Features to know about

Stay Level and Confident Under Heavy Loads: 7,500-lb Load-Leveling Capacity

When you’re hauling your heaviest gear, keeping the truck level makes all the difference in control and safety. The Firestone Ride-Rite Red Label Extreme Duty Air Helper Springs add up to 7,500 lbs of load-leveling capacity to support your rear suspension. They help prevent rear-end sag, keep steering and braking steady, and maintain proper headlight aim even when towing or carrying serious weight.

Fine-Tune Your Ride: Adjustable Air Pressure from 5 psi to 150 psi

Every load drives differently, and these springs let you dial in your setup. You can manually adjust air pressure between 5 psi and 150 psi using separate inflation valves for each side. Add more air for towing or heavy payloads, or drop pressure for everyday driving comfort. The dual inflation setup helps balance off-center loads and smooth out rough roads so the truck feels stable and predictable no matter what’s in the back.

Built to Handle Real-World Strain: Reinforced Red Label Construction

Firestone’s Red Label air springs are built for extreme duty with four layers of reinforced rubber and a braided wire girdle that forms a durable double-convoluted design. The top and bottom plates use corrosion-resistant metal and a rolled crimp seal that keeps everything anchored tight, even when fully extended. These details boost burst pressure strength and long-term reliability, so you can count on them mile after mile.

Straightforward DIY Install: Complete Hardware Kit Included

The kit comes ready with vehicle-specific brackets, air springs, hardware, air line, and separate valves for manual inflation. The brackets bolt directly to the frame and axle for a no-drill install that fits cleanly in place. Route the air lines to your bumper for easy access to inflation points. Once mounted, the system works seamlessly with optional accessories like compressors or gauges if you want on-the-fly pressure control later on.

Despite ordering for my specific year, make, model of RV I had to modify both the air spring brackets and the sub-frame of my RV in order to get these to fit. Turned a 2-hour install into a 6-hour nightmare.
by:
When air bags were inflated the supplied brackets bent. We built heavier brackets and reinstalled. After inflation air bags functioned as intended.

Oh no! I asked the manufacturer if this is a common problem. They have responded that the brackets would not bend by putting air in the air spring. It would take more force to ben those brackets. Low air pressure under load can bend brackets over time because the air spring will continually pound on the bracket. There is not enough force to bend the air spring by inflating to 150 psi. How soon after you inflated the bags did the bracket bend?

Delivery was very fast...thank you!!
On a 2022 Nexus Rebel 30 R, not as simple as told..I had to modify parts of tubing frame of floor support and reinforced everything...took me 10 hours, thanks to the hydraulic jacks. Very happy with the ride now ! It is more firm and and almost removed all the sway on the rear. So far we love it !!
by:
Excellent product. Significantly improved the ride on our motorhome with the International CV (GM 6500) chassis.

Installation was straightforward. I used the pdf instructions included on the product page (QR code included in the box didn’t work) and a few of the videos posted on the product page for my truck model to cross check my work. Someone else mentioned it took about 4 hours, which was spot on. I ordered a few of the tools I didn’t have on hand and was able to raise the bed a few inches with a floor jack at the receiver to create some more space. With removal of the spare tire I had a reasonable amount of room to sit and work. I’ll update my review after I’ve had a few opportunities to load my truck camper.

Glad to hear the install went smooth for you Brian. Four hours isn't bad doing this solo! Also glad you got some new tools out of the deal. Let us know how these perform and if you need anything else.

by:
Install was straightforward. Instructions are pretty good and easy to follow. I paired with an onboard air compressor with wireless control which makes adjusting air pressure in the bars super convenient.

A year in and still 5 stars. The ride and controll is noticable better with the air bags inflated to just 60psi when towing my 16K lb 5th wheel. I run with about 30 psi if Im hauling a lighter load and just keep 5psi in them when Im empty. I have had no issues at all with the air bags or my on board compressor. Absolutely recommend this set up.

by:
This set was a replacement for the ones on my F350 that were already on the truck. Everything went back together with ease once the old bracket were removed. With one air compressor air is is delivered to the air-ride system one the truck is started. I pill a fifth-wheel with a tongue weight of around 3600 pounds. With this system I'm able to level out the truck.

The ride-rite air bags are working great. I run 15lbs pressure in them all the time due to my fifth wheel attachment in the bed. I run 60 to 70 psi pulling my fifth wheel with a tongue weight of 3650 which is not a problem for the air bags.

No issues after a year of using these airbags while towing my 16K 5th wheel.

It's been my experience that Etrailer sells quality products at a good price with free shipping. The recent Firestone heavy duty 7500 lb airbags are no exception. I had originally installed the lighter duty 5000 lb bags and they lasted 10 years. The airbag hardware is the same as my originals so all I had to do was pop off the bags and air lines. That's good because the existing countersink bolts connecting the hardware to the chassis are never coming off. The installation took 1 hr and 15 min. I thought I had a problem after checking the system for leaks, There wasn't any leakage but the pressure had gone down from 70 to 63 psi. I contacted Etrailer and they offered to replace the bags. However, I came to realize that my pressure gauge was slowly dying and giving me faulty readings. I also realized I put in 120 degree air from my compressor on a 90 degree day and then checked the bags the next morning at 60 degrees. The pressure does drop somewhat due to the temperature differential. The removal of the old bags took longer than the installation of the new bags. I began by removing the old hardware and realized the csk bolts were not coming off, which is why I just used the existing hardware. I had to cut the bags and visegrip them up to the hardware to keep them from spinning when removing the nut holding the bags onto the hardware. A word of caution...don't be afraid to zip tie the air lines every 10" or so. My original air line had some slack and got caught between the chassis and the bed so got a bit flattened. I'm pleased!

Product still functioning perfectly one year later!

by:
This seems like a high quality kit. Two of the four long bolts that come in from the brake caliper side and clamp the lower bracket to the spring perch were time consuming to route,(maybe because my 2026 F450 has an electronic emergency brake), but are doable with perseverance. Other than those two of four bolts on each side, very easy to install. I watched the video where the tech was installing on an F350 with no jounce base coming from the leaf spring and also no electronic emergency brake, not really applicable to a newer F450 with the jounce perch and an electronic emergency brake. I would suggest that etrailer produce a video for installation on a newer F450 with the jounce perch and an electronic emergency brake.
by:
I was concerned about the tongue weight of the 42 ft Solitude. Had a local mechanic install the air-helpers on the GMC 1 Ton (long wheel base) which did not take him long at all. Have recently towed the camper over 1100 miles and am very satisfied. Running the PSI @ 60 while towing and 10PSI while unhitched.
by:
2023 GMC Sierra 3500
Install went well, instructions were easy to understand. The only thing I didn't like was the big nut (holds top of airbag to bracket) interfered with bracket securing the top bracket to the bounce/jounce part. Not sure what the fix would be, I used a wrench to get it on (it should have threaded on by hand most of the way).

I don't have any leaks, all seems good. We tow next week and that will be the test. I expect no issues, it all looks good.

still working great

by:
Quality product and relatively easy installation with basic mechanical skills. Instructions are adequate. I haven't traveled with my 3800 pound slide in camper yet but I expect these will greatly improve my ride.
by:
Little different compared to Firestone I installed 9 years ago. The top mount is a big improvement.
The bottom mount looked awesome using clips under the pad instead of the vertical and horizontal U Bolts on the older version I installed in 2017.
The park brake cable bracket was directly in the way of the pinch bolt for base plate clip connection
pass side.
I made it work with a little fanning on the lower clip.

It was about 98 degrees and have not swapped the drivers side out yet being it is still functional. All good with me, if you had not asked for a review etrailer would not have heard from me.
by:
These were a great purchase. I did have a local shop install them rather than doing them myself (I didnt feel like rolling around in the gravel for 2 hours). I have an F450 and tow a Brinkley G3950. I towed the trailer some without the airbags and the truck did fine. With the bags installed and inflated to about 40 psi, my truck handles perfectly.
by:
2025 Chevrolet Silverado 2500
I usually don't leave reviews unless i'm being compensated. When searching for airbags online, I found many conflicting reviews, so I am compelled leave a review. My truck is a 2025 2500 Silverado LTZ. The install was "simple", but nothing is "easy" it took some effort. 4 hours start to finish including setup and clean up moving at a leisurely pace. All parts were included,instructions were clear. After install, I checked for leaks and nothing leaked. At 5lbs,unloaded truck, the airbags are imperceptible, feels like riding on stock suspension. This was the most important result I was hoping for since the truck is a daily driver. At higher pressure, hauling a load, they do the intended job quite well. Very pleased, highly recommend.

@GwendolynY I'm hauling a 5th wheel on a B&W companion with the B&W Turnover ball gooseneck. The pin weight is 2500lbs. The ride is noticeably smoother with the bags at 40psi at highway speed. Couldn't be happier with the performance of the setup.

  • Do I Need To Worry About Over Extending Firestone Air Bags When Leveling My RV?
    Hello Clayton. With a firestone air bag kit, you really do not need to worry about over extending them. The top and bottom plates use a rolled crimp seal that is quite strong. They can handle being extended so you do not have to worry about damaging them when leveling your RV. Some other brands of air bag cannot handle being extended, but the design of the Firestone allows them to extend without risking damage.

  • Air Bags for 2023 Chevrolet Silverado 4500HD Flat Bed
    Hello Cesar; the Firestone Ride-Rite Red Label Extreme Duty Air Helper Springs # F56ZR you were looking at will fit your 2023 Chevy Silverado 4500. These have a bolt-on installation and will not require modification to fit. If you want to add an air compressor to adjust the pressure from the cab you will need one capable of 150 psi like the Firestone # F2097 (single path) or # F2168 (dual path with air tank).
