Get the Best of Both Springs

The air springs and jounce springs in this system work together to give you the best ride whether your truck is loaded or unloaded. Air Lift's LoadLifter 5000 Ultimate air springs have internal urethane foam jounces that protect the air springs and provide added ride comfort when your air pressure is low. The jounces also allow you to temporarily carry a load if the air springs lose air pressure. This gives your 3/4- or 1-ton pickup, motor home, or commercial truck air springs that are easier to maintain.


Air Springs Level Your Load

Carrying heavy cargo in your truck bed or trailer puts extra stress on your truck. Your brakes erode faster, your tires wear unevenly, and handling suffers severely. When towing, you might also experience excessive sway, bottoming out, and even inaccurate and unsafe headlight aim.


By pairing your existing suspension with LoadLifter 5000 Ultimate air springs, you can seriously beef up your suspension, ensure equal load distribution, and get the support you need. The springs provide up to 5,000 lbs of load-leveling capacity (depending on the weight-carrying capacity of your vehicle) and distribute the weight of your payload to all 4 wheels. As a result, the stress on your factory suspension is significantly reduced. LoadLifter's air bags are adjustable from 5 to 100 psi for precise support, and they can be inflated equally for front-to-back leveling or independently of one another for side-to-side leveling.


The air springs are made of high-quality, 2-ply, fabric-reinforced rubber. Most air bags lose air at the ends where the bag is enclosed with steel caps. These caps can rust and corrode over time, creating small holes. But the endcaps on Air Lift air bags are fashioned from corrosion-proof Zytel nylon, a material that is both stronger and lighter than steel, ensuring that the air bags won't lose air.


Roll plates on Air Lift 5000 Ultimate air spring

The air bags also have Air Lift's exclusive roll plates, which protect the air springs and beef up their load capacity. These sturdy plates help guard the springs from moving parts under your vehicle that might puncture the air bags. The plates also provide a larger surface area for each spring to roll on. The extra surface area gives you a higher spring rate at a lower air pressure, resulting in a better ride.


Built-In Jounce Springs Add Control and Comfort

Air Lift 5000 Ultimate air spring with jounce spring inside

The closed-cell urethane jounce spring inside each air spring gives you a more stable, comfortable ride. Each jounce acts as an overload spring and engages when your current air pressure level isn't enough to support your load. So on a rough road, the springs will kick in if needed to absorb bumps and shocks and help you to avoid bottoming out. When the jounces support a load, they adjust progressively - the more weight you pile on, the stiffer they become. The urethane material engages more smoothly than rubber jounces so you get a less jerky ride.


Because these jounces are taller than your factory jounce bumpers, they engage sooner than your factory jounces would to provide better support. And if the LoadLifter 5000 Ultimate air springs have insufficient or zero air pressure, the internal jounces will help to temporarily support your suspension and protect it from damage until you can repair or adjust the air spring system.


Easy Installation

This system installs with the included brackets and hardware. Just mount the springs, inflate them, and ride. To inflate the LoadLifter springs, you just have to pump in air through the inflation valves. A line kit is included with the springs so that you can install the manual inflation valves (1 for each spring). These are typically mounted on the bumper but can be installed anywhere that is easily accessible. If you want to make the springs even easier to use, you can get a compressor and gauge system (sold separately) that allows you to monitor and adjust the springs from the cab of your truck.


Lifetime Warranty

Along with a lifetime warranty that has no mileage restrictions, Air Lift offers a 60-day satisfaction guarantee. Just install and use LoadLifter 5000 Ultimate springs for 60 days, and if you are not satisfied at the end of this time, you can remove and return them for a full refund.

  • Recommendation for Fighting Sag When Towing with a 2010 Toyota Tundra and Weight Distribution
    Weight distribution (WD) systems actually take on the weight of any cargo behind the rear axle of the tow vehicle (your 2010 Toyota Tundra) as well as the tongue weight (TW) of the loaded trailer. This is why you are finding that your WD system isn't performing as well when you load down the bed of your pickup. For example, the Equal-i-zer # EQ37100ET has a TW range of 600 lbs - 1,000 lbs. If you were using this system and the 709 lb TW of your trailer plus the cargo behind the rear axle...

  • Finding and Fixing Leaks in an Air Lift Helper Spring System
    First, I have included a link to the installation instructions to the right for Air Lift kit # AL88299 for you. Using soapy water is the best way to find a leak in an air system. If it is leaking at a hose or fitting then replacing that hose or fitting would fix the problem. However if it is a bag that is leaking then you would need to replace the bag. Using the instructions you can reverse the installation process. When cutting air lines the cut needs to be as straight as possible....

  • Air Bag Or SumoSprings For a 2016 Toyota Tundra with 1,600LB Slide In Camper
    I would recommend the Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL88299 over the SumoSprings # SSR-610-47 for your 2016 Toyota Tundra carrying a slide in camper. The Air springs allow you to adjust the air pressure in the springs to dial in your ride quality. And when unloaded you can lower the air pressure down to 5psi which hardly adds any support to the suspension. I prefer to use the Air Lift WirelessAIR Compressor System # AL74000 with the air springs. This allows you...

  • How Much Air Pressure to Use in Airbags While Towing
    I can help but unfortunately, I can't really give you an exact psi to tow your 3,500 lb - 4,000 lb trailer as there are just too many factors that go into selecting the correct air pressure. The most important of which however is ride height. According to the owner's manual for the Air Lift LoadLifter 5000 Ultimate Air Helper Springs part # AL88299, if a load is present then you will need at least 25 psi but will want to continue adding air until the truck is level or you have reached 100...

  • What is the Minimum and Maximum Air Pressure for AirLift Air Bag Kit # AL88299
    No, the minimum air pressure is 5 psi and the maximum is 100 psi. The 40 figure comes into play based off of the instructions which state that generally the system can support 40 pounds per 1 psi of air pressure. I have linked the installation instructions for Air Lift kit # AL88299.

  • Firestone or Air Lift Air Bags for a 2016 Toyota Tundra
    I really like the Firestone airbags because they use a crimp rolled design which is much more durable than the band clamp used with the Air Lift Kit item # AL88299 you were looking at. For your 2016 Toyota Tundra, I recommend the Firestone Ride-Rite Air Helper Springs item # F2445. These air bags have a 4,800 lbs load leveling capacity that will keep your rear end from squatting when you are pulling your horse trailer. I have attached a photo of the crimp roll for you, along with a review...

  • Comparing Firestone and Air Lift Air Bags for 2014 Ford F-250
    The Firestone # F2597 are the air bags I recommend for your 2014 Ford F-250. Firestone quality and durability is far superior to the Air Lift air bags like # AL88395. The Firestone have 4 layers of reinforced rubber and a braided wire girdle which increases burst pressure. By comparison, the Air Lift only has 2-ply fabric reinforced rubber. Firestone also uses a superior anchor system with the rolled crimp seal to keep the air bags secure. The Air Lift may include a jounce spring but that...

  • Comparing Air Lift Loadlifter 5000 and Firestone Ride-Rite Air Helper Springs on 2018 Toyota Tundra
    There are a number of differences between the Firestone Ride-Rite Air Helper Springs # F2445 and Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL88299, starting with fit. While the Air Lift will fit all models of the 2018 Toyota Tundra, the Firestone is only a fit for Tundra's with the TRD package (Toyota Racing Development). The biggest difference, and why I recommend the Air Lift LoadLifter 5000 # AL88299, are that these springs come with internal jounce springs while the Ride...

  • Does Adding An Air Bag Kit Increase My Towing Capacity?
    No, you can not raise your payload capacity by adding an air bag kit. Although adding an air bag kit like the Air lift # AL88388 will go a long way to support your trucks suspension and keep you level when towing, it will not increase your weight carrying capacity. You will still be limited my the manufacturers recommended weight limit. Unfortunately there really is not a way to increase your towing capacity with any kind of aftermarket add-on.

  • Can Air Lift Air Bags be Filled Simultaneously Using a Union Tee
    Yes, you can simultaneously inflate your Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL88299 if you use the Air Lift Union Tee for 1/4" Air Lines # AL21838. This will allow you to fill both bags using a single inflation valve.

  • Which Air Lift Suspension Kit Fits 2005 Toyota Sienna that Has Coil Springs
    We do have Air Lift suspension kits that fit your 2005 Toyota Sienna like the AirLift 1000 kit part # AL60732 but the 5000 series is not a fit for your vehicle due to the coil suspension. This specific kit is for trucks. I attached a picture and install video for this kit on a 2005 Sienna just like yours as well for you to check out. Basically the bag slips between coils of the spring.

  • Can Air Lift Suspension Enhancement Fit 2014 Toyota Tundra with Spacers Under Leaf Springs
    Yes, the Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers # AL88299 will work perfectly fine with the style of lift you have installed on your 2014 Toyota Tundra. This kit attaches to the top of the leaf springs using U-bolts that grab the spring pack so the lift spacer installed under the leaf springs wouldn't be an issue at all. This kit will still support and reduce suspension sag like you are wanting.

  • Best Way to Fight Suspension Sag with a 2015 Toyota Tundra While Towing
    If you are looking for the best way to fight suspension sag on your 2015 Toyota Tundra while towing you actually will want to look into a weight distribution system. Not only does a WD system address the rear end sag due to the tongue weight of your trailer, but it also redistributes some of the tongue weight of the trailer to the front axle which will help with braking and handling. Especially in emergency situations. The best way to pick out a weight distribution system is to base it...

  • Can Air Pressure Be Left in Air Lift LoadLifter 5000 Air Bag Kits

  • Will The B&W 5th Wheel Installation Kit BWRVR3204-00 Fit A 2008 Toyota Tundra With Air Bags?
    Hello Kenneth. The brackets for the B&W 5th Wheel Installation Kit # BWRVR3204-00 will install in the same location as most air bag kit brackets. For example the Air Lift Air Bag kit for the 2008 Tundra, part # AL88299 is not compatible with 5th wheel hitch brackets. I am not sure what band of air bag kit you have but it will likely mean 5th wheel brackets are a no-go. You can always verify this by taking a look at the frame rail to see if any obstructions are present.

    Air bags like the Air Lift LoadLifter 5000 Ultimate Air Helper Springs with Internal Jounce Bumpers # AL88299 can certainly be filled with your boat and boat trailer attached. When setting the air pressure, it is best to load everything and then inflate the air bags to the point where your vehicle is level again.

  • Recommended Air bag Kit For A 2020 Toyota Tundra 4x4
    Hello Sandra, thanks for reaching out. Adding an air bag kit to your 2020 Toyota Tundra 4x4 will definitely help with the sagging. The Air Lift kits are great, but if you want to avoid the integrated jounce bumpers, we do have another option, the Firestone Ride-Rite Air Helper Springs # F2445. This is similar to the Air Lift kit in that they are 5,000 lb rated air bags. The Firestone bags do not have internal bumpers, so you can have a smoother ride when you are not towing. I generally...

  • Comparing the Firestone Ride-Rite Air Springs to the Air Lift LoadLifter 5000 on 2014 Toyota Tundra
    When it comes to quality, the Firestone Ride-Rite Air Helper Springs, # F2445, has a slight edge over the Air Lift LoadLifter 5000 Ultimate Air Helper Springs, # AL88299. Both systems will get the job done, but I would go with the Firestone kit if it were my truck. Firestone has been an industry leader for a long time.

  • How to Determine PSI Needed for Air Bag Kit Suspension Enhancement
    With air bag kits like the Air Lift # AL88299 that you referenced the correct amount of PSI needed is not a number I can give you. You'll need to inflate the bags to whatever pressure allows your tow vehicle to sit level again. There's no way to know number that will be so you'll have to experiment to find the best pressure.

    The Air Lift LoadLifter 5000 Ultimate Air Helper Springs # AL88299 feature air springs that can be adjusted from 5 psi to 100 psi. There isn't a specific inflation level that is recommend for your 13,000 pound 5th Wheel Trailer because it will depend on numerous factors such as the capacity of your truck and the pin weight of the trailer. A truck with a lower capacity will sag more when coupled resulting in the need for more air pressure. The exact weight that you have up at the front...

  • How Much Air Pressure is Needed in Air Bags of Truck with Camper in Truck Bed
    I can only help you pick out the best psi but I can't tell you off-hand exactly the best pressure to use. What you want to do is put in an equal amount of pressure in both bags till the truck is sitting as close to stock ride height as it did before you had the camper installed. That will be your best psi. It's important to use equal pressure on both sides so that your suspension does not act unpredictably.

  • Does 100 PSI Max Rating for Air Lift Air Bags Matter if Loaded or Unloaded
    Actually 100 psi in the Air Lift kit part # AL88299 will be the same amount of air pressure regardless if the truck is loaded or unloaded. It may seem counter-intuitive but air pressure does not change in the bags when a load is put in the truck. If the air pressure did change that would indicate that the bags are being overloaded.
