When you’re towing a big trailer or hauling a heavy load, the rear end can squat hard. The LoadLifter 5000 air springs add up to 5,000 lbs of rear axle support to keep your truck level and balanced. That means safer handling, better braking performance, and even tire wear. By taking the strain off your factory suspension, these air springs help your vehicle ride steady and maintain proper headlight aim when loaded down.
Every load is different, so being able to tune your setup matters. Each LoadLifter 5000 spring can be manually inflated between 5 psi and 100 psi for the support you need. Inflate both evenly for towing or adjust them independently for side-to-side leveling when hauling uneven cargo. Manual inflation valves and air lines are included, and a compressor system with in-cab gauges can be added later for easy adjustments.
These springs are built to hold up under serious work. The bags use 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. Upper and lower roll plates protect the bags from damage and increase load capacity. That kind of construction means less worry about leaks or corrosion down the road.
Hauling or towing doesn’t have to mean a rough ride. The air springs absorb bumps, sway, and road shock so your truck feels more stable over uneven pavement or when passing trucks on the highway. With proper inflation, you get a smoother ride loaded or lightly packed—without bottoming out or bouncing down the road.
You don’t need a full shop to install these springs. The LoadLifter 5000 comes with mounting brackets, hardware, manual valves, and air lines—everything you need to bolt it on and get rolling. Once mounted, just set your air pressure through the inflation valves on the bumper, dial it in for your load, and hit the road knowing your suspension is ready to handle whatever’s in the bed or behind the hitch.

The air bags look great, James! Seeing all the different angles really helps see what they look like on. Thanks for sharing all those pics!

You mentioned that you were experiencing minor air leaks. The easiest to see where the leak is coming from is to use a spray bottle with soap water to spray each fitting to see which is leaking. Once you have found it remove the air line and re cut it. Make sure to get a very straight even cut. An angled or crooked cut will cause leaking every time. Then place it back in and retest.

The Air Lift system is still performing as expected. The minor air leak was resolved. Under load the system provides a stable ride. When not under a load the ride is a little rougher...I just have to remember it is a 34 ton truck. Yes, I would still recommend the Air Lift system.

I love the air bags for hauling our 5th wheel RV. Our truck used to squat some but now I run with about 80 lbs and brings truck back to standard height just have to remember to let some air out when unhooked from trailer or ride is a little stiff

Glad to hear you are still liking them, Zach! Are the picture you sent in before or after the bags were installed? If it's after, I think you could actually go with a little higher pressure to really level out!
