Is this right for you? Product Expert Alex H says:

Yes, if you:

  • Have rear sag from towing a 5th wheel or gooseneck trailer
  • Tow different trailers or switch loads often and want to be able to adjust your suspension to match

No, if you:

  • Are trying to fix rear sag caused by your travel trailer - a weight distribution system is more effective
  • Don't want to deal with maintaining air pressure - you need to use an air compressor regularly or install an on-board air compressor
  • Aren't comfortable with complicated installs and don't want to pay someone else to do it for you

Firestone Ride-Rite Air Spring Basics

Firestone Ride-Rite springs are designed to increase safety and reduce the strain on your vehicle when you are hauling heavy loads or towing a heavy trailer. The springs partner with your existing rear suspension system to help keep your vehicle level, maintain even load distribution and increase stability. Hauling heavy loads or towing a heavy trailer can make the rear of your vehicle sag and the front end rise. This puts more strain on your rear axle and reduces contact between your front tires and the road, causing problems with braking, steering control and traction. By adding air springs to your rear suspension, you can help to level your vehicle and improve braking and handling. The air springs also help to level your headlight beams and reduce wear on your tires.

Adjustable Air Pressure

The air pressure in your Ride-Rite springs can be adjusted manually, side to side, to compensate for off-center loads. A centered load improves the stability of your vehicle by reducing body roll. The air springs will also help to absorb road shock and to soften contact between your axle and frame. This prevents bottoming out, thus improving ride comfort. Route the air line tubing for the springs to your vehicle's bumper to provide easy access to the manual inflation valves.

Firestone Ride-Ride air spring components

Air Spring Construction

Firestone's double-convoluted Ride-Rite air springs are designed to give you maximum load support and enhance the performance and ride comfort of your vehicle. The rubber springs provide cushioning between your suspension components and operate at up to 100 psi. The springs have four layers of reinforced rubber to ensure durability and enhance load support. A braided wire girdle creates the double-convoluted shape of each air spring, increasing the burst pressure of the spring. The rubber springs are attached to corrosion-resistant metal end plates with a time-proven, rolled crimp seal that keeps the bags securely anchored.

Air Spring Installation

Each Ride-Rite kit includes custom-fit brackets that connect to your axle and frame. The brackets provide the mounting points for the air springs. Drilling may be required for some applications.

Great product, I ordered this for a 1998 custom e350 running 2010 king ranch gear meaning the running gear, since I couldn’t go with the kit specific for my van due to the fact that I converted it to 4x4 I ordered this kit. I did have to drill some holes since it was not specific to my rig, but that was no big deal just used a step bit. I also had to cut a bracket and reroute my emergency brake line, but hey I knew it wasn’t gonna be super easy. Any way kit is superb bags are top quality. The kit comes supplied with everything you need


See Last Review. Both are related.

unit is a good option but I’ve never been able to track down a troublesome air leak that slowly releases the compressed air over fifteen minutes. It’s a very annoying problem. Beyond that the unit was relatively easy to install although I made some specific upgrades to mount the compressor in a manner that leaves the fuel and brake lines in there original position so they didn’t need to be twisted up and out of the way. I used a 4” c-channel to firmly attach and mount the compressor over the undisturbed lines. Works great with less risk. I wish I could find the micro air leak and fix it but am at a loss as to how I might do that. I’d gladly try to spray some kind of stop leak into the air lines if I didn’t think it might screw the whole system up. In the end I’m not sure I would install this system if I had to do it all over again. I may ultimately remove it and reinstall the original rubber stops on the fra I’m since I no longer have my RV trailer anyway.

You mentioned that you wanted to find the micro leak and I wanted to ask if you had tried the soapy water technique? Where you would spray soapy water onto the lines -being careful of course- and see where bubbles form.

2008 Ford F-250 Super Duty

Put on 2008 f250. With a B&W turnover ball. Had to remove one bolt on both side of B &W to mount top bracket then replace with new bolts in kit No big deal. Put both sides on and ran the air lines in less than 2 hours. Had a leak on driver side. It was where I didn't cut the air line straight. Recut air line and that fixed the problem. I would recommend this to anyone.

Chevrolet Silverado 1500

Great product. On truck a year now with no leaks or other problems. I put a tee in the air line with a ball valve on one side so I could air them up evenly every time. My fifth wheels tongue weight is 1500 lbs and truck rides level with 20 lbs air.

2000 Ford F-250 Super Duty

Very easy bolt on kit. Probably took 2 hours to install. I am really excited to be able to fine tune the rear suspension when towing


Been driving around with the airbags for over half a year. Improved ride, but I especially noticed better ride quality with 5th wheel RV coupled. Excellent help from E-trailer. Always quality service with these folks.


The ride-rite air supenion works great. Very glad I put them on. Thanks

2003 Ford F-250 and F-350 Super Duty

Great product! Detailed instructions and step by step install video that makes the install smooth. Customer service was amazing! From the beginning of the order, to when it arrived. Great company! Definitely a repeat customer.


Had installed with a mechanic only due to not having all the right tools. Which was good because there was a gooseneck plate that I wasn't aware of that needed more attention than the usual install. Only complaint was that there should of been a "T" splitter for the air line to fill both at the same time. Other than that ride has improved.


Appears to be high quality. All parts and hardware included. Step 5 could confuse installers where saddle bracket is called “bottom of lower bracket” and lower bracket is referred to as “upper bracket.” Also in step 5, it is difficult to ascertain at which point alignment marks should be made.


Love my airbags. The installation videos are awesome. Had no problem installing them all by myself.

2010 Ford F-250 Super Duty

I have this product on a Ford F-250. Have towed a 34 ft Fifth wheel Trailer more than 10,000 miles this past year and the air bags have worked great. I keep 50lb when towing and 15lb when my Fifth Wheel is parked. Have been very happy with all product and service from etrailer

Ive been very happy with the product. We have put 30,000 miles on the truck since purchasing the air bags and it has improved the drive tremendously with hauling a trailer. Thanks for following up.

2004 Ford F-250 and F-350 Super Duty

went to install. had the wrong air fitting in the box. called e trailer and talked to an associate. told them what was going on. nothing ever happened no part or email. nothing

Thank you for bringing this to our attention! Our Customer Service team will be reaching out to you in the near future.
-- Etrailer Expert Brooke M - 08/31/2021


So far so good. Love the air bags. Would have been a 5-star review but one of the push in fittings failed on the left side, air supply tube. I had to get a replacement from the local BST (big scary truck) store. Swapped it out and no further problems. Hope they last because I like and need them on my 2009 F250.

2004 Ford F-250 and F-350 Super Duty

It was shipped and arrived in good time. The install was okay. But had one of the air fittings was the wrong size for the airbag,had to go to town and get a reducer,so made it work. As we are trying to leave for a trip tomorrow.

Thank you for your review. would always like to know about a defective or damaged item received prior to installation.

2011 Ford F-250 Super Duty

I put the load levelers on a 2008 F250 SuperDuty (diesel). It took me about 4 hours per side, on the grass with no lift or power tools. I could probably do it in two hours per side the next time.
The instructions are terse, but correct - the 2011 Ford F250 video was very helpful and resolve all my questions except for one.
The bladder(s) have an forward/rearward bracket positioning option constituted by two positioning nubs on the bladder top, and 2 mounting bolt holes on the bladder bottom. I was confused by the positioning option until I actually tested bladder positioning on the installed brackets - the brackets don't line up exactly, so the positioning option was actually a good thing. You have to choose forward or readward depending on how your brackets line up. If your brackets line up perfectly then you still have to choose.
I used the levelers on a couple of heavy trailers on fairly long hauls and they work as I expect them to - they: are easy to inflate/deflate, keep my bed level and support a heavy load, and keep my headlights out of everyones eyes.


This has been a great addition to my truck. Pulling the fifth wheel became so much nicer, should have done it much sooner. Suggest installing with the onboard compressor.


Product was an excellent addition to my 2009 F250. Install was straight forward and arrived at my house quick. Instructions were clear and is easy for anyone with basic mechanical skills. End use is for extra support with my travel trailer and levels my truck when hitched up. Airbags are easy to adjust with a hand pump you would use to air up basketballs, footballs, etc. I will continue to purchase from etrailer in the future. Great company.


Great customer service response, excellent products and the parts arrived on time.
This is my second purchase from them and I will undoubtably be returning for more.

2008 Ford F-250 and F-350 Super Duty

Installation was straightforward, I highly recommend watching the install video several times before you start. If you can put it on a lift or jack stands would be recommended as it's pretty tight getting under there to work. I didn't realize this until I started to run the air lines but take the spare tire out before you start! it gives you more room to move around and work. It probably took me about 6 hours total over 2 days but some of that was redoing a few things (don't forget the washers!), dealing with a stubborn bolt and double checking everything. Only got to take it on a brief drive with 70psi unloaded, it drove much better and wasn't too rough until I hit a couple dips, was a bit bouncy but expected. Can't wait to get the trailer hooked up and take it out!


Easy to install and really helps support the dump trailer that I haul behind my f 350


Had to get these as they're the only ones that work with my B&W gooseneck hitch. The brackets that mount onto the axle seem to be on the weaker side. I have hauled m trailer once with these and so far so good. Time will tell.

Ford F-250 Super Duty

Bought the Firestone ride rite for my F250 super duty for pulling 40’ fifth wheel. Very good instructions, very easy installation and it adjusts and works great. High quality material and perfect fit. Yes, I’d buy it again.

2009 Volkswagen Golf

Installed on a 2009 F-250 SD. Installation was difficult. Only because I didn't have access to a lift. Product is well built. It provides the rear suspension support I was looking for. Added bonus is my 3/4 ton rides smoother now. I pull a 35 foot travel trailer and a golf cart in the bed of my truck. I noticed the added weight of the cart was lowering the back end of my truck and affecting the steering. Not much, but enough where I needed to do something.

There was one problem with the instructions/diagram. When assembling the bottom bracket pieces, the diagram showed the bolt heads on the outside. I had to reverse them in order to clear the jounce stop to get proper alignment with the top bracket. See photos.

I also found a leak on one of the connections on top of the drivers side air spring. I pressured both springs to 40 pounds and let sit over night. There was a 20 pound drop on drivers side the next morning. I applied a kids bubble solution with a syringe ( works great) to find the leak. since there is sealer on the threads, I just gave it about 3/4 turn. Problem solved.

Overall, I think this is a great product which I would recommend.


The lift kit came in quickly, they asked for pictures of my rear frame just to make sure it would fit my unit. Very good customer service, I plan on buying from them in the future. Thank you etrailer!!
