When the rear end squats under weight, handling, braking, and headlight aim can all go downhill. The Air Lift LoadLifter 5000 Air Helper Springs add up to 5,000 lbs of load-leveling support to keep your vehicle riding level and stable. By distributing weight evenly across all four wheels, they reduce strain on your factory suspension, improve steering response, and help your tires wear evenly when hauling heavy loads or towing.
Every load is different, and this system makes it easy to dial in the right support. Each air spring can be inflated independently anywhere between 5 psi and 100 psi, letting you fine-tune for front-to-rear or side-to-side leveling. Add air when you’re towing or hauling gear to keep the vehicle steady and drop back down for a smoother ride when unloaded. Manual inflation valves mount conveniently on the bumper for quick pressure adjustments, and an onboard compressor system with in-cab gauges can be added later if you want automatic control.
Under real load conditions, durability matters most. These air springs use 2-ply, fabric-reinforced rubber with high-strength Zytel nylon endcaps that are lighter, stronger, and more corrosion resistant than steel. Air Lift’s exclusive upper and lower roll plates are included to protect the air bags from damage while increasing their load capacity. The kit comes with all necessary brackets, lines, and hardware for installation that holds up to long-term use on tough hauls.
Bumps, sway, and bottoming out aren’t just uncomfortable—they can wear out parts fast. The LoadLifter 5000 design absorbs road shock and reduces sway so your ride stays controlled even on uneven pavement or rough job sites. With the extra cushion of air under load, the suspension stays within its normal travel range for a smoother ride that feels planted and predictable mile after mile.

Works really great no problems installing it or using it
The kit is nice but was missing all the nuts for the u bolts and regular bolts. Would be 5 star if it wasn't missing the hardware
Solid product, as expected. Emily provided excellent customer service!
Great service, Great product .
The air bags work great, we’re pretty easy to install would recommend them highly.
Great customer service always, and delivered on time.
I have a 2011 GMC 2500 HD. Installation was fairly easy; must have patience. Instructions indicated could not use U bolts with fifth wheel hitch. In my case, I found with a little finesse I was able to install the U bolts just fine without having to drill holes in the frame. I have a Reese fifth wheel hitch. So far after pulling my trailer one time it works great.
This is wonderful. Has performed perfectly. I see no need for auto leveling or an onboard air compressor for my use. Just put some in when I’m hauling heavy. I will say the Silverado parking brake relocation bracket could use some more engineering. I had a hell of a time getting the bolt in.
It was as advertised
Took about 3 1/2 hrs to install
I am 70 yrs old and did not have a lift to use
So I am a little slow on the up and downs involved
Fit perfectly
Purchased for my 2019 Silverado 3500HD. I've not had long-term use of it yet, but based on other reviews I anticipate everything will function well for many miles to come.
One thing I wish was included in the package from the manufacturer was the Air Lift Union Tee #21838 which I ended up purchasing separatly. The included air line is fitted with an air valve at each end, requiring you to fill the springs individually. For my use, I wanted a single shared line so the springs remain equal, especially in the event of a leak. I recommend the Air Line brand fitting as I first tried a knockoff version since it was more quickly available, but the entire 5-pack leaked around the o-rings so I had even more downtime (do it right the first time...).
I also have a B&W gooseneck wheel hitch and the instructions call for drilling into the frame and using the self-tapping screws to mount the top plate. I was able to use the U-bolts over my hitch bracket at the rear of the plate, but still had to drill into the frame for the front due to the hitch brackets being higher than the frame rail. It's an awkward angle without having lift access, but still very doable - just a tight fit drilling next to the fuel tank.
Overall, a great solution to improving towing.
These will fit a 2011 chevrolet 2500hd truck. Made my 5th wheel camper feel like I was towing a small utility trailer.
