Smooths Out Rough Roads: Absorbs road shock and prevents bottoming out for a more comfortable ride.

Durable Double-Convoluted Design: Four-layer reinforced rubber springs stand up to years of heavy use.

Features to know about

Stay Level and Confident: 5,000-lb Load-Leveling Support

Big loads can make the rear sag and the front rise, throwing off steering, braking, and headlight aim. Firestone Ride-Rite air springs add up to 5,000 lbs of load-leveling capacity between the frame and rear suspension to keep your truck sitting level and steady. They take strain off the rear axle, maintain even load distribution, and help keep control when towing or hauling heavy gear.

Smooth Out the Ride: Adjustable Air Pressure from 5 to 100 psi

Different loads need different support. With adjustable air pressure from 5 psi to 100 psi, you can fine-tune the firmness for your setup. Add air when hauling a trailer or heavy bed cargo to reduce sag and bottoming out, or drop pressure when running empty for a smoother ride. Each spring has its own manual inflation valve so you can balance side-to-side loads and keep handling even no matter how gear is packed.

Built Tough for Real Work: Double-Convoluted, Reinforced Construction

The double-convoluted design gives these air springs serious durability and support. Each spring has four layers of reinforced rubber wrapped with a braided wire girdle to increase burst strength. Corrosion-resistant metal end plates are secured with a rolled crimp seal that locks everything together tight. The result is a heavy-duty system that soaks up road shock and cushions contact between the axle and frame to prevent bottoming out under load.

DIY Friendly Setup: Custom Brackets and Complete Hardware

This kit includes custom-fit brackets for mounting the springs between the frame and axle—no drilling required. All brackets, air springs, hardware, airline tubing, and separate valves for manual inflation come in the box, so everything needed for installation is right there. Once installed, you can route the inflation valves to an easy-access spot on the bumper for simple adjustments before heading out with your next load.

All instructions were spot on for my vehicle. Install went smoothly with no issues whatsoever.

However, the package did arrive missing the 12-locking flange nuts - kinda critical. I called Etrailer and spoke with Nick S - he was going to overnight replacements out to me, but since it would have been on Friday before they went out, meant they wouldn't arrive before Monday and I already had my truck tore apart. Nick suggested trying to find them locally if I didn't want to wait, and they would credit me with the amount the nuts costs. I was able to get them off (another site), overnight, so it all worked out. The folks at Etrailer have always been very helpful and accommodating. I can't sing their praises enough!

2015 GMC Sierra 3500

excellent product, very easy (uncomplicated) install. anyone who is somewhat mechanically inclined can install themselves. It took me about 3.5 hours by myself with simple tools and a jack on my garage floor. Hardest part was me getting up and down from the creeper.
On my truck, (2015 GMC) i had to remove Ebrake cable brackets on both sides and reroute, not a big deal. also, did not find it necessary to remove spare tire heat shield, worked around it just fine. Routed my schrader valves through the plate screw holders for easy access.

Still happy with this install, bags help tremendously over bridge joints hauling my 5th wheel. not sure how these compare to Timbren setup, but i would guess better based on being able to adjust pressure. way more stable over bridges and bends in road.

by: Vince 06/15/2026

This installation took twice as long as it should have! The top plate had to be modified to clear the leaf spring U bolts and shock absorber bracket.
The Jounce doesn’t allow the installation of the 3/8@ bolts close the leaf spring that holds the brackets together. I’m not sure what to do with this now. I saw in other reviews where other people had similar issues. Not sure if it’s the universal bracket design vs having slotted holes like your video.
Any help would be appreciated.
Also both valve inserts had to be replaced!

2025 GMC Sierra 2500

This the 3rd truck I've used and installed myself of the Firestone 5,000lb rated airbags on, and not one has ever failed on me. I used them on a 2007.5 Chevy LMM 2500 LT Silverado, a 2020 Chevy 2500 LTZ Silverado, and yesterday I put them on my 2025 GMC 2500 Denali. I did pair my new bags with an Airlift wireless compressor, which is an awesome addition to the bags. I like the fact that etrailer did a comparison video on the Firestone and AirLift bags, and they found the Firestone bags are of better quality and can support the weight of the axle if you lift the truck off the ground by the frame. If you have never installed these bags, you do not have to lift the truck off the ground or remove your rear tires. If you're like me, and do not have access to a lift, I suggest removing your spare tire, which will give you more seating area, and you will not bonk your head into it. Two thumbs up on this kit

After 1 year of use, my Firestone airbags never let me down. Working perfectly. This is the 3rd trucks Ive run Firestone 5000 lbs. rated bags on with no issues.

by: Alec 09/23/2024 One Year Later

I purchased this Firestone Air suspension and installed it myself on my 2017 Toyota Tacoma Access Cab 4x4. Not having a lift, I had to use a creeper and tarps under and beside the truck to do the installation. Installation was pretty straight forward after viewing the video from etrailer a few times and using the provided diagrams. You will need good 3/4" drive hand tools for the installation. An electric or air impact wrench and ratchet also speeds things up. I then installed a mini onboard compressor with remote control for in cab or outside operation. The system has never leaked air but if it did, any time the vehicle is started, the compressor will refill the system. I keep 10 lbs. air pressure in it and raise it to 20 when I haul my dirt bike on my hitch carrier and it compensates nicely and keeps the vehicle level. All good so far.

Still working great as it should and doesnt leak air. The remote controller is really convenient and can be operated from inside or outside the truck. Definitely worth all the work. The shield I fabricated for the compressor keeps road grit etc. Out of the air intake of the compressor which should be a huge help for the life of the system. Love it.

Definitely help level the truck back out with the camper, and bed full of firewood cooler. Installed very easily, but it did have a clearance issue with a bracket almost touching the gas tank skid plate. Some grinding down and krylon flat black paint fixed that issue. But the little tacoma still needs heavier shocks to slow the travel down when hitting bumps. Especially bridge joints back to blacktop. In all worth the money, just need to set aside more money for better rear shocks to accommodate. May eventually change them to the cradles to keep flex availability. As well as less issues when putting the truck on a lift for service.

2023 Chevrolet Silverado 2500

Installation was really easy except for the lower brackets that attach to a lip of metal. There was another piece of metal on the axle that got in the way but i pried and then hammered the bracket into place, squeezing it in. If I didn’t I’d still be able to get the bolt through but I bet as I tightened it down it would move the base plate and wouldn’t be lined up as well. No air is leaking so far. I didn’t buy the compressor so I might screw on some Bluetooth tire pressure monitors so I’ll get notified if pressures drop below 5psi. I have a 2023 Chevy 2500 and surprisingly with 15psi and no load in the bed it rides much better! Doesn’t hop all over the place

I ended up adding an airlift compressor which was super easy to install and everything works great! I got tired of checking pressures, the air compressor monitors psi and kicks on if needed. I would buy and install these things again if I ever end up getting a new truck. Works great when towing my 12,000 pound bumper pull camper

by: Dewey 11/03/2026

2016 dodge Ram Pickup

Works better than expected. Noticed our 40' camper causing the old leaf springs on our 2016 Ram 3500 to sag a bit more than usual. Air bags brought it right back up and got the front alignment right and headlights straight. You'll need an adjustable height hitch as we needed to lower the ball a few notches to get the proper 15% weight on the ball.

2015 toyota Tacoma

I just installed them and put them to work immediately and I am impressed so far! Installation was pretty simple, and they fit great even with an Old Man Emu 3" lift (7 leaf spring stack). It only took about 15 psi to level up the Tacoma even with 1000 Lbs of feed and a steel high rack on it and they handled that load over 50 miles of some very rough west Texas terrain. They seem to be very well made and heavy duty. Time will tell if they hold up but again, I am very impressed thus far!

2020 Chevrolet Silverado 3500

I’d really love to give these a 5 star as they massively improved the ride and porpoising of my truck with a fairly heavy truck back camper. We were shorted one bit of hardware in the kit that caused a 1 hour RT drive to the hardware store for a stupid bolt. One of the hex head flange/wedge bolts for the upper mount was missing . Simple ‘miss’ by someone but was annoying . That aside everything g was great.. instructions were clear and helpful… I’d give them a 2 of 5 for difficulty installing.. any weekend mechanic can do this. The truck rides better and is safer now so thumbs up all around except for Mr Bolt pack loader!

Thanks for being honest with your review, Lee. It really is a bummer when a part, even as small as a nut, is missing causing a delay with the install. However, I'm glad that you were able to get everything installed and that the ride is better and safer now. When's the next camping trip?

by: Mike 10/25/2026

It took a little more time to install than I thought, but then again I’m 72 years old and a perfectionist.
Seriously though, they installed per the instructions and the only modification I had to make was to the passenger side brake line, which had to be removed from its holder and gently bent in order to obtain the recommended clearance.

2019 Chevrolet Silverado 2500

Great product! Quick shipping, good install instructions, easy to use. Installed these on my 2500HD. Next day had 2,500# of shingles loaded in the truck bed. Truck still sat level, and handled great! I highly recommend for anyone moving weight. Difficulty to install from 1-10, 1 being easiest these are about a 3. I would say around the same level as changing a set of brake pads.

by: Mike 04/19/2025 One Year Later

The installation was pretty straightforward, and was managed at campsite with basic tools. It is filled with Milwaukee portable air inflator and has been keeping air pressure set at. We have had good use of it to level truck after loading 5th wheel. I elected to not join both lines together so I can keep individual air pressure in case one had leak but has been fine, I might join them with optional part etrailer offered.
After 1 year and 8,000 miles has been great purchase. All bolt on, no holes to drill, I even placed fill valves in license plate to conceal installation.
Alex at etrailer was excellent as helping us find the correct kit and shipping promptly with great communication and follow up.

by: Al 06/03/2025

Really quite easy installation. Honestly, the hardest part was routing the air line. (that coiled up hose!) I ended up covering the lines with cable wrapping to protect them from any rubbing or scuffing. I also don't have a compatable hitch for the mount, and didn't want to mount them through my bumper in the license plate area because I know I would step on them at some point in time. Product had all the correct parts, high quality, and super happy with it. I wish I had gotten them sooner.

@BrookeM I do, mostly my own, not a professional, but have everything like tire changing and balancing machine, compressor, etc. Didn't need much to do this job which was nice though. just some wrenches, oscilating tool (For the factory bumpers), razor knife, and a drill with an assist from my creeper (To lay on, not my weird neighbor).

installed the Firestone Ride Rite air helper springs with the on board pump and they work great!

by: Steve 04/08/2025 One Year Later

I recommend this to anyone with a 3/4 ton that wants stability without adding springs. It works well at giving support when I hook up to the 5th wheel. Before adding the airbags the rear suspension would settle 4 inch or more when hitching up to the trailer. Now I can control how much it settles and I get more stability and a better ride. Good system and not too difficult to install. I would have given 5 stars but I had to make three attempts to get the airlines to seal. The airlines are plastic and are a tight coil and are tough to straighten and install. I had a leak that I finally was able to remedy after several attempts at connecting. This was frustrating but I am still a big fan of this system and highly recommend these airbags. I have run with as much as 60 psi in the bags and have decided that around 40 is about right for my setup. The truck settles about 1-2 inches with about 40-60 psi.

Glad to hear this, Steve! I am curious, what all did you do to find and fix the leak? I'm always looking for new ways to help folks stop a leak or whatever the issue is :)

by: Fig 07/11/2026 One Year Later

Been a great product for me has worked well for my application I chose to just run individual airlines out by the license plate to air up when needed with a little handheld compressor did not want to spend the extra money on onboard compressor pretty straightforward install
The only thing I changed was the plastic air hoses to braided lines with fittings
You would think braided lines would be standard equipment with these bags plastic hoses are junk
Hope this helps somebody down the road

Air Bag Kit Recommendation for a 2021 Ford Ranger with In-Bed Deck System and Ladder Rack
Hey Joe, sweet ride! For the best and most reliable ride quality I actually recommend picking up the Firestone Ride-Rite Air Helper Springs # F28ZR. The Air Lift Kit # AL88234 with the internal jounce bumpers can produce a rougher ride, and the Ride-Rite air bags have a better construction which is why I recommend the Firestone over the Air Lift. I also recommend checking out the Air Lift WirelessONE Tank Kit # AL67DQ which will keep the air bags within 3 psi of the setting you choose,...

Suspension Enhancement Recommendation for 2019 Ford Ranger
The problem is that your trailer frame is aluminum and basically all trailer manufacturers will not allow use of weight distribution systems with their trailers if the frame is aluminum. So what your best solution would be then is rear suspension enhancement for your 2019 Ford Ranger. For that you'd want the Firestone Ride Rite air bag kit part # F28ZR and you'd be set. This will do a great job getting rid of any suspension sag due to the tongue weight of your trailer.

Are Ride-Rite Air Bags Compatible With 2023 Ford Ranger Tremor
I checked with Firestone, and there is no mention of any issue with the fits on a Tremor package, so your 2023 Ford Ranger can use the Firestone Ride-Rite Air Helper Springs # F28ZR. These will do a superb job of helping with the sag on the back end of your Ranger with your truck camper on so you made a really nice choice. The only other thing I recommend, in order to help inflate and maintain the pressure in the bags, is a compressor, the Air Command Compressor System # F2610.

What is Weight of Curt TruTrack Weight Distribution System
The total weight of the Curt TruTrack part # C17500 is 115 lbs.

I looked up the towing capacity of the 2019 Ford Ranger and it appears to be 350 lbs but you should verify this as well in your owners manual. Also worth mentioning is that it looks...
