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.

2011 ToyotaTundra

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.
Lloyd K - 08/05/2021


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.

2016 ToyotaTundra

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.
Robert N - 01/06/2018


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


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.

2010 ToyotaTundra

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.


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.

2014 ToyotaTundra

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.

2007 ToyotaTundra

Easy to install with all the right parts. I do wish they would ship it with a hose tee to tie the lines together. Makes airing them up much easier.


I installed this kit on my Toyota Tundra and it has worked great. Awesome product.


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


Since I installed this Firestone Ride-rite Helper Springs (airbags), I have had a better ride pulling the Air Stream trailer across this country. This product even works really well without a trailer too. I'd recommend it to any truck owner.

2011 ToyotaTundra

Very straight forward. Had no problems with install!


Straight forward and easy to install even for a girl!! HA! So far so good but haven’t test-driven the Tundra yet hope to do that today.


Installation was easy. I use the Firestone suspension when I tow my fifth wheel. I can raise the truck back up to level with a load on the hitch, and ride is much improved.

Still working great. I run with about 45 to 50 psi pulling Grand Design with 2019 Tundra, 6 psi unloaded.
Larry R - 08/09/2021


Makes all the difference in my 2019 tundra when hauling anything heavy. I haul a 30ft camper maxing my weight out and with these bags my truck doesn’t even squat an inch.

2015 ToyotaTundra

They work great and easy to install. 2015 Toyota Tundra 5.7 pulling an 8600 lb travel trailer.


These are great for my 2020 Tundra. Had a saggy bum while towing my 30’ travel trailer. Fixed it right up. One thing I’m trying to find out is if I can put the truck on a two-post lift and have the suspension hang the whole way down without stretching the airbags too much. Also, great service!! Needed the parts for a long haul camping trip, they were out of stock. ETrailer got them in and shipped right away!

2017 ToyotaTundra

Install was straightforward with some help from Youtube. I haven’t loaded it with the trailer yet, but have pressurized to 70psi with no issue. So far extremely happy with this product.


instructions were great and made the job easy. They also work perfectly at keeping the truck level while hauling our travel trailer.


The parts I ordered got to me very quickly with every single thing I would need to complete the installation. It took me much longer to do the install but that may be because I’m 80. Once done the air bags worked great & noticeably improved our trucks handling.

After a year or so of use I’m convinced they are a big improvement & I’ll also install a set on my next truck

Volvo Cross Country

This kit was super easy to install. Matter of fact I did the install in the driveway of my in-laws with a basic tool kit as I found I needed these to provide a more pleasant towing experience when I was moving cross country. The hardware was very nice and the tubing and fittings were very easy push connect type. Instructions are well laid out and straight forward. These also are very beneficial for flexible needs. When I don't have any large load in the bed or when not towing, I keep them at about 7lbs and you basically have factory ride but with less roll in turns. When you are loaded up, just add air to level out and ride comfortably (any truck loaded to full capacity will squat and the steering and driveability is fairly compromised at that stance.)

I like them more the longer I have them. I do my own projects around the house and these are handy for the heavier stuff that you are gonna haul from the point of purchase to the house. Keeps the truck level and helps utilize all of the capability of the truck drivetrain and frame.

2015 ToyotaTundra

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.

2016 ToyotaTundra

The product is great. It came on the the day it was promised with the correct parts. Although I consider myself mechanically inclined, it took me about 4.5 hours to install it on my 2016 Tundra. I do check and recheck a lot and I’m 72 years old. I put the truck up on jack stands, removed the tires and left the spare tire in place. That really restricted my movement under the vehicle and I found I had to contort myself a number of times in order to install and visually check the installation. I did remove the spare tire during the air line installation and that made a huge difference. It took me about 3 hours just to do the drivers side alone. The passengers side went pretty quick. Also, getting out from under the truck on numerous occasions to get the right tools took a lot of time.
Putting it on a lift and removing the spare tire certainly would’ve made it a lot faster.

Still working great
