Features to know about
Stay Level and Confident: Up to 5,000 lbs of Load-Leveling Support
Heavy loads can make a truck squat in the rear, throwing off steering and braking. The LoadLifter 5000 air springs provide up to 5,000 lbs of load-leveling support to keep things balanced. With your ride leveled front to rear, handling feels solid, headlight aim stays correct, and braking performance stays steady even with serious weight in the back.
Dial In the Ride You Want: 5 to 100 psi Adjustable Air Pressure
Every haul is different, so being able to fine-tune support matters. These air springs let you adjust pressure anywhere from 5 psi to 100 psi for the right balance between comfort and control. Inflate each spring independently for side-to-side leveling when loads are off-center. Manual inflation valves and air lines are included and can be mounted on the bumper for easy access. Add an optional compressor system later if you want in-cab control.
Built Tough for Real Loads: 2-Ply Reinforced Rubber and Zytel Endcaps
Air Lift uses 2-ply, fabric-reinforced rubber for strength and durability under pressure. The endcaps are made from high-strength Zytel nylon that’s lighter, stronger, and more corrosion resistant than steel. Exclusive upper and lower roll plates help protect the air springs from abrasion and boost load capacity. This design reduces strain on your factory suspension so you can haul heavy cargo without bottoming out or wearing components prematurely.
Smooth and Stable Under Pressure: Full-Time Support That Reduces Sway and Shock
Bouncing, sway, and road shock are common with heavy trailers or uneven loads. These air springs absorb those hits and keep your truck stable over bumps, through curves, and on rough highways. By distributing weight evenly across all four wheels, they help tires wear evenly and steering stay consistent mile after mile.
Straightforward Installation: Mounting Brackets and Hardware Included
The LoadLifter 5000 kit comes ready to install with brackets, hardware, manual valves, and air lines included. Once mounted, you just inflate the springs to the pressure that keeps your truck at normal ride height. It’s a simple way to get full-time load support without complex modifications or downtime.

Note
Service instruction: When servicing your truck with Air Lift air springs installed, if the truck is lifted by the frame, the air must be let out of the springs. And if the rear of the truck is lifted during service, then it must be supported by jack stands to avoid damage to the air springs.
57354 Air Lift LoadLifter 5000 Air Bag Suspension Support System - Back Axle
Install on a 2026 F350 SRW. Love the product and have zero issues with that itself. The reason for the 4 star is the clearance with the factory sway bar and brake lines. It does mention that in the instructions, however it's extremely tight and I'll definitely be checked for rubbing in the future to make sure I don't have clearance issues. Otherwise, they work great paired with the Airlift WirelessAIR compressory system, zero complaints on the usability of the product. 3625665

The installation was not that difficult. I did not use the wire harness bracket supplied, my 2024 F250 I unplugged the harness form the truck sided bracket all the lines run up to and rerouted the harness much cleaner installation3310654

Airlift Bags have performed well, compressor does adjust more at low pressure 10 psi I assume for air temp change, I have checked for leaks multiple time and none found. 6500 towing miles at 80 psi with little auto adjusting pressure and no issues.

Helper Springs are a great assist for the Ford SuperDuty when pulling my 42’ 5th wheel by bringing the truck to normal ride level while driving.
The only issue I have is keeping the slow leak on one side aired up. The leak is at the connector line on top of the bag where the line goes in. I’ve removed, trimmed and reinserted multiple times to ensure it’s secure to no avail. 3544150

That doesn't sound normal, Sid. Have you tried the soapy water method to see if there were any leaks on the bags or the lines at all? I'd definitely try that to see if there are any leaking issues.

Box was re-taped closed and had large gaps. Items inside were scratched and not organized like my previous airlift airbags. Instructions were torn and dirty. Looks like this was a returned item, not new? 3314560
Hey Cory,
Air springs are going to be the best at leveling your F-350 back out once the weight is added but they will most likely affect your unloaded ride quality, even when aired down. That being said, a majority of the unloaded ride quality complaints I've seen have all been on light duty vehicles with less stiff suspensions than your 1-ton Ford so you'd likely not notice the difference nearly as much as others. Air springs would definitely be a top contender for what you're trying... view full answer...
I recommend the Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL29DQ for your 2024 Ford F-350 with the SRW. This is an upgraded spring to the # AL79DQ you found as it has the internal jounce spring. The internal jounce spring helps reduce bouncing which is common with air springs towing loads. It can also help prevent damage to the spring itself should an air line become damaged and loose all the air in the spring.
The Air Lift WirelessAIR Compressor System # AL74000 is my go... view full answer...
Hey Tony! The kits are designed for two different vehicle configurations. The # AL79DQ is designed for single rear wheel trucks and the # AL73DQ is designed to fit the dually. Since that is the only difference between the two you will need to choose based on whether your F-350 is SRW or DRW.
I also recommend adding an air compressor like the Air Lift WirelessONE # AL25980EZ. This will allow you to adjust the air bags no matter where you're towing from the cab of your truck.

Hello Dan,
Definitely on the right road to a smoother ride (pun intended). I would say that you knowing you are on the heavier end of the tongue weight you are safe finding one around the 1k mark. You just want to make sure you are closer to the tongue weight than the trailer weight. I am not sure how much you are looking to spend, but I set up my brother-in-law up with the B&W Continuum Weight Distribution System w/ Sway Control # BW28FR and he has nothing but great things to say about... view full answer...
Hello Tom,
Thanks for writing in and including the pictures.
The issue I am seeing with the Andersen Weight Distribution Hitch # AN69VR is that you have too many things mounted along the A-frame of your Airstream, so there isn't enough room to install the brackets.
Instead, I recommend the Blue Ox SwayPro Weight Distribution Hitch # BLU54TR, along with the Blue Ox Signature Series Lift Brackets # BXW4021. These brackets can bolt directly to the sides of your Airstream's frame, so you... view full answer...
Hey Patrick! For this setup Air Lift will be the way to go. If you have a 2WD you need the # AL57391 and for the 4WD # AL79DQ. Then for an air compressor you can use the Air Lift Load Controller II Compressor System # AL25592.
This is a single path system with a manual gauge. It also has a sensor that automatically kicks on if your air pressure gets too low to protect the air bags. It isn't too fancy but it will do the job and keep you well within budget. If you would prefer a wireless... view full answer...
Hey Greg, yes the Air Lift Air Helper Spring Cradle # AL59DQ that you referenced does fit the Air Lift LoadLifter 5000 Air Helper Springs # AL79DQ that you mentioned as this spring kit is a bellow style of air spring which is what the cradle is designed to fit. view full answer...
Yes, the Air Lift LoadLifter 5000 Air Helper Springs # AL79DQ will fit your 2024 Ford F-250 with the Tremor package. I do recommend stepping up to the Ultimate Springs # AL29DQ as they have the internal jounce bumper. This really helps to cut down on bouncing which typically happens when you have heavy loads and using air bags. It can also help to protect the air bag from getting pinched should an air line rupture while you are driving.

I recommend the Air Lift LoadLifter 5000 Air Helper Springs # AL79DQ for your 2024 Ford F-250. I prefer these as they have the internal jounce bumpers which help to reduce bounce which is a common issue with other air spring manufacturers.
The Air Lift WirelessAIR Compressor System # AL74000 is my favorite compressor system to use with air bags. This system uses a smart manifold which monitors the air pressure for you while you drive. It will automatically make adjustments should the... view full answer...
For your 2023 Ford F-350 4wd dually you will need to select either the Firestone Ride-Rite Red Label Extreme Duty # F95FV or Ride-Rite Air Helper Springs # F35FV. Currently Air Lift only offers kits for models with single rear wheels.
The Air Command Heavy Duty Compressor System # F99VV will allow you to easily adjust the air pressure in the bags from your smartphone using the Ride-Rite app. view full answer...
