Features to know about

Stay Level and Confident Under Load: 5,000-lb Ride-Rite Air Spring Support

Heavy loads can make the rear end of your truck sag, throwing off steering and braking. The Firestone Ride-Rite Air Helper Springs add up to 5,000 lbs of load-leveling capacity to keep things even. Installed between the frame and rear suspension, they help maintain proper ride height, reduce strain on the axle, and keep your headlights aimed where they should be. With balanced support from front to back, you get smoother handling and better control when towing or hauling serious weight.

Dial In the Ride for Any Load: Adjustable Air Pressure from 5 psi to 100 psi

Every job is different, and so is every load. You can fine-tune these double-convoluted air springs anywhere from 5 psi to 100 psi to match what you’re carrying. Add air for towing or heavy cargo to firm things up and level the truck; drop it back down when empty for a softer, more comfortable ride. Separate manual inflation valves let you adjust air pressure side to side to even out off-center loads and keep your setup stable on uneven terrain.

Firestone Ride-Rite air line tubing installed at rear bumper for manual inflation valve access on vehicle

Smooth Out the Rough Stuff: Double-Convoluted Rubber Springs

Rough roads and heavy trailers can beat up your suspension. These Firestone Ride-Rite springs use four layers of reinforced rubber with a braided wire girdle for strength and shock absorption. The double-convoluted design gives maximum load support while softening contact between axle and frame to prevent bottoming out. The rolled crimp seal keeps everything secure for long-term reliability mile after mile.

Built Tough with Everything You Need: Complete Installation Hardware

Each kit comes ready for the install with custom brackets, hardware, air line, and separate valves for manual inflation. The corrosion-resistant metal end plates mount securely between your frame and suspension, providing solid anchor points that hold up under pressure. Optional switches, gauges, compressors, and air tanks are available separately if you want quick in-cab adjustments later on.

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:

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.

Great product gonna keep my truck nice and level for towing arrived on time thanks.

Fast delivery and installation was about an hour. Not bad at all

Seems to fit very well, almost to close tolerance on the ability for the fit. You have to get it right before it will go together. better in the long run. Will wait to see how well it holds air and how long the air bags will last



by:

Great product! Only thing that would put it over the top is a PSI gauge so I can monitor the pressure in each bag. Other than that, great quality product.

TanceThe air ride has made towing my 30ft trailer so much easier. It's a great pruduct. Plus the folks at etrailer are super and constantly ask if you need assistance

Airbags worked perfect and were easy to install. The customer service was excellent and the items arrived very quickly.

Shipping was fast and the product fitted perfect on my 2004 Titian. It would be nice if an installation video was available for the Ttitans



by:

Being a Truck Driver in all 48 states I know from experience these air bags will solve the problem of my pickup dropping so low when I hook my 27 footer dual axle RV. This product is made with quality and can support my needs in having fun with our RV.



by:

The installation was relatively easy. The airbags work great. When pulling a trailer it makes the ride much smoother and my vehicle stays level



by:

The Ride-Rite air helper springs work great. If I'm pulling a heavy trailer or loading my truck with a heavy load, I can add air to adjust the ride and level my truck. They really help the ride.

The Firestone air helper springs are still working great one year later. If I load my truck with a heavy load like pavers or bulk sand 1200lb bags,I just add air until my truck is level. I have loaded the truck while using a weight distribution hitch to pull a sixteen foot box trailer. Its a wonderful product. I highly recommend.

See what our Experts say about this Firestone Vehicle Suspension

  • Is There a Way to Determine Added Tongue Weight with Truck Bed Camper When Using Weight Distribution
    That's a really hard number to get an exact figure on but the best way to estimate would be to take the entire weight of the camper and divide it by about how much of the camper sits behind the rear axle. Often times this can be between 25 and 50 percent depending on bed length and camper length. Like it sounds like you are aware of, any additional weight added to truck bed behind the rear axle would count as tongue weight when picking out a weight distribution system.

  • Does Firestone Hardware Kit FA21-760-2525 Fit Firestone F2355

  • How to Find an Air Leak on a Firestone Ride-Rite Air Helper Spring System
    The maximum air pressure that the Firestone Ride-Rite Air Helper Springs part # F2355 can be filled to is 100 psi. In addition to max pressure there will need to be a minimum of 5 psi in the airbags at all times in order to avoid deformity. The airbags should stay inflated to the psi at which they are set to. If they lose air over time like you mentioned then you have an air leak somewhere in the system. The best way to find an air leak would involve mixing up a bottle of soap/water and...

  • Can Firestone Air Bags be Used with Weight Distribution Hitch when Towing a Trailer
    You could use air bags and weight distribution at the same time. But if you are experiencing rear end sag on the tow vehicle caused by towing a trailer then the best solution is weight distribution. But not just any weight distribution system. It has to be the proper capacity. To choose a weight distribution system you will need to go by the total tongue weight of the set up. This is calculated by taking the tongue weight of the trailer, when loaded and ready to tow, and adding to that...

    The RoadActive Suspension Kit # RAS4611 will not work with either the Firestone Ride-Rite Air Helper Springs # F2355 or Air Lift Ride Control # AL59554 on your 2014 Nissan Titan. All the kits involve a mount placed at the U-bolts of the leaf springs to attach the necessary hardware on your Titan.

    The correct spacer to use with the Firestone Ride-Rite Air Helper Springs part # F2355 on your 2007 Nissan Titan will be the one that matches the actual lift that the kit you installed provided. If you have an actual 6" lift in the rear then the correct spacer for you is the Lift Spacer for Firestone Ride-Rite Air Helper Springs part # F2374. However, lift kit manufacturers often overstate the actual lift so more than likely you will be looking at either part # F2370 or part # F2373. I...

  • Suspension Enhancement Recommendation for 2006 Nissan Titan That Will fit with 5th Wheel Rails
    It looks like the Firestone kit part # F2355 could fit on your vehicle with fifth wheel rails # C16470-204, but since it hasn't been tested we really can't say for certain. The safe bet would be the Timbrens that we know will fit. Such as the Timbren kit # TTORTUN4 for 2-wheel-drive Titans (or part # TNRTTN for 4-wheel drive models). Since these springs install in place of the OEM axle bump stops there is no conflict with 5th wheel mounting hardware. Also, since these springs do not...

  • Can Truck Air Bag System Be Utilized to Distribute Weight of 5th Wheel Camper?
    For a 5th wheel camper the Firestone Ride-Rite Air Helper Springs - Double Convoluted - Rear Axle # F2355 (fitting a 2004 - 2015 Nissan Titan) will not help distribute as much as it will help with load leveling. Air spring systems are adjustable side to side if you set them up for that function and will help with shock absorption and leveling the rear sag of your truck. They are great for adjustability to give you the best possible ride with your trailer. You may want to consider using...

  • Do You Hook Up Weight Distribution First or Inflate Air Bags First on a Toyota Tundra
    What you will need to do is couple the trailer to your Tundra and then use the air bags to level the vehicle as needed. Then you would engage the spring bars on the weight distribution system. You then may or may not have to adjust the air pressure in the air bags.

  • Front and Rear Suspension Kits for 2008 Nissan Titan 4 x 4 with WD Hitch and Iron Bull Front Bumper
    You have an interesting combination of circumstances with your 2008 Nissan Titan 4x4 that is both towing a 7000-lb trailer with a weight distribution hitch (WDH) and also using a fairly heavy Iron Bull front bumper with winch/hitch to maneuver the trailer. In general, you can say that a WDH and a front-axle suspension helper system will tend to work against each other. The WDH will try to push some of the trailer's tongue weight (TW) forward onto the front axle while the front axle suspension...

  • Recommended Air Suspension System For 2012 Nissan Titan
    This has been an issue for many vehicles. Using an air suspension system on your 2012 Nissan Titan when the weight distribution system is being used is not a great idea, as they tend to cancel each other out which does no good for you. Many times the problem you are having with the excessive sag is due to the weight distribution system not being set up correctly or may even be the incorrect size.

  • How Difficult is it to Install Firestone Ride Rite Air Helper Springs on a 2005 Nissan Titan
    Drilling is not required to install Firestone Ride-Ride spring, # F2355, on your 2005 Nissan Titan. Really the most difficult part is routing and cutting the lines. You have to make sure the lines will not be pinched or burned by hot components like the exhaust. To cut the lines properly. I recommend using a tubing cutter, # F9009, because you want the cleanest and straightest cut you can get. Otherwise, installation is straight forward.

    The Firestone Ride-Rite Air Helper Springs, part # F2355 will work great on your 2004 Titan. Ride-Rite springs will not increase your Nissan Titan's weight-carrying capacity. Since you have a 1-1/2 inch spacer on your truck the spacers you need for the Ride-Rite kit are part # F2536. These spacers attach between the bottom of the lower bracket and the bottom of the spring on vehicles with a 1-1/2 inch lift.

  • How To Uncouple A Trailer With Spring Bars and Air Bags On Truck
    To uncouple your trailer with weight distribution, you don't really need to do anything with the air bags. The best way to take the spring bars off is to use the jack to raise the trailer and the back axle of the truck a little to reduce tension. Then remove the spring bars. You can lower the trailer with the jack and reduce the air bags to become level (if you need to). Then you can uncouple the trailer.
