Firestone Coil-Rite Air Spring Basics

Firestone Coil-Rite springs fit inside your existing rear coil springs to maximize the effectiveness of your suspension system. The added cushion provided by the air springs allows your vehicle to better handle a heavy load or trailer. 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 for more effective braking and handling under heavy loading or when you encounter adverse road conditions. The air springs also help to level your headlight beams and reduce wear on your tires.

Adjustable Air Pressure

The air pressure in your Coil-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 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 Coil-Rite air spring components

Air Spring Construction

Coil-Rite springs are constructed of durable, elastic polyurethane to ensure years of service. Single replacement springs (sold separately) are available for maintenance to an existing Coil-Rite kit.


Air Spring Installation

The Coil-Rite springs install inside your existing coil springs. The custom-fit springs attach to your vehicle's spring seats.

  • Do I Need a Spacer to Install the Firestone Coil-Rite Springs on a 2016 VW Golf SportWagen?
    Hey Bill! The Replacement Air Spring for Firestone Coil-Rite Rear-Axle Kits 4167, 4168, 4176 and 4183 item # F6027 fits quite a few different air bag kits like the item # F4176. Some of these kits require a spacer. When you install the Firestone Coil-Rite Air Helper Springs item # F4176 on a 2016 VW Golf SportWagen you do not need a spacer, which is why there isn't a set included with the kit. The spacers are typically required when the air bags are mounted with the air inlet facing down....

  • Will the SuperSprings Coil SumoSprings Fit a 2015 Volkswagen Passat TDI
    The SuperSprings Coil SumoSprings, # CSS-1125, will fit your 2015 VW Passat TDI. You are correct that the Firestone airbag kit, # F4176, will not fit the TDI models, but based on the coil spring dimensions you provided in the attached diagram, these SumoSprings will work for you and help level the rear end of your Passat with the weight of the bike rack and bikes.

  • Alternatives for Trailer Hitches That Do Not Allow for the Use of a Weight Distribution System
    I do have ways to help with trailer sway and vehicle sag on your 2013 Volkswagen Tiguan but none of the trailer hitch receivers they have for your vehicle are compatible with a weight distribution system. Load leveling is what Volkswagen calls what we refer to as weight distribution. A weight distribution system is never going to be required however, if the gross trailer weight (GTW) of your trailer is more than 50% of the gross vehicle weight rating (GVWR) for your vehicle, the use of...

  • Is Air Compressor Required for Use With Firestone Coil-Rite Air Springs F4176
    While it is not a requirement, I do highly recommend using the Firestone Air Command I - Analog Gauge with Standard-Duty Compressor # F2158 with the Firestone Coil-Rite Air Helper Springs # F4176. The reason for that is the compressor is going to make it much simpler to inflate and keep the pressure of the air springs where you need it. The reason is, the springs come with manual inflation valves (see accompanying photo) that you need to find a place to route and install underneath the...

  • How To Prevent Sag On A 2023 Kia Sportage When Towing A Trailer
    To help prevent rear sag on your 2023 Kia Sportage, I would recommend adding rear axle air helper springs. For your vehicle we have The Firestone Coil-Rite Air Helper Springs # F4176 and The Air Lift 1000 Air Helper Springs for Coil Springs # AL29PD. Out of the two sets I would recommend The Firestone Coil-Rite Air Helper Springs # F4176 over The Air Lift # AL29PD because they have a better more durable construction and will last longer. The Firestone airbags have a load-leveling capacity...

  • 2015 Jetta TDI Firestone Air Spring Compatibility
    I reached out to my tech contact at Firestone and he let me know that the Firestone Coil-Rite Air Helper Springs - Rear Axle # F4176 are a fit for the TDI models as well. There was an exception for 2007-2010 where they did not fit, but the 2011-2017 TDI models do fit.

  • Possible Suspension Enhancement Fit for a 2014 Volkswagen Jetta SportWagen
    I spoke with my contact at Firestone and if the coil springs on your 2014 Jetta Sportwagen measure just over 3-1/2 inches in diameter and 7 inches in length when the springs are bearing the weight of the vehicle, the Coil-Rite Air Helper Springs, # F4176, will work for you. They haven't tested this kit on your vehicle yet so they don't know for certain if it will fit, but there is a good chance it will. These air springs fit inside your existing coil springs and help to level your vehicle,...

  • Will Air Bags Improve Ride Quality and Sag for 2012 Volkswagen Jetta SportWagen Towing a Trailer
    The best solution for sag and poor ride quality caused by towing a trailer is weight distribution and not suspension enhancement. But the hitches for your 2012 Volkswagen Jetta Sportwagen are not rated for weight distribution. The next best ting would be suspension enhancement. Firestone kit # F2158 can be used with Coil-Rite system # F4176 which fits your Jetta SportWagen. They will provide a better ride and decrease sag caused by carrying a heavy load. I have linked the installation...

  • Firestone Coil-Rite Helper Springs Leaking
    The Firestone Coil-Rite # F4176 system is covered by a lifetime warranty. Is the leak occurring at the spot where the line itself secures in the fitting, or where the fitting is installed in the air bag? It sounds as if you're leaking where the line enters the fitting. The junction between the fitting and the air line is VERY dependent on a good fit of the line in the fitting. If the line isn't fully seated, or the cut on the end of the line isn't EXACTLY perpendicular (or perfectly...

  • Diameter Of Air Line For Firestone Coil-Rite Air Helper System
    The air line that is included in the Firestone Coil-Rite Air Helper Kit, part # F4176, is 1/4 inch diameter. If you wish to purchase more air line, we do carry the air line by itself, part # F99ZR. This is a 22 foot long section of red tubing. The Tee you could use to split one line into two is the Firestone Union Tee, part # F3025-1.

  • Recommended Suspension Upgrade for a 2023 VW Tiguan
    Yes, there is one option to upgrade your 2023 Tiguan's suspension. It is the Firestone Coil-Rite Air Helper Springs item # F4176.

  • Installation Instruction Link and Durability of Firestone Coil-Rite Air Helper Springs # F4176
    The Firestone Coil-Rite helper springs, # F4176, are made of an elastic polyurethane and not a regular hard plastic so they can move and flex with the vehicle suspension and will last for years provided they are inflated as specified in the instructions, linked for reference, and not overloaded.

    Yes! The Firestone Coil-Rite rear helper springs # F4176 will fit your 2015 Volkswagen GTI. I double-checked the fit with Firestone. I have linked a video review of this system for you. To avoid having to find an air pump I also recommend adding an onboard compressor system # F2158 so you can adjust the air pressure from inside the vehicle.

  • Weight Distribution Alternatives for a 2013 Volkswagen Tiguan
    I do have options for you but if the owner's manual for your 2013 Volkswagen Tiguan states not to use a weight distribution system then we cannot recommend against this. If you would like a bit more support and stability then I recommend using the Firestone Coil-Rite Air Helper Springs part # F4176 which actually installs inside the coil springs and can be adjusted for optimum performance. If you're experiencing sway then I recommend using the Tuson Asymmetric Sway Control - 1 to 4 Axles...

  • Will Firestone Coil-Rite Rear Air Helper Springs Part # F4176 Fit 2013 Volkswagen Beetle Diesel
    According to my research the 2013 Volkswagen Beetle diesel came with either a 1.6L or a 2.0L turbo diesel. The Firestone Coil-Rite Rear Air Helper Springs Part # F4176 will not fit the turbo-equipped Beetle. However, we do offer a similar kit from Firestone that will fit the turbo-equipped 2013 Beetle, part # F4175. This Firestone Coil-Rite kit includes all parts required for installation (with no drilling necessary) and allows for manual inflation of the air bags. If you wish, Firestone...

  • How Long Will the Springs for a Firestone Coil-Rite System Last on a 2010 VW Jetta SportWagen
    The Firestone Coil-Rite system, # F4176, if properly maintained, should last the life of the vehicle. The air springs themselves have a limited lifetime warranty and all the hardware has a 2 year limited warranty. Firestone does build their springs to last which is why they have a limited lifetime warranty.

This kit's airbag will measure 3.56 inches in diameter and 7 inches long. The way the air bags are designed is to sit loosely in the coil spring, they will not need to touch the top and the bottom when uninflated. I also recommend adding an onboard compressor system # F2158 so you can adjust the air pressure from inside...

  • Hitch Suspension Enhancement and Brake Controller Recommendation for a 2012 VW Golf TDI
    You cannot safely modify a Class I hitch to match the capacities of a Class III hitch (even though my oddball uncle did somehow weld a Class III hitch opening on his Mazda Miata...NOT RECOMMENDED). Hitches are given capacities that generally reflect what the towing capacity of the vehicle they are installed on. Even if you did somehow reinforce a hitch to be stronger, the attachment points on the vehicle's frame can't be made stronger and this is typically the weak point. The Draw Tite...

  • Suspension Enhancement Recommendation for a 2012 Volkswagen Jetta Sportwagen
    At this time there is only a Firestone air bag type of suspension setup available for your 2012 Volkswagen Jetta Sportwagen. For that you would want the part # F4176. The Firestone and Air Lift bags are both made by the same company though either way you would basically be ending up with the same components. Your other option is the part # CSS-1145R which installs in between the coils of the springs to provide additional support. What's nice about this kit is that it does not require you...

  • Firestone Coil-Rite For 1969 AMC Rebel With 5" Inside Diameter 15" Tall Springs
    Hello Troy, thanks for reaching out. I do have one potential option for you, but truth be told, there are not going to be any Coil-Rite kits that are "confirmed" to fit the springs in a 1969 AMC Rebel. Looking thru the Firestone catalogue, they only make one Coil-Rite kit for a 5" diameter spring. This would be Firestone part 6134 which is a 5" diameter 11" long type E spring. Unfortunately, this is not a kit we carry here at etrailer, so you would have to go directly thru Firestone to get one.
