When the trailer tongue or bed load starts to weigh your rear end down, these LoadLifter 5000 Ultimate air springs step in with up to 5,000 lbs of load-leveling capacity. They keep your vehicle level front to back so your handling, braking, and headlight aim stay consistent under load. By taking stress off your factory suspension, they help distribute weight evenly across all four wheels so your truck feels stable even when towing heavy or hauling uneven weight.

Rough roads or uneven loads don’t have to mean a harsh ride. Each air bag has a closed-cell urethane jounce spring inside that engages when air pressure alone isn’t enough to support the load. These internal jounces absorb bumps and road shock, reduce sway, and help with cornering. They also act as a built-in fail-safe if you ever lose air pressure, keeping your suspension protected and your ride controlled until you can refill the bags.

Every haul is different, so being able to dial in your support matters. These air springs adjust anywhere from 5 psi to 100 psi so you can tune the firmness for what you’re carrying. Inflate both sides evenly for front-to-back leveling or adjust each one separately for side-to-side balance on off-center loads. Manual inflation valves and air lines are included and can be mounted on the bumper for easy access.
The LoadLifter 5000 Ultimate system is built from durable materials designed for long life under heavy-duty use. Each 2-ply, fabric-reinforced rubber air spring includes Air Lift’s exclusive upper and lower roll plates that protect against damage and extend spring life. The high-strength Zytel nylon endcaps are lighter, stronger, and more corrosion resistant than steel, and the urethane internal jounces require no maintenance in hot or cold conditions. With sturdy brackets and hardware included, this setup is ready for real-world hauling without compromise.

Hi, everybody, Andy here with etrailer.com. Let's take a look together at these Air Lift LoadLifter 5000 Ultimate Air Helper Springs with internal jounce bumpers for your rear axle. Now, these have been designed to fit your 2017 to 2020 Ford F-150 Raptor. And on custom-fit parts such as these springs, I do recommend taking advantage of our vehicle fit guide here at etrailer.com. Input the year, make and model of your vehicle and our fit guide will confirm if these will work for you or if we have something comparable that will work for you. Now, this hybrid spring system with a load leveling capacity of 5,000 pounds combines the adjustability of air springs with the reliability of jounce-style springs.
These air springs are going to reduce the strain on your rear suspension, it's going to increase safety, and compensate for uneven loads. Now, some additional benefits include leveling your truck, front to back, and help maintain that safe headlight aim. They'll adjust independently for side to side leveling of any off center loads, which will improve steering and braking performance. Now, on the inside of each of these air springs are jounce springs. They help improve ride comfort, reduce sway, and help with cornering.
It will engage a lower air pressures to better absorb road shock and minimize bottoming out, and it's going to provide support progressively, which means the more you load the springs, the stiffer they become, and it'll let you temporarily carry a load with zero air pressure in the air springs because of those jounce springs inside. Now, these are made here in the USA of 2 Ply fabric reinforced rubber, and these airbags have air lifts exclusive upper and lower roll plates. So these plates are going to protect the air springs from damage and they're going to extend the life of your suspension system. The adjustable air pressure on the air spring is from five PSI to 100 PSI. And on the end of each spring, and you're not gonna be able to see it because I do have these kind of loosely put together to kind of give you an idea of how these are going to attach to these brackets.
But on the end of each spring, it's a high strength Zytel nylon end cap, which is lighter, stronger, and more corrosion-resistant than steel. The jounce spring that's on the inside is a urethane jounce spring, so it requires no maintenance and it works well in hot or cold temperatures. So this kit includes everything that you see laid out here on my table before me. Of course, you're going to get the mounting brackets and all the hardware that you're going to need to install these. And then the manual inflation valves and the air lines are included, the manual valves are typically mounted on the bumper for easy access.
You are gonna get a set of instructions to guide you through the installation process. And you can get compressor systems with in-cab gauges that can be added to monitor and automatically adjust the air pressure. Those items, we do sell separately here at etrailer.com and you can find them under the related product section on this product page as well. Now, again, I said at the beginning of our time together that the load leveling capacity is up to 5,000 pounds. But it is important to note that these air helper springs do not actually increase your F-150 rafters weight carrying capacity. So you do wanna make sure that you're not exceeding Ford's recommended weight limit. Well, that's gonna wrap up our quick look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.

Glad to hear the install went smoothly! Thanks for the suggestion on the brake line/ABS brackets too. Definitely something that could make a good kit even better!

Happy to hear these are getting the job done! Your set up looks great, and man! What a beautiful picture. Blue, sunny skies, green grass, a cool breeze (I'd wager) perfect day to hitch up the trailer and get some work done!

Been great! I really don’t like the internal jounce stops though. When you are unloaded and running lower bag pressure, a dip or bump will hit the bump stops really hard and jar your passengers in the backseat. It’s almost too uncomfortable to ride in the backseat now. As for the loaded and high pressure performance it’s great! Great handling and no sag at all when towing.

Install looks fantastic Lloyd! Glad to hear they helped with the side to side movement. What kind of trailer are you going to be towing with the new set-up? Fun camper, work trailer?

That is great to hear, even with some modifications I am glad this is what you were wanting. That truck bed camper set up looks awesome. Do you have any big trips planned this year?

Wow, Brian. Thanks so much for your in depth review and experience with installing the air bags. You gave some really solid tips and advice, especially the one about removing the tires. How's the ride now when you're off road?

What all did you end up having to do to the brackets to get them to fit, if you don't mind sharing?

Wow that's great, Slater :) Did you get the travel trailer a year ago too, or have you had it for a while? Any recommended destinations for your viewers at home?

Product works great and helps level the truck during towing. I have noticed a difference in the amount of travel my back wheels have when offloading. But I knew that would be a sacrifice.
