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 you have a question about this Vehicle Suspension?
  • Will Firestone Coil Rite Air Helper Springs Prevent Tire Cupping or Leaning
    The Firestone # F4170 is designed to help suspend cargo carried in the rear of your Hyundai Santa Fe. There are several possible causes for tire cupping. I'd recommend having a tire shop examine the tires, suspension and alignment for anything that's worn, damaged or out of adjustment. You mention that the wheels are leaning.. this could indicate failing wheel bearings. I'd urge you to get your vehicle checked out by a mechanic. A suspension enhancement product will NOT increase the load...

  • Troubleshooting Suspension Noise After Air Bag Installation In Coil
    Typically the noise you hear after installing coil springs like the # F4170 is from the metal coils of your suspension rubbing something as the suspension moves. I had this happen on my car once when I installed air springs in it and the problem was that the rubber isolator at the top of the spring was positioned in such a way that it was allowing the metal coil of the spring to touch the frame of the vehicle. When the suspension moved noise was created. I had to go back and reposition...

  • Installation Video for the Firestone Coil-Rite Air Helper Springs # F4170 on Hyudai Santa Fe
    The only install video we have for the Firestone Coil-Rite Air Helper Springs # F4170 that you referenced is on a 2005 Hyundai Santa Fe. I can assure you the install process will be the same for your 2014 Santa Fe. I attached a link to the video to the right.

  • Replacement Elbow Fitting for Firestone Coil-Rite Air Helper Springs
    I spoke with my contact at Firestone regarding the Coil-Rite Air Helper Springs # F4170 you have installed. He stated that the Replacement Schrader Valve Fitting # F3438 will indeed fit the air bag and air hose on your system. This will work nicely to replace the original fittings.

  • Coil-Rite Air Bags are Noisy on a 2014 Hyundai Santa Fe
    Water doesn't make a good lubricant but it could help temporarily with squeaky things. Regardless this is the first time I have heard of this issue. It is possible that the air bags are not all the way seated or they could be inflated beyond the maximum, which is 35 psi for kit # F4170. Or you may need to try more or less air pressure (as long as you stay within that 5 to 35 psi range). I am wondering if the bags are making significant contact with the coil springs. They will touch it...

  • Firestone Coil-Rite Air Bag Inlet Thread Size
    I'm sorry to hear that you're having issues with your Coil-Rite system. The bag inlet thread on the Coil-Rite # F4170 for your 2014 Hyundai Sante Fe is a 1/4" female NPT fitting. The Firestone Replacement Schrader Valve # F3438 is going to be a better fitting than the fitting that came with the # F4170 and is meant to combat some of the issues that you may be having with the connection.

  • Towing Capacity of 2007 Hyundai Santa Fe and Recommended Suspension Enhancement
    I checked the owner's manual for your 2007 Hyundai Santa Fe and there are a few towing capacities listed, depending on your vehicle's engine size and whether or not it has a factory trailer package. If your Santa Fe does not have the trailer package, the listed maximum towable weight is 2,000 pounds. If you have the trailer package, the maximum trailer weight for a 2.7L engine is 2,800 pounds and for a 3.3L engine it is 3,500 pounds. I recommend checking with your owner's manual to confirm...

  • Helper Spring Options For A 2017 Hyundai Santa Fe
    While there aren't suspension enhancement options available for your 2017 Hyundai Santa Fe, if you use your vehicle for towing you could use a weight distribution system to level your setup. Firestone has suspension kits for previous years but there isn't one for 2017 models. A weight distribution system creates a level, stable ride when you tow a trailer. It will help keep your towing setup level and make sure the weight of your trailer doesn't cause undue stress on your vehicle. One...

  • Is the Jounce Bumper Mount Reused when Installing the Firestone Air Bags on a 2008 Hyundai Santa Fe
    When installing the # F4170 Firestone Air Bags, the jounce bumpers inside the coil springs on your 2008 Hyundai Santa Fe will need to be removed, but you will not remove the metal jounce bumper mount. I attached a drawing showing this and installation instructions for you to review prior to purchase. To remove the jounce bumpers you could use pliers to grab and pull them down at an angle or you could use a flat pry bar to get behind the jounce bumper and pry down at an angle. We did have...

  • Is Weight Distribution System Needed for 2009 Jeep Liberty with 1 Inch Rear Sag with Trailer Loaded
    For your 2009 Jeep Liberty with tow package you do not need to use weight distribution but we would recommend it because your trailer is over half the weight of your tow vehicle. There are benefits like reducing sag and adding sway control so it is a great option if you choose to. Based on your trailer weight when you calculate the 10-15% tongue weight and then any cargo weight behind the rear axle of your Jeep, I recommend using the Fastway e2 # FA92-00-0800. This system will use hitch...

    The Firestone rear axle air bag kit # F4170 is a confirmed fit for your 2016 Hyundai Santa Fe XL with front wheel drive. This same kit also fits the 4-wheel-drive version. The kit includes all parts needed for installation and manual inflation via the included Schrader valves. Installation is shown in the linked video. You can add at any time a compressor kit like # F2158 to allow for convenient automatic pressure adjustment from the comfort of the passenger compartment. Be sure to always...

  • Reducing Suspension Sag On a 2015 Santa Fe Sport While Trailer Towing
    I have a couple options for your 2015 Hyundai Santa Fe Sport. First is the Coil SumoSprings Custom Helper Springs # CSS-1125R which will increase the stiffness of your springs by 30%. This will help to reduce the sag you are experiencing both with trailers and if you load heavy objects into your Hyundai. For a more adjustable system you can look at the Firestone Coil-Rite Air Helper Springs # F4170. These will allow you to adjust the air pressure in your springs so you can dial in your...

  • Availability of Air Bag Suspension for 2014 Hyundai Santa Fe
    Firestone offers a suspension enhancement product for your 2014 Santa Fe. The Firestone Ride Rite Air Helper Spring system, part # F4170 would be inserted into your existing coil springs to provide more suspension support. The air bag system allows you to add more air to the system to make the ride firmer, or release air to soften the suspension. Keep in mind that the Ride Rite system won't change the cargo carrying capacity of your Santa Fe. To see the installation details, click the...

  • Recommended Rear Suspension Enhancement for Carrying Scooter on Rear of 2013 Hyundai SantaFe
    The Firestone # F4170 Coil-Rite Air Helper Spring kit is what I'd recommend. The single path system allows you to tailor the amount of support according to the load placed on your rear suspension. As you stated, the system won't increase the capacity of the rear suspension of your 2013 SantaFe, but it will greatly reduce the sag in your rear suspension that occurs when carrying your scooter. This system is a must in your situation, because when the rear suspension sags as yours does when...

  • Air Line Size and Union Tee Recommendation for Firestone Coil Rite Kits
    The air line that comes with the # F4170 is 1/4 inch line. For a union tee you would want the part # F3025-1. This will allow you to inflate both bags equally at the same time.

  • Will the Firestone Coil-Rite Air Helper Springs F4170 Fit a 2016 Hyundai Santa Fe Limited AWD
    The Firestone Coil Rite Kit part # F4170 will fit your 2016 Hyundai Santa Fe Limited that has all-wheel-drive. I attached an install video that shows the install process on a similar Santa Fe. We had a customer with an AWD model come back and say that he did have to remove the springs but that is not a step that is outlined in the instructions. Most likely it would make it easier though so I would recommend it. The Air Lift WirelessONE Compressor # AL25980 would be a great option to install...

  • What Tools are Needed to Install Firestone Coil-Rite Suspension on a 2013 Hyundai Santa Fe
    If you look at the isntructions I have linked for the Firestone kit # F4170 you can see what tools you will need. First, you will need a jack to jack up the vehicle, jack stands to rest the frame of the vehicle on, and wheel chocks to prevent the vehicle from rolling. You will also need a drill and a 7/16 drill bit. A tubing cutter is also recommended, # AL10530, because the air lines must be cut as straight as possible. You can push in the air bag by hand or by using a blunt tool such...

  • Alternative to Air Bag Suspension Kit for 2013 Hyundai Santa Fe
    The Firestone Coil-Rite Air Helper Springs # F4170 can be a bit tricky to mess with since it's an air bag that sits inside a spring. If the bags were punctured during use then your best solution would be to use the Coil SumoSprings for your 2013 Hyundai Santa Fe instead. It looks like you have a 4x4 so you'll need the kit # CSS-1125R unless you have a GLS or Limited - in that case you'll need the kit # CSS-1145R instead. These insert between the individual coils on your OEM spring suspension...

  • Does Firestone Air Bag Kit Fit 2014 Hyundai Santa Fe
    We know the Firestone air bag kit part # F4170 is a fit for your 2014 Hyundai Santa Fe because we had the chance to install them on a similar 2015 and 2013 model and they fit and worked well. If you check out the install video I attached below you can see the install. Or you could show it to your Hyundai dealer so that they can see how it would install too.

  • Troubleshooting Pinched Airline with Firestone Coil-Rite Air Springs on a 2008 Jeep Liberty
    The hole that gets drilled into the jounce bumper mount does not have a set measurement on where it should be located. If shortening the line would prevent it from getting pinched when the suspension is lowered I would do that as that should be the easiest. Since you plan on shortening the line what you could do is cut a slit in the air line on the barbed fitting to remove the line and then cut the line to the length you want and reinsert the line. Thanks for the feedback on drilling...

  • Does 2007 Hyundai Santa Fe Jounce Bumper Need to be Removed to Install Firestone Air Springs
    The jounce bumper will need to be removed prior to installing the Firestone Coil-Rite Air Helper Springs # F4170 on your 2007 Hyundai Santa Fe, but this is pretty standard with this style of air bag system. These are the only air bags that will fit your vehicle so there aren't any options that would be more heavy duty unfortunately.
