Hauling a heavy trailer or carrying a full bed load can make your rear end sag and throw off your steering and braking. The LoadLifter 5000 air helper springs provide up to 5,000 lbs of load-leveling support to keep your truck level front to rear. By reducing strain on your factory suspension, they help maintain safe headlight aim, improve handling, and give you a more stable, confident ride every time you tow or haul.
Not every load is the same, and these air bags let you dial in the ride exactly how you want it. With adjustable air pressure from 5 psi to 100 psi, you can pump them up for heavy towing or drop the pressure for a smoother ride when empty. Each spring can be inflated independently for side-to-side leveling when loads are uneven. Manual inflation valves and air lines are included for easy access—typically mounted on the bumper.
The LoadLifter 5000 is built to handle real work. Each air bag uses 2-ply, fabric-reinforced rubber for strength and flexibility, while the endcaps are made from high-strength Zytel nylon that’s lighter, stronger, and more corrosion resistant than steel. Air Lift’s exclusive upper and lower roll plates protect the springs from damage and increase their load capacity, extending the life of your suspension system.
Even with a heavy trailer or camper behind you, these air springs keep things steady. They reduce body sway, absorb road shock, and help your vehicle feel planted over bumps and uneven pavement. You’ll notice better control when braking or steering under load, whether you’re pulling through mountain grades or cruising down the highway.
Everything needed for installation is included—mounting brackets, hardware, manual inflation valves, and air lines. Just mount the springs, inflate them through the valves, and hit the road. The setup works with optional compressor systems (sold separately) if you want in-cab control later on. It’s a straightforward way to get dependable rear suspension support that keeps your truck level and ready for whatever you’re hauling.

Still works great! I am happy with it. I tow a heavy trailer a few times a year and this works very well. I keep a small bicycle tire pump in the truck and it all works great.

Maybe an installation video for your vehicle would be a bit easier to follow:

I still like the product but it seems to have a slow leak somewhere and will not hold air pressure for a week at the original setting. Guess I need to do a bubble leak test, just have not gotten to it. Other than that the product is great.
