Features to know about

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

When heavy trailers or bed loads make the rear end sag, these Firestone Ride-Rite air springs add up to 5,000 lbs of load-leveling capacity to get your stance back where it should be. Installed between the frame and rear suspension, they help keep your vehicle level, maintain even load distribution, and improve steering control and braking when hauling or towing. With the truck sitting level, your headlights stay properly aimed and your tires wear evenly no matter how much weight you’re carrying.

Dial In Your Ride: Adjustable Air Pressure from 5 psi to 100 psi

Every load is different, and Ride-Rite springs let you fine-tune your setup. With adjustable air pressure from 5 psi to 100 psi, you can soften the ride when empty or firm things up when maxed out. Each side adjusts manually through individual inflation valves, so you can balance off-center loads for better handling. Once set, the system smooths out bumps and keeps your suspension from bottoming out when the job gets heavy.

Built Tough for Real Work: Double-Convoluted Rubber Construction

Firestone’s double-convoluted design uses four layers of reinforced rubber with a braided wire girdle to boost strength and burst pressure. Corrosion-resistant metal end plates are sealed with a rolled crimp to keep the bags securely anchored and leak-free. The result is dependable load support that holds up to years of towing, hauling, and road shock without sagging or wearing out your leaf springs.

Straightforward Installation: Custom Brackets and All Materials Included

Each kit comes complete with custom-fit brackets, air line tubing, hardware, and air valves for manual inflation. The brackets mount between your suspension and frame to provide solid attachment points for the air springs. Drilling may be required on some setups, but once installed, you’ve got a reliable suspension upgrade ready for serious hauling duty. Optional switches, gauges, compressors, and air tanks (sold separately) make adding in-cab control even easier down the road.

Worked great, big improvement. Mounted on a 2004 Excursion diesel with 6 inch lift. I tow a 12k pound camper and the air bags help with more stability, less sag and bouncing while driving. Huge improvement and brings me close to the empty height of the vehicle. Also easy to install with the spacers required for my lifted truck.
by:
I have not installed it yet but the customer service when ordering was amazing. I was walked through returning parts I did not need and getting the correct complete kit for my needs.
by:
Quality parts, fast shipping. Very happy with the product , hauled my 30 ft camper from Missouri to Corpus Christi TX and back, smooth ride .
by:
Went together quickly and worked as described. I like the individual adjustment ability for each side in order to balance onboard load. I would recommend these to anyone that had a need for the boost when towing.

Great to deal with fast shipping

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:
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!

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:
A great product, works well. Had to remount an electrical plug with zip ties
by:
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.

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:
I have put these on on every work truck I’ve had. They are great to keep heavy loads from keeping your truck from sagging after awhile. The guys had what I needed and got them to me in good time. Thank you.

Just what my Tundra needed to help balance load of bed and trailer.

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!
by:
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:

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:
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.

  • Recommended Air Bag Kit for a 2000 Ford Excursion
    Hey Loren. The correct Firestone Ride-Rite for your 2WD 2000 Ford Excursion is item # F2255. The Firestone Ride-Rite item # F2251, you referenced only fits the 4WD models. The Firestone Ride-Rite item # F2255 has a 5,000 lbs capacity that will level out the rear end of your Excursion when you are towing a trailer or hauling a bunch of gear in the back. All mounting brackets are custom fit and the kit includes all the hardware you will need for installation. I have linked an installation...

  • 2003 Ford Excursion Air Bag Kit Recommendation
    The air bag kit I recommend going with for your 2003 Ford Excursion is the Firestone Ride-Rite Air Helper Springs # F2251 which don't have the inner bump stops, but that's because they don't need them. Firestone has been in the air bag business a long time and has the best construction due to 4 layers of reinforced rubber, the braided wire girdle to give it the correct shape, and the rolled crimp seal that keeps the mounting plates from damaging the air bags.

  • 2005 Ford Excursion Squats when Using Husky Weight Distribution with 9,000 Pound Trailer
    Let's first look at the numbers. A trailer weighing 9,000 pounds will have a tongue weight in the neighborhood of 900 to 1,350 pounds. But when you calculate tongue weight for weight distribution you also have to factory in the weight of any cargo loaded behind the rear axle of your 2005 Ford Excursion. So for example if your trailer's tongue weight is 1,100 pounds and you have 200 pounds of cargo behind the rear axle of the Excursion the total tongue weight would be 1,300 pounds and you...

  • Recommended Air Bag Suspension Kits for 2001 Ford Excursion
    The rear axle air bag suspension kit I suggest for your 2001 Ford Excursion 4WD is Firestone kit # F2251. This air bag system will give you up to 5000-lbs of adjustable load support. You can add a compressor kit like the Air Command I # F2158, which controls both bags at the same time, or dual-path Air Command II compressor # F2178 which allows for independent control of each bag's pressure. Since these bags can operate with as little as 5-psi pressure (but never less than that) you can...

  • Can Firestone Air Bags be Installed on a 2001 Ford Excursion that Does Not have Jounce Bumpers
    To install Firestone Ride-Rite air bags # F2251 on a 2001 Ford Excursion 4x4 the jounce bumpers would have to be removed and are not reinstalled. So not having the jounce bumpers actually saves you a step for the installation. I also recommend using a compressor kit, # F2158, so you can add or remove air from the air bags from inside the vehicle. The kit is not required but makes load leveling a lot easier. If the 5 inch block you mentioned means that the frame is 5 inches further away...

  • Recommended Air Bags and Compressor for Tires On 2002 Ford Excursion
    The Firestone Ride-Rite Air Helper Springs part # F2255 for 2WD or part # F2251 4WD are what I recommend for a 2002 Ford Excursion. These air bags offer a bolt-on fit and will do a great job of providing extra support when towing or hauling. In order to inflate the air bags from inside the vehicle, you'll need an air compressor system. The Air Command II Xtreme Duty Compressor part # F2549 is what I recommend for this as it has everything you need for a complete installation, including...

  • Charging Trailer Battery and Weight Distribution for 38 ft Primetime Lacrosse 3311RK
    Most people will trickle charge their trailer battery through the 12-volt accessory circuit of the 7-way trailer wiring connector. You'd basically just run a wire from the 1:00 pin of the 7-way to the positive terminal of the battery # BRW37FR and it would receive a trickle charge when you are towing. You'd want to use 10 gauge wire like the # 10-1-1 which we offer by the foot. If the tow vehicle side of this connection isn't made you'd can use 10 gauge wire for this as well but you'd also...

  • 3 inch Spacer Kit Recommendation for Firestone Ride Rite Kit part # F2251
    Firestone does make a 3 inch lift spacer part # F2368 that you can use with the Firestone Ride Rite kit part # F2251 that you referenced. If the lift you have on your vehicle adds 3 inches to the distance between the axle of your vehicle and the frame this is the correct kit to use.

First, style # F2371 fits on Ride-Rite models that mount to the vehicle axle. The other one, # F2370, fits on models that mount to the leaf spring stack. The kit that you have, # F2251, is an axle mounted kit so you would need spacers # F2371. The spacer kit used needs to be same as the amount of lift on the vehicle.

  • Air Bag Kit Recommendation for 2000 Ford Excursion Towing Travel Trailer
    Hey Wesley, the Firestone kit part # F2251 is going to be your best option for your 2000 Ford Excursion. These have a 5,000 lb weight capacity but that is just the additional lifting capacity they can provide and is not the assumed capacity of your Excursion. How does the Excursion handle your travel trailer as-is? That thing is a beast of an SUV for sure haha. Are you wanting a compressor kit as well?

  • Weight Distribution for 2001 Ford Excursion Pulling a 7500lb Holiday Rambler Trailer
    An air bag or helper spring set-up is more effective for dealing with weight carried in or on the vehicle itself. A properly sized and adjusted weight distribution system will preform several tasks. It will eliminate the sag experienced when a trailer is hitched up, it can reduce or eliminate trailer sway and it can also improve braking performance and and steering response. A weight distribution system accomplishes this by using leverage to transfer a portion of the trailer tongue weight...

  • Suspension Enhancement Recommendation for a 2000 Ford Excursion with 6 inch Body Lift
    A block lift is a body lift so you would not need the spacers. The only time you need to use lift spacers with suspension enhancement is when you have a suspension lift. So the Firestone Ride Rite part # F2251 would fit your 4x4 2000 Ford Excursion without needing them.
