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.

Review from a similar Ride-Rite in Vehicle Suspension


Installation was not hard at all, I definitely recommend having an impact wrench handy though. The airbags definitely improved how my toy hauler towed!! They took out all sag and reduced the roughness on torn up highways. The pic shows my truck back to factory ride height with the bags. 665369

I have traded this truck since then, however they improved my ride and stance every time I pulled my trailer.

Review from a similar Ride-Rite in Vehicle Suspension


Opened the box and in awe, I called my service guy, but he couldn't get to it for a week, so I started in. Rolled my truck up on some blocks. Removing the stock rubber bumper was easy. Then the installation. Bolting the upper housing onto the frame was the first job and was easy, except I forgot to include the spacer. So two steps later I had to unbolt it , insert the spacer and re tighten it. The rest of it went well and is now ready for the air line. Quit for the day and this morning will install the other side, which should go much easier now that I have learned from the first side. So it looks hopeful that even I can accomplish this. As a 75 year old retired surgeon that is saying a lot! Stay tuned for next installment which should review performance. 483120

Review from a similar Ride-Rite in Vehicle Suspension


I don't typically do reviews but I was so excited about these I just had to share. installation was fine, it took me about 2 hours. Watch the installation videos, it helps. I thought I needed a 3/4 ton truck just to put some heavy loads in my bed a few times a year, but not anymore! See the picture I loaded. that is my Silverado 1500 with approximately 1,500lbs in the back (there are a bunch of concrete curbs in the back). Can you tell, I can't. That's with only 30lbs of air in the springs. I have used air shocks in the past but forget that, no comparison. I will say I did not get the series to fill itself which I will probably upgrade to soon, but for now, these are exceeding my expectations. 603952

2016 Toyota Tundra Crewmax 4x4 - Installation was easy. Took about 1.5 hours. I pull a 27ft. travel trailer and these springs greatly improve the towing experience. Firestone Ride Rite air springs are a must have! 398929

These springs improved my towing experience. I would not pull a trailer using a half ton truck without using these springs.

Very good fitment, so you do get what you pay the premium for. My only concern is some sort of regulator would go a long way to getting the pressure equalized between the bags. This is not something I expected, but will probably add later to enhance the ease of use and warranted that fifth star. Highly recommend as advertised regardless! 635267

The air bags are the second purchase for this product for two different Toyota trucks in three years. I chose etrailer because they are thorough, always right and provide excellent customer service. The bags worked well with my bumper pull last year at around 20 psig and now with our new fifth wheel at 55 psig. Both sets of Firestone bags have been excellent. The Toyota Tundra pulls our Grand Design very well. We drove from South Carolina to New Mexico with no problems and a smooth ride thanks to etrailer and Firestone! 409027

Review from a similar Ride-Rite in Vehicle Suspension


Easy to install. Directions are great, as are the videos. I also ordered and used the T piece to make it easy. Just pulled my trailer and definitely noticed a difference. Very smooth over bumps. Just FYI, even at only 5 PSI (minimum recommended) it raised the rear of my truck almost an inch compared to the height before install. Not a big deal, but if you leveled the front of your truck like I did to get rid of the rake, you will now have some rake again. Not a big deal, but just be aware. I used the lift spacers (item F2536) because I have 1.5" spacer blocks on my leaf springs. I basically hook up the trailer or load the bed, watch the back end drop, then hit the air bags with the air compressor until the truck is level again. Rides like a dream. Would definitely purchase again. 454972


Comments
Still works great after a year. Definitely makes a difference in the ride quality when you have a heavy load. No leaks. I used the T so only have 1 valve to mess with. I like having the ability to dial in a little bit of rake in the truck Had previously leveled the truck by cranking the torsion bars in front, also have 1.5 blocks in rear. 2007 Duramax

2008 Chevy 1500. Using to assist with hauling travel trailer. Product shipped quickly and arrived on time. Poorly written instructions but easily installed once I was able to sort out the installation process. Very heavy duty material. Vehicle drove great after installation. Cant wait to put it to the test with a load. Note that the reference pictures on the website are of an older design. The mounting brackets have been redesigned and probably easier installation now. 141466

Great product well packed no damage and easy installation. Around two hours without impact wrench. Would recommend impact wrench. Differently would recommend to anyone who hauls heavy loads or trailers. Keeps truck level. Also and maybe must important Emily my customer service representative was very helpful, friendly, and great to work with very professional. Thank you for all your help. Have a great day and be safe. . 773364

Ask the Experts about this Firestone Vehicle Suspension

  • Why is the Ride in the Back Seat of an F-550 So Rough, and is There Anything That Makes it Smoother
    The crazy rough bouncing of the rear suspension is due to the very high spring rate of the rear suspension. The very high towing capacity of your early model F550 is kind of a double edged sword in that you have the ability to tow way more weight than almost any other vehicle on the road, but the suspension is so stiff that when you hit a bump you really feel it. The rear suspension of your truck was not designed for comfort, it was only designed for carrying a lot of weight. When your...

  • Air Suspension Enhancement That Fits 2019 Ram 3500 and 5500
    We have air bag style suspension enhancement that fits your 2019 Ram 5500 with the part # F2404 which will work really well to provide additional support to the factory suspension as needed since you can adjust the air pressure in the bags to increase or decrease support. That said, we don't offer an air suspension system replacement to convert the vehicles to air ride if that's what you were referencing. Then for the 2019 3500 Ram we have the Air Lift kit part # AL89231 as a confirmed...

  • Air Bag Kit and Compressor for 2018 Ram 5500 with Service Bed
    Best option will be an air bag kit like the Firestone part # F2404 which is a fit for your 2018 Ram 5500. This gives you ability to get the exact amount of additional suspension support you need on the heavier side instead of adding a leaf which might be too much or not enough with no adjustability. For a compressor kit you'd then want a dual path kit like the part # F2590 which comes with a heavy duty compressor that allows you to easily add air pressure to each side of the rear suspension...

  • Suspension Recommendation for a 2011 Ford F-350 Dually Cab and Chassis with a Gooseneck Hitch
    I spoke with my technical contact at Firestone and he advised me that, tentatively, the correct suspension kit that will fit your 2011 F-350 Dually Cab and Chassis is the Firestone Ride-Rite Spring # F2176. The Firestone Spring # F2404 will not fit your F-350 truck - it only fits F-550 trucks. The two issues that determine if # F2176 will fit are: first, you need to have 7-1/2 inches between the tire and the frame of your truck, and secondly, this set mounts on the outside frame of the...

  • Availability of Air Bag Suspension and for 2011 Ford F350 Cab and Chassis with Utility Body
    I spoke with my Firestone representative regarding an air bag kit for your 2011 F350 Utility Body. I was told that because most of those cab and chassis models had the fuel lines running along the frame right where the spring brackets would need to attach, they do not offer a specific air bag kit for that vehicle. I was told that if the fuel lines do NOT interfere, the # F2176 kit could be used. My representative recommends that you examine the diagram shown in the installation instructions...

  • Will Firestone Ride-Rite Rear Air Bag System Part # F2404 Fit 2013 Ford F-350 Dually Cab/Chassis
    This particular Ride-Rite Rear Axle Air Bag System, part # F2404, will not fit your 2013 Ford F-350 Dually Cab and Chassis according to my contact at Firestone. Instead you can use their kit # F2176 as long as you have at least 7-1/2 inches space between the top of your tire and vehicle. An adjustable air spring kit like the Firestone # F2176 is ideal if you will routinely tow a wide variety of trailers and/or cargo loads of different weights.

    Since your 2016 Ford F-350 dually is a diesel you would want the part # F2597 for a confirmed fit for your truck. I attached an install video that shows this kit being installed on a similar 2016 F-350 as yours as well. For a compressor kit to make maintaining and inflating the bags easy you would want the part # F2158.
