Features to know about

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

When heavy loads make the rear sag, steering can feel light and braking less certain. The Firestone Ride-Rite Air Helper Springs provide up to 5,000 lbs of load-leveling capacity, keeping your vehicle level and stable under load. Installed between the frame and rear suspension, they help maintain even weight distribution and level headlight beams for better control when hauling or towing.

Fine-Tune for Every Load: Adjustable Air Pressure from 5 psi to 100 psi

Every haul is different, and these air springs let you dial in the right support for each one. You can manually adjust pressure between 5 psi and 100 psi to match your load size or driving conditions. Add more air to reduce squat and keep your vehicle level with a heavy trailer, or drop pressure to the minimum for a smoother ride when unloaded. Each side can be inflated individually, helping you level off-center loads with precision.

Smooth Out the Road: Double-Convoluted Design for Ride Comfort

Bumpy roads and uneven loads can make a truck feel harsh. The Ride-Rite system uses double-convoluted rubber air springs with four layers of reinforced rubber and a braided wire girdle for strength and cushioning. This setup absorbs road shock and softens contact between the axle and frame, preventing bottoming out while keeping the ride comfortable and controlled even on rough pavement.

Built Tough for Long-Term Use: Reinforced Rubber and Corrosion-Resistant Hardware

Durability matters when you rely on your suspension every day. Firestone’s rolled crimp seal secures each air spring to corrosion-resistant metal end plates for lasting, leak-free performance. The heavy-duty rubber construction withstands high pressures up to 100 psi while maintaining flexibility through years of use. All brackets, hardware, airline tubing, and separate valves for manual inflation are included for a complete setup that’s ready to handle real work.

5,000-lb Capacity. Ride-Rite air springs enhance your factory suspension for safety and stability when you are hauling heavy loads. They reduce strain on your rear axle, keep your vehicle level, and adjust to load size for a consistently smooth ride.

by:

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!



by:

Just what my Tundra needed to help balance load of bed and trailer.
etrailer.com and the products they offer are 100% in my opinion.
Thank You for your excellent service and follow up.



by:

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



by:

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!

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.

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



by:

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.

Very easy instructions and easy to install. Going to get another for my wife's jeep. I love it.



by:

Install wasn’t the easiest but it has worked flawlessly since installation. I’m constantly loading in and out my camping setup so the adjustability is awesome. Easy to adjust I just use a bike pump.



by:

This company was great to work with. Didnt have the product in stock that i ordered. They contacted me and told me that there. Would be a delay on my order. Which was fine. Ive had the ride right air bags. On my truck now for 8 daya love them. Made my truck rides much better. The install was very simple. And easy.



by:

I run ride rite air bags on every truck I own I have tried other brands but they just don’t compare, the first set I tried 11 years ago still on that old truck and haven’t failed yet if I blow one tomorrow it wouldn’t owe me a dime it’s done it’s job so yes they are durable and super easy to install , Chevy 2500 and Toyota Tacoma



by:

These are very well built, and the installation instructions were clear and easy to follow. I run my Tacoma with a camper shell, and the weight always had the back end squatted a little. These air springs require 5 psi minimum, and I've got 7 in there now, and the level is great. I test drove at 80 psi just for fun, and the truck looked and felt silly. But the real reason I got these is so I can handle loads in the bed and/or tongue weight from trailers. The diameter of the upper and lower disks on the springs is about 4.5 inches. Doing the quick math, the pair of springs will compensate for about 320 lb of load (over the axles) for every 10 psi you inflate. Tongue weights are applied farther back on the vehicle so it works out to about 225 lb of tongue weight per 10 psi given the geometry of my Tacoma. At any rate, these springs will compensate for any conceivable load I'd put on this truck. I'm very happy with them.

Oh, I drilled and installed the inflation valves in the bumper, right under the license plate lights where they're unlikely to get stepped on or have loads dropped on them.

You're much better at math than me, Clark! I really do appreciate all your attention to detail with this kit as well as with your truck. How often do you are you carrying a load in the truck?

Hi @GwendolynY, It's pretty random. This is my daily driver (when I'm not commuting on my bike) and also my utility truck for hauling stuff. The reason I got the air springs is to prepare for a 2500 mile trip from Texas to Colorado and back towing a car hauler with my son's Miata on it. The gross weight and tongue weight are going to be close to my little truck's limits, so I want to beef things up and be ready for the load. Holler with any questions. Clark PS I have a couple more photos of the installation, but when I wrote my review I seemed to be limited to two photos; let me know if there's a way to add photos.


by:

Brackets bent in first few months apparently due to not enough air pressure. Warranty department was cooperative with replacement.
Seems to me a better mounting design could be used. Instructions need some work also but product performance is what to be expected.

Brackets kept bending. Eventually distorted the frame. I removed them and went with another product.



by:

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!
