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.

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.


Installed on my 2021 Toyota Tundra, These Firestone Ride Rite are phenomenal. I’m very pleased with the results AAAA++++


I ordered air bags from another company. They didn't sent them for over week. Frustrated I ordered same set of air bags from etrailer got them two days early. I've installed them and the other company still hasn't responded to the cancelation. let alone Sent the products I payed for and still waiting for a refund. I've have ordered several times from etrailer every ordered on time or early I really appreciate the attention to detail


Perfect fit! Easy to install. What a difference in ride and towing. Love the adjustability and eliminated the rear sag with towing my camper and dump trailer in my 2016 trd pro tundra.

2016 Toyota Tundra

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.

Still working great. I have them on my 1999 Ford too and those still work great.

2011 Toyota Tundra

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.

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.

Missing upper brackets. The instructions stress, the importance of these brackets, but they are missing…

I am sorry to hear that you are missing those brackets! Let me get you over to customer service so they can get them to you.

Shipping was quick and the product worked as expected. My only suggestion is to include recommendations on how to remove the existing leaf spring bumper prior to installation. I referred to a YouTube video to get an idea on how to remove. Otherwise, the installation was easy to complete.


Outstanding product!!! Well made and easy to install on my 2010 Tundra TRD. Just basic tools needed so anyone can do it!! Take your time and it is a fun 2 hour project. Made towing my trailer so much nicer. Level ride with comfort and good maneuverability. Think I am going to add these to my other GMC work truck as well.

Outstanding! Towing for a year now and all is fantastic. Level ride makes towing more safe and pleasant!
John T - 06/26/2021


Works great. My camper rides so much better now that I can level my back end. Definitely recommend!

1 year into the use, I’m super pleased with the air bags. Towing, braking, and most importantly, backing into my driveway. The transition from the road to the lift up, I don’t scrap the hitch because the air bags keep the truck backend at the proper height. Don’t think twice, buy them. I’ve even stopped a guy at a gas station to show him because his truck was sagging.
Cisco - 05/13/2023


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.

2020 Toyota Tundra

Item was shipped promptly, but when it arrived the box was obviously opened, and a lot of parts were missing! It’s easier to say what was included - 2 air bags, 1 soil of cut red air line, plastic mount. No metal brackets, hardware, air nozzles, instructions, warranty card, etc.

Ask for replacement. Return ship label and replacement part shipped promptly. Will update. Currently 1/5

2017 Toyota Tundra

I really like the product and your selectiin and pricing is good. The delivery wasn't so good as the carrier that you used delivered the package to another house a mile away and not even on my road. My address is; 20 S Fork Eagle Mtn Rd Columbus, MT and the package ended up at 639 Highway 10 Columbus, MT. The person whose house it was delivered to tracked me down in Facebook. Thanks!

2015 Toyota Tundra

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.


This air suspension shipped without packaging. Just a bunch of hardware rattling around in the box. When I asked trailer to replace it, they declined. So keep your fingers crossed that none of the pneumatic connections are damaged when you're going down the road with your trailer.


It was a nice simple install and gives you the ability to adjust the firmness to the rear of your truck when towing. They take some of the cargo weight away from your rear springs.

After a year of use, I appreciate having the helper air springs. Im able to take some of the load the leaqf springs would have to carry and move it over to the air springs. I know it will help extend the life of the factory leaf springs. I like the way it helps keep a firm suspension and level truck ride. When Im done towing, I just air them down till next time.
Chuck i - 01/19/2023


These work great. No problems after one year. Made a big difference with 1020 lbs. tongue weight. I don't see any difference in ride when unloaded (10 psi on helpers), Really nice to have the boat tow level.


This product has been stoudt. No issues, no problems when driving with no trailer or fully loaded with the 32 foot trailer.


Does every thing that it should do love it. Thanks for a great product

It’s not a year yet but they work great and can be filled up with bicycle tire pump and is more precise than an air pump and bike pump is easier to take a long then a compressor just thought you all would like to no thanks for a great product and good people to work with
Harvey - 03/12/2023


Always a great product and experience with etrailer! You are nuts if you buy elsewhere!

2011 Toyota Tundra

I purchased the helper springs for my 2011 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.

2010 Toyota Tundra

Install on 2010 Toyota Tundra CrewMax. Took about an hour with basic hand tools. Instructions are straight forward. Now truck doesn’t sag when towing.

2018 Toyota Tundra

Great product, easy install. Super packaging and instructions. 2018 Toyota Tundra Crewmax all ready for towing the Ranger around

2015 Toyota Tundra

Easy to install. Makes towing with my 2015 Tundra so much nicer.

2014 Toyota Tundra

Excellent product, and a great solution to our “squat” issues while towing our RV. Two suggestions to buyers. 1) Wash your undercarriage before installation! I looked like Pig Pen before I was done and it took a couple of hours to get the grit out of my teeth! 2) Test fit both upper plates to your frame before pre-assembly of the units. The plates could go on in any of 4 different orientations (up or down, left or right) and it’s much easier to figure this out beforehand than when you’re trying to wiggle the assembly into place and worrying about the alignment stud.
