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.

Diana was excellent on recommending this kit for our Tundra. Easy installation. Makes a significant difference in loads and towing. Talk about fast shipping. Arrived two days sinner than expected, considering we live in the Texas Hill Country an hour away from town 617798

As usual, the service from etrailer.com was great. The installation went pretty well. The instructions were clear and understandable and the installation went as depicted in the instructions. The most difficult part was routing the air lines in safe areas (especially around the exhaust pipe) and then inserting the end into the fitting on the top of the unit since it is nearly impossible to see what you are doing. However, all went well and I had no leaks. Can't wait to get some miles on the truck to see how the ride is with and without the trailer attached. 150325

Work perfect! I installed these on my 2014 tundra to help with hauling a 30’ enclosed trailer when we were moving. Trailer weighed basically my max tow rating for my truck (10500lbs) and with these bags the truck sat perfectly level and towed like a dream! Well the supercharger also helped. 521145

Have them on speed dial for my next travel trailer up grade. Thanks etrailer , job very well done Rou 668884

I compared this product with the Firestone offering for my vehicle and chose AirLift for several reasons: 1- The internal jounce bumpers. I liked the idea of being able to run with little to no air pressure. I also thought this necessary because I needed eliminate the factory bump-stops to install. 2- This product was made in Lansing, MI. I like supporting local industry. 3- I liked the fact that the load from the spring transferred directly into the frame of the truck vs. the offset brackets that came with the Firestone product. I am impressed with and disappointed with this product. We will start with my likes: - The bags do carry the load. I can level the truck regardless of what is in the back or on the trailer hitch. - The towing experience is much better with the bags in the back. The rear springs on the Tundra (probably true of most half ton trucks) for 900# of tongue weight even with weight distribution. The bags eliminated the extreme up/down bounce that come with very stiff weight distribution bars. - The kit is very well engineered and the installation went very well. - Airbags are an excellent compliment to a good WD hitch. My dislikes: - The internal jounce bumpers are awful. IMO they engage way too early. With no pressure in the bags they might as well be steel blocks. The truck crashes into them after only 1.5" of travel (railroad crossings, speed bumps, and undulations in the road. With 5-10 psi in the bags this is better but the stock ride of the truck is gone. It now feels more like a ¾ ton truck in the back (smoother because you are riding on air but there is very little suspension motion). - An airbag acts as a spring when the suspension compresses but it also acts like a spring when the suspension extends. The down travel of the rear suspension is limited. You notice this when you drive through a dip in the road at speed. Not only do I have limited down travel but when the tuck unloads the back of truck runs out of up travel way before the front. I am not sure what the future hold. I love the bags while towing my travel trailer and hate the bags when unloaded. I think that the best option would be a SumoSpring. I did not go this route because most people say that they engage to abruptly and wreck the ride. Well, so do these Airbags. At least with a SumoSpring I would keep the down travel of the suspension. I am considering purchasing a set for evaluation. AirLift offers an unconditional 60 day return policy. However 60 days did not prove to be enough time to really evaluate this product. Right away I noticed the problems with the ride of the truck. I played with air pressure etc. At 90 days I knew what I really didn't like. I wrote AirLift an e-mail but did not receive a response. Would I buy again? Maybe. It is a love/hate relationship. 427052

I have removed the airbags from my vehicle and replaced them with a set of SumoSprings. I am much happier with the SumoSprings.

Installation took about 2 1/2 hrs. on my 2017 Tundra. I thought the instructions were very accurate and easy to follow. I did notice there was no torque spec. for the 3/8 bolts that attached the bottom plate and bowl to the air bag. Other then that everything was straight forward. I'm an old school tech. so I just used a standard USS thread torque chart. I installed these air bags to help stabilize the load when pulling my 32 ft travel trailer. Will be putting them to the test in a couple of weeks on a rather long trip. As for now........5 stars for the installation and etrailers support. 505735


Comments
Lawrence, thank you for your review. The torque spec of the 3/*8 bolt is listed at the bottom of page 7 of the installation instructions. Since these figures are subject to change I cant list them here for liability reasons.

Let me be clear- eTrailer is a great outfit but from my experience with AirLift I recommend eTrailer drop the product line. The AirLift Customer Service is worse than ChiCom support which is 6,000 miles away. 5 or 6 Emails to AirLift over the last couple of months and not a single response. Specifically, in an old AirLift system I bought maybe 10 years ago there was a low-pressure sensor which automatically maintained a minimum 5+ psi in the air-bag system. Going under that pressure voids their warranty. That feature looks to be discontinued in more recent AirLift systems. Maybe a cost cutting effort, and maybe a way to deny warranty claims. Since AirLift doesn't communicate I know nothing for sure. I finally found from other vendors a pressure switch and fitting to install this very important capability and will now begin the install. Buy the more expensive Firestone system. Wish I had. 812185

Thank you for your review. In order to monitor the air pressure in the Air Lift air bags you would need to install an air compressor system in the vehicle that monitors the air pressure and can automatically maintain the minimum air pressure. The Air Lift WirelessAIR Compressor System for Air Helper Springs part AL74000EZ automatically restores air pressure when it falls below a safe pressure. It also allows you to use your smart phone to adjust the pressure.

Installed these air bags in my 2010 Tundra, installation was pretty easy. The only negative with this kit would be the top u shaped clamp bars, the metal is too thin and bend down easily when torqued down. Keep in mind, I’ve only had them installed for a day now.

Air bags work great when the truck is fully loaded but the ride is very brutal when the truck is empty and only 5psig in the bags. The internal bump stops appear to be a little bit to long or stiff. The install was very easy and took less then 2 hours, overall very nice product. 581041

  • 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

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.

  • 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.

  • 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...

  • Troubleshooting Air Bag Suspension System Leaking
    Typically air line leak problems are related to the air line tubing and not the bags them selves. Most commonly the problem is where the air line meets the fitting for the air bag. Not having the cut on the tube totally square causes this problem the most. Try removing the line, re-cutting the line totally square and then reinstalling it. If that doesn't work try spraying everything air bag related with soapy wire to see if you can find where it bubbles as that would be where it is leaking.

  • Will the Air Lift LoadLifter 5000 Fit on a 2010 Toyota Tundra 4x4 with a 5th Wheel Hitch Installed
    The Air Lift LoadLifter 5000 Air Helper Springs, # AL88299, may work with your custom 5th wheel frame brackets, but the fit will depend on how the brackets attach to the frame of your 2010 Toyota Tundra 4x4. The LoadLifter brackets attach to the bottom of the frame and hooks to the inside of the frame and the jounce bumper bracket using clamps (see photo). As long as the brackets for your fifth wheel hitch do not interfere with this location on your vehicle frame, you will have no problem...

  • Rear Suspension Helper Spring Kit for Use with 5th Wheel Hitch in 2018 Toyota Tundra
    Unfortunately you were given correct information. Certain trucks will have compatibility issues between 5th wheel and rear air bag installations. In the case of your 6-1/2-foot bed 2018 Tundra none of the four air bag kits we offer (shown on the linked page) will work along with the hitch's installation brackets. This problem tends to occur more often with shorter truck beds. Although air bags are out other options remain. You could use the SuperSprings Leaf Spring Stabilizer kit...

  • 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.

  • Should Pressure Rating for Suspension Enhancement Air Bag Increase When Load is Put on Trailer
    I spoke with my contact at Air Lift and this is the what they told me: Yes, think of it as a balloon. If you were to sit on it the psi would spike. Always measure the loaded psi while sitting at rest. the pressure will fluctuate as you travel down the road.

  • Will the Air Lift Airbags Part # AL88299 Work with 5th Wheel Frame Brackets on a 2012 Toyota Tundra
    I took a look at the instructions for the Air Lift LoadLifter 5000 Ultimate Air Helper Springs part # AL88299 and compared that to the instructions for the Reese Quick-Install Custom Installation Kit part # RP50084-58. The 5th wheel frame brackets mount on the outside of the frame rail and the airbag brackets mount underneath the frame rail therefore will not interfere with one another. Please keep in mind that they have yet to be tested together but the mounting holes will be clear of...

  • Air Suspension Enhancement System For 2017 Toyota Tundra
    Since the Air lift LoadLifter 5000 Ultimate # AL88299 does not come with a gauge for the cab of your 2017 Tundra, you can use a pressure gauge to check how much pressure you have in the system. If the loads you are carrying will not vary a lot, using a manual gauge would probably work for you. If you want to be able to change the amount of pressure you have in the springs from the comfort of your truck cab or when you are outside, I recommend an air compressor system like part # AL25980....
