Features to know about
Stay Level and Confident Under Heavy Loads: 5,000-lb Load-Leveling Support
When you’re hauling a heavy trailer or a bed full of gear, rear sag can make steering and braking feel loose. Firestone Ride-Rite air helper springs add up to 5,000 lbs of load-leveling capacity between the frame and rear suspension to keep your vehicle level and stable. With the truck riding flat, your steering stays precise, braking feels balanced, and your headlights stay aimed where they should.
Fine-Tune Your Ride for Every Trip: Adjustable Air Pressure from 5 to 100 psi
Every load is different, so these double convoluted air springs let you dial in the pressure you need—anywhere between 5 psi and 100 psi. Add air when towing or carrying a heavy load to maintain control and balance, then release pressure for an easy, comfortable ride when unloaded. Each bag can be adjusted side-to-side with separate inflation valves to level off uneven loads.
Durability That Holds Up for the Long Haul: Reinforced Rubber and Crimp-Rolled Seals
Firestone’s double-convoluted design uses four layers of reinforced rubber wrapped with a braided wire girdle for exceptional strength and burst resistance. The rubber bellows are anchored by corrosion-resistant metal end plates and crimp-rolled seals that keep them locked tight. This heavy-duty build prevents permanent sagging, absorbs road shock, and softens contact between axle and frame to keep your suspension working like it should.
Smooth Installation with Everything You Need Included
Each Ride-Rite kit comes complete with custom brackets, hardware, air line tubing, and manual inflation valves—no scramble for extra parts. The brackets mount securely between the axle and frame, and routing the airlines to the bumper keeps valve access simple. Once installed, you can pair the system with optional Firestone or Air Lift compressor kits for easy air control from inside the cab whenever you need it.

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.

The bags seem to work well but the installation instructions were confusing, this was the case even after I have previously installed an earlier version in another truck. The install confusion was related to if the lower bracket needs to be installed when you have a jounce bracket. Every image on the instructions show the bracket in place yet it’s not to be used if you have a jounce support.

The video is very helpful. The airbags work as they should. The installation needed some modifications which a lot of people would not be able to do? Grinding away to go around a brake line.

Took a few hours to install on my 2024 f350 but very happy with the results. After installing them and putting 5 psi in them they were 7.5” between the top and bottom plate. Instructions called for 6.5” which it was before I added air so I called tech support to confirm that was okay and they said it was. True test will be next week when I get my 5th wheel and set down in the bed.

I installed these air bags on a 2024 F250 and it took about 8 to 10 hours to complete the installation. Most of the time went into installing the driver side. After an hour or so of struggling to get the lower drivers side bracket to sit on the jounce striker plate, I determined that there was no way to do so without cutting off a portion of the lower bracket to clear the brake line mounts. I emailed with firestone and they confirmed it was okay to cut / remove a portion of the lower air bag bracket to clear the mount for the brake lines. Bottom line is this kit does not fit a 2024 F250 without some serious modification. This could have been easily avoided with some better engineering on Firestones part and next time I will be looking at a different brand. The only reason I gave these 3 stars, is that they are working great after a 300 mile trip with my truck camper.

Bought these for when we tow our 5th wheel. pretty easy install but where they have you cut part of the bracket or cut your brake line holder was a little strange. Bracket that is on the edge of the Joust doesn't even touch the axle tube so not even sure why it was needed. Put it on the passenger side but was not going to cut my brackets on the driver side so it did not go into the truck. Will keep an eye on it just in case it does bend but I would be surprised if it does. Take your time on putting the tubes in and you shouldn't have any leaks. Had this set on my other truck and loved them. Great company with a great product.

I installed these springs myself. I recall having a question during the installation and it was quickly answered by a customer rep. The springs have worked well whether my truck is empty (7 psi), hauling my motorcycle (20 psi) or towing my fifth wheel RV (50 psi). Overall I’ve been pleased with the product

Easy install except for installing the air valve in my bumper (limited space for my hands). Also, recommend using a block of wood to hold the air bag compressed when you are tightening the air bag (on top). Also, very easy to mark index marks when the brackets are not yet installed

Product seams good, pretty easy to install. Two problems:1. Etrailer sent me some that were obviously used. Had paint scuffed off on stress points. I would return them, but need them for a camper I’m getting this week. Hopefully they’re not structurally damaged from the previous use. 2. The directions are a little off. I have a 2024 F350 and some of the mounting locations are slightly different than what the directions tell you. For instance, it talks about removing an exhaust hanger, then installing a bracket where it was. There’s no exhaust bracket where they show. Online videos for, the manufacturer made trailer, are also different. Maybe they were installing on a gas instead of diesel.

When the truck is empty it was too rough riding for me! They want you to keep 5 psi in the air bags, this made the back end bounce over bumps! They worked great for hauling my camper!! But I use the truck more for regular driving, so I took them off and found a better alternative!!!

Had a minor hiccup with the spacing between the upper and lower bases but after calling firestone support they reassured me that the angle and spacing was fine and its better to have the bags "stretched" a little than compressed. After the install along with a compressor/tank kit and height control valve i have had no issues with the truck so far

I placed an order for airbag system. The airbag system I received was not the kit that I ordered. Customer service assured me they would ship out the correct kit. I received replacement kit. Kit number was correct, but half the items in the kit were not correct. In the process of returning shipment for refund, I have one weekend before my trip so I ordered the kit from a local distributor. Unfortunately, I am paying more, but if there is an error in the shipment, I can go to a brick and mortar shop locally and get the correct kit. If I was not in a time crunch, I would wait for the cheaper kit from etrailer. I understand Firestone changes their numbers frequently.

This does not fit 2022 F350 properly! I called etrailer first and they referred me to Firestone. I got ahold of a technician there and he confirmed the instructions wouldn’t work with the 2022 F350. He told me to flip the bottom bracket and let it rest on the jounce tongue. I did this and still didn’t like the way it was set up.I pumped 80 psi in it and didn’t like the way it looked.I took it back off and used the bracket that was supposed to rest on the axle and modified it and welded it on the end of bottom bracket to the outside of the jounce tongue to give it more support from twist. Now it looks great when 80 psi in it. Long story short, It wasn’t a quick install.

- Firestone Air Bags for 2026 Ford F-350 FX4 DuallyHey Doug! The Firestone Ride-Rite Air Helper Springs # F35FV are the right kit for your 2026 Ford F-350 FX4 dually. However, you will need to measure to be sure it fits. The distance from the top of your rear axle to the top of the jounce bump stop must equal 40, 70 or 80mm for this application to fit. The same is true for the Red Label # F95FV with the higher rating. If you're looking for a complete kit with an air compressor you can choose from the following: -Firestone Ride-Rite Air...

If this distance is 40, 70 or 80mm, then the kit will work. If its 50 OR 55mm, Firestone doesn't offer a compatible kit. If the measurement IS 50 or 55 mm, the Air Lift # AL23FJ will work.

Keep in mind though that the onboard scale basically works by measuring how much the truck is squatting, and gives you a weight based on that.

The Firestone Ride-Rite Air Helper Springs # F35FV call for the use of the front holes when you install them. However, you can use the other set of holes if that gives you better alignment.

I recommend rechecking your wiring to make sure it's correct with no loose connections and then check the voltage at the compressor with a multimeter # PT89ZR to see if you're getting 12 volts. If not, then check your fuse and trace the power wire back to...

Hey, Mark. You should've been able to slightly move/bend the brake line. I know some people are not comfortable doing that so you could make modifications to the bracket like you did.
