Firestone Vehicle Suspension
- F2445
Highlights
Custom Fit for Your Vehicle: Mounts to existing attachment points
5,000-lb Load Support: Keeps your truck level and steady when towing or hauling heavy loads.
Protects Steering and Braking: Prevents rear sag so handling, traction, and braking stay consistent.
Adjustable 5–100 psi: Lets you fine-tune air pressure for comfort unloaded or support under load.
Balances Uneven Cargo: Inflate each side separately to level off-center loads and reduce body roll.
Stay Level and Confident Under Load: 5,000-lb Rear Suspension Support
When heavy gear or a loaded trailer makes the rear end sag, steering and braking can feel light and unpredictable. The Firestone Ride-Rite Air Helper Springs add up to 5,000 lbs of load-leveling support between the frame and rear suspension. By keeping your vehicle level, they improve stability, steering control, and headlight aim while reducing strain on the rear axle. The result is confident handling and even tire wear every time you haul or tow.
Fine-Tune Comfort and Control: Adjustable from 5 psi to 100 psi
No two loads are the same, so these double-convoluted air springs let you dial in the pressure to match. Add air when towing or carrying weight to level off-center loads and reduce body roll; drop down to minimum pressure for a softer ride when unloaded. Manual inflation valves are included for individual side-to-side adjustment, giving you the flexibility to balance your setup exactly how you want it.
Built Tough for Real Work: Reinforced Rubber and Rolled Crimp Seal
Each Ride-Rite air spring uses four layers of reinforced rubber with a braided wire girdle that forms its double-convoluted shape. This boosts burst pressure strength while cushioning road shock and softening contact between the axle and frame to prevent bottoming out. Corrosion-resistant metal end plates are secured with a rolled crimp seal for a long-lasting, leak-free fit that holds up through years of hauling.
Straightforward DIY Setup: Hardware and Brackets Included
Everything needed for installation comes in the box—custom brackets, air line, hardware, and separate valves for manual inflation. The brackets mount between the frame and axle to provide solid anchor points for each bag, with drilling required on some setups. Add optional switches, gauges, or compressors (sold separately) for easy inflation from inside the cab once your system is in place.

Really quite easy installation. Honestly, the hardest part was routing the air line. (that coiled up hose!) I ended up covering the lines with cable wrapping to protect them from any rubbing or scuffing. I also don't have a compatable hitch for the mount, and didn't want to mount them through my bumper in the license plate area because I know I would step on them at some point in time. Product had all the correct parts, high quality, and super happy with it. I wish I had gotten them sooner. 3337723
Install looks awesome - I think the wrapping of the line was a great idea too! Do you work on vehicles a lot?

I do, mostly my own, not a professional, but have everything like tire changing and balancing machine, compressor, etc. Didn't need much to do this job which was nice though. just some wrenches, oscilating tool (For the factory bumpers), razor knife, and a drill with an assist from my creeper (To lay on, not my weird neighbor).

Best airbag kit on the market! Going on 10 years and 160k miles on one kit and a year and a half on the other (two different vehicles). Firestone’s quality is excellent, their customer service is exceptional, and the kit design is simple. Quality components means ZERO air leaks in 10 years when installed properly (cut the airlines at 90 degrees with an inexpensive airline cutter or brand new razor blade). Their mounting brackets are simplified, making more room for the airbag between the axle and frame. And the double convoluted bag offers better ride quality and more suspension movement than a single convoluted bag. I’ve run a single convoluted bag setup from another reputable manufacturer and noticed a marked decrease in ride quality and comfort. I also recommend installing cradles such as those from Daystar (also 10 years on a set) to allow 100% downtravel for maintenance or off-road articulation without fear of tearing a bag. Well worth spending a little more for this USA brand kit over the cheap Chinese copy-cat kits. I tow and haul regularly - weekly, if not several times a week - and these have stood up to snowy sub freezing winters, 100 degree summer days, dusty and gravely off-highway adventures, and general use and abuse that comes from working out of a vehicle for a decade. Can’t find a better kit. 3566003

It was an easy install and everything fit OK. I removed the spare tire to make it easy. I had to slightly bend the brake hose bracket on both sides and another bracket just slightly to clear the rear spring clamp at the bottom of the spring. I carry my 1,400 pound Honda Pioneer 700 and pull my travel trailer with a 400 pound hitch weight. I have your weight distribution hitch for some of the hitch weight. 270021
Still working great. I have them on my 1999 Ford too and those still work great.

Installed easily, and used them to pull a heavy 24’ trailer across the country with a half ton pickup. The only thing I’d like to see is a manual leveling system with gauges and a compressor on board. I use a hand pump specifically for motorcycle air suspension to make the fine adjustments required to set the pressure. Works well.
They did their job perfectly. 855930
After a year, they are a great aid in hauling a d towing with my half ton. No more sagging rear suspension when loaded. Yes, the rear ride firmed up a little even with only five pounds pressure. That’s a small trade-off.

These helper springs work well on my 2018 Tundra Crewmax. My truck is leveled and I normally carry 300-400lbs of tools in the bed with a truck cap, so I definitely get the Tundra sag/squat in the rear. These helper springs get my truck back to level. The ride is still smooth. Install was straightforward and the product videos on etrailer are helpful. Very happy with my purchase! 3515884

etrailer was very helpful with making sure I ordered the right product. As for the product... I love the addition to my 20201 Toyota Tundra TRD PRO. It made towing my 2021 Lance 2285 Travel Trailer a dream. The truck and trailer sit perfectly level now and the truck handles great. Easy install only took a couple of hours. In my pic... the stabilizer jacks are down because I was doing a quick overnighter and didn't want to unhitch. But the stabilizers aren't lifting the camper or truck.. just kissing the ground to keep the camper from rocking when inside. Its the only pic I had handy. 1514763
Toyota Tundra for leveling the truck while towing. It took me about 3 hours to install the helper springs and they work great. I attached a photo of my truck with my VW on a U-Haul to show how the helper springs kept the load level with about 50 psi in each helper spring. I pulled the VW a little over 2000 miles, from WI to WA, and never needed to add air (the photo was half-way through the trip). Unloaded, I keep about 5 to 10 psi in the helper springs and the ride is still very smooth. 50874
Installation was pretty straight forward. Completed in about 2.5 hours taking my time, in my drive with basic tools. Havent had a chance to test them out.

In the last year I’ve logged over 2,500 miles towing with the airbags installed. Tundra TRD Pro’s are known for their “squat” when hauling. These bags not only leveled the truck but also provided a noticeable difference in handling & driving. Only regret is not having them installed earlier. Self install was easy. 3200932

Just a little over a year now and these Firestone air bags are worth every penny. Two or three times a month I have a loaded trailer going somewhere. I simply level the truck back to normal ride hight and go. No lite front end, no squat in the rear, and the trailer and truck are right where they should be. I made two decisions I wish I had done different: first I didn’t put an onboard compressor nor gages. That’s going to get added soon. Second, if you choose to not put the onboard compressor then put a T connector on the lines to make inflatedeflate easier on yourself. I highly recommend if you are towing allot.

They're very nice, easy to install. I did it on a 2015 toyota tundra in about an hour from start to finish. I removed the rear tires to cut the joist off to make it easier for me. Other than that extra step I made for myself their videos for the install is spot on. I recommend them to anyone who is hauling anything of weight to save wear and tear on the suspension,breaks and tires of their vehicle. 822466

Installed a year ago and have used them many times towing the marching band trailer for the high school and my RV/Trailer. Easy to install, easy to use and they have made a huge difference in being able to put on my stabilizer bars and not scraping when backing my trailer into my driveway. Loaded up the truck with a pallet of concrete recently and did not have that terrible sag I had before. 1751342

Hello Craig,
I am sorry to hear that your first time pulling your 2023 Cougar 26RBS was not enjoyable.
With any WDH is making sure you are using the correct spring bars. You can figure out which ones you need by determining your loaded tongue weight. To get an accurate measurement, I recommend using the Big Truck Big RV Tongue Weight Scale w/ Storage Bag for Trailers - 2,000 lbs # BTBRV44FR. Typically, your tongue weight will be 10-15% of your total trailer weight. It definitely won’t... view full answer...
Weight distribution (WD) systems actually take on the weight of any cargo behind the rear axle of the tow vehicle (your 2010 Toyota Tundra) as well as the tongue weight (TW) of the loaded trailer. This is why you are finding that your WD system isn't performing as well when you load down the bed of your pickup.
For example, the Equal-i-zer # EQ37100ET has a TW range of 600 lbs - 1,000 lbs. If you were using this system and the 709 lb TW of your trailer plus the cargo behind the rear axle... view full answer...

Don't worry I can help.
The anti-sway unit that the dealer put on your trailer will not allow you to backup like you want to. This is because it is constantly putting force onto the trailer and when backing up it will be easier to jack-knife. This anti sway bar is an effective sway when used in the towing position because it makes the trailer want to track the vehicle.

I did some research on your Interstate 20 Super Coach trailer, and found that the trailer has an 8 inch I-Beam frame and most likely an adjustable channel tongue. This is the reason that you are having difficulty with the weight distribution system.

Hello Ryan,
The Firestone Ride-Rite Air Helper Springs part # F2445 for your 2015 Toyota Tundra will not require the use of spacers if the lift blocks are installed under the leaf springs because the distance between the top and bottom airbag brackets will not change because of this. In the past, Firestone has called for an Axle Bracket Extension like part # F2506 to be used to help support the weight with lifted applications but they have since done further testing and determine this... view full answer...

Hey Don, thanks for reaching out. It is weird that Firestone doesn't list the torque values in their instructions. I went ahead and included a list below that shows the proper torque specs.

The Firestone Airbags # F2445 do not have internal jounce bumpers. The airlift air bags are going to be the ones that are built with those internal jounce bumpers.
