Lift’s exclusive roll plates protect the springs from damage and increase their load capacity by up to 10 percent. With heavy-duty brackets and hardware included, this setup is made to handle years of hauling without leaks or rust slowing you down.
Hauling heavy cargo doesn’t have to mean a rough ride or bottoming out on bumps. These air springs absorb road shock and reduce sway so the truck feels planted instead of bouncing or wallowing under weight. By sharing the load with your OEM suspension, they cut brake wear, improve handling through curves and dips, and keep your vehicle at normal ride height even when loaded up for long trips or tough jobs.
Installing real load support doesn’t require a shop visit. The kit includes all required mounting brackets, hardware, manual valves, and air lines for a straightforward installation using common tools. Mount the inflation valves in an accessible spot—typically on the bumper—and you’re ready to adjust pressures whenever needed. If you ever want automatic control later, an optional compressor system with in-cab gauges can be added without reworking the setup.
