Rear-end squat throws off your handling and headlight aim when you’re towing or hauling. The Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers provide up to 5,000 lbs of load-leveling capacity to keep things level and stable front to back. By sharing the load across all four wheels, they help maintain safe braking and steering while preventing bottoming out under heavy tongue weight or bed cargo.
Rough roads and uneven loads don’t stand a chance against the hybrid spring setup in this system. Inside each air bag is a closed-cell urethane jounce spring that engages progressively as the weight increases. It cushions road shock, cuts down on sway, and adds stability when cornering. Even if air pressure runs low, the internal jounces pick up the slack to help protect your suspension from harsh impacts.
No two hauls are the same, so the adjustable air springs let you fine-tune your setup for every job. Add air pressure when towing or carrying heavy loads for maximum support, or drop it closer to the 5 psi minimum when cruising unloaded for a softer feel. Manual inflation valves and air lines are included for simple setup, and independent adjustment lets you level side-to-side when loads aren’t centered.
Each LoadLifter 5000 Ultimate spring is built with 2-ply, fabric-reinforced rubber for durability and long service life. High-strength Zytel nylon endcaps resist corrosion and weigh less than steel without sacrificing strength. Air Lift’s exclusive upper and lower roll plates guard against punctures from moving parts and increase surface area for better ride quality at lower pressures. Urethane internal jounces require no maintenance, working reliably through hot and cold conditions.
Everything needed for installation comes in the box—mounting brackets, hardware, manual valves, and air lines. The setup mounts directly to your existing suspension with basic tools, making it a solid option for DIY installation. Once installed, simply inflate through the accessible valves on your bumper or pair it with a compatible onboard compressor system (sold separately) for in-cab control and on-the-fly adjustments.

I reached out to the manufacturer about the leak that you are experiencing. They advised that they had sent out new elbow fittings to help to fix the leak. If you are still experiencing leaks please let us know.

Hey Carey! I couldn't agree more, Cammi is a one-of-a-kind rock star.

Ok. I have had air bags on 4 trucks. They all leak air so it’s common to ad air monthly. Make sure to use the plumbers tape on threads.

Glad to hear the install went smoothly! Thanks for the suggestion on the brake line/ABS brackets too. Definitely something that could make a good kit even better!

Product works great and helps level the truck during towing. I have noticed a difference in the amount of travel my back wheels have when offloading. But I knew that would be a sacrifice.

The air lift system is still working perfectly. Holds air pressure with no leakage. Thousands of miles towing fifth wheel doing what it was designed to do - carry the extra load.
