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.

  • Suspension Enhancement Recommendation for 2008 Toyota Sequoia Towing Trailer
    The Timbren kit part # TTORSEQ1 that you referenced is the correct fit for your 2008 Toyota Sequoia and would give you additional suspension support when towing. That said I wouldn't necessarily recommend this kit unless you were planning to be towing most of the time as it would make the ride quality a bit harsher when not towing. The better option if you are concerned about ride quality is the part # F4164 which allows you to use varying air pressure in the bag so that you can tailor...

  • Does Upper Spring Seat Still Get Drilled if Installing Firestone Coil Rite Upside Down
    Hey Blair, if you were going to install the Firestone air bag kit part # F4164 upside down then cutting the hole in the top of the spring seat would not be necessary but this is not the recommended way to do this so I would lean on recommending you do it the way the instructions describe. Is there a reason you want to install it upside down?

  • Rear Air Bag Suspension Enhancement Recommendation for 2016 Toyota Land Cruiser
    For air bag style of suspension enhancement that fits your 2016 Toyota Land Cruiser the Firestone Coil Rite kit part # F4164 is a confirmed fit and will work well. This fits into the coils on the rear suspension which will then give you the additional support you need.

  • Comparing Suspension Enhancement Colors for 2013 Toyota Sequoia
    The Air Lift and Firestone Coil-Style air springs that fit your 2013 Toyota Sequoia are different colors so that they do stand out actually. Coil-style springs install inside your coil suspension so they are a bit more hidden while standard air bags install above the axle so they are seen a bit easier. If you want suspension enhancement that is a black color then I recommend the Timbren kit # TTORSEQ1. This simply replaces the factory bump stops on your vehicle so your suspension gets...

  • Are Firestone Coil-Rite Air Bags the Same Dimensions as Air Lift Springs for 2008 Toyota Sequoia
    Yes the Firestone Coil-Rite springs, # F4164, have nearly the same dimensions as the Air lift springs, # AL60786. This is because they install the same way and same place and are custom fit products for the 2008 Toyota Sequoia. If you are debating on which system to get, Firestone is the way to go. Firestone is a leader in the industry and they make a good, quality product. The Firestone bars are 5-1/2 x 10 inches and the Air Lift bags are 5-3/8 x 9-1/2 inches.

  • Recommended Suspension Enhancement for 2018 Toyota Land Cruiser
    I can see why this must be a bit frustrating, when the vehicle is supposed to already have the enhanced suspension features, but I do have something that can help you. You can add the Firestone Coil-Rite Air Helper Springs # F4164 to help add some leveling, and will fix the sway (jello like feeling you described) on your 2018 Toyota Land Cruiser. These are easy to install and they'll provide you with a certain level of customization since the air bags can be filled to provide as much or...

  • Can Coil-Rite Air Spring Be Mounted With Air Line At The Top On 2010 Toyota Sequoia
    I took a look at the installation instructions for the Firestone Coil-Rite Air Springs part # F4164 for your 2010 Toyota Sequoia. It does show that the air line should be at the bottom of the air spring when installed. I spoke with another Expert about the instructions and they told me that they called Firestone and was told that if you are able to install the Coil-Rite with the air line at the top it would not make a difference in the performance. If you have a kink in the line or...

  • Replacement Air Line Kit for Firestone Coil-Rite Air Helper Springs F4164
    Thank you for purchasing Firestone rear air bag kit # F4164 for your 2015 Toyota Sequoia that has coil springs. To replace the damaged air line you can use kit # FWR17600048 which is 18-feet of air line hose that is already equipped with the 1/4-inch threaded brass fittings. It can be tough to remove the air line from the fittings since their friction fit is intended to help prevent accidental disconnection.

  • Will Firestone Air Helper Springs Work With 2016 Infinity QX80?
    The Firestone Coil-Rite Air Helper Springs - Rear Axle # F4164 is compatible with all models of the 2016 infinity QX80. The Air Lift Load Controller Compressor System for Air Helper Springs- Heavy Duty - Single Path # AL25854 is also my recommendation for adjustability at your fingertips.

  • Air Helper Springs for 2008 Toyota Sequoia Limited
    I checked with Air Lift and their Air Lift 1000 # AL60786 are only confirmed to fit the SR5 model of the 2008 Toyota Sequoia. The Firestone Coil-Rite Air Helper Springs # F4164 will fit all models of the '08 Sequoia and will work for you. These springs fit inside your Sequoia's coil spring suspension and allows you to adjust the air pressure between 5 psi and 35 psi. Addtionally, the Firestone Union Tee # F3025-1 is available for the 1/4" hoses.

  • Dimensions Of Firestone Coil Rite Air Helper Springs F4164 For 2015 Toyota Sequoia
    I would be happy to help, but I will need to know the inside dimensions of the new springs on your 2015 Toyota Sequoia to recommend the correct air helper springs for you. The Firestone Coil Rite Air Helper Springs # F4164 designed for the factory coil springs on your Sequoia measure 5-1/2" wide x 10" tall, so as long as that is the same or very close to the size of your new coil springs this would still be a great option. If you need a different spring just let me know. I included a...

  • Replacement Air Line and Fitting for the Firestone Coil-Rite Air Helper Springs
    Justin, sorry to hear about all of the issues you're having. I don't see any real remedy for the situation other than to just replace the air line with the Replacement 1/4" Hose with Fittings for Firestone Coil-Rite Air Helper Springs # FWR17600048 and the push to connect connector # F3079-1.

  • Is There A Confirmed Fitting Coil SumoSpring For A 2010 Toyota Sequoia
    SuperSprings doesn't currently have a confirmed fit for Coil SumoSprings for a 2010 Toyota Sequoia, but you can measure to see if one of their models will fit. While the vehicle is on the ground with weight on the coils you'll need to measure the distance between the coils in the center of the spring. Once we have this dimension we can look for a compatible match. If there isn't a compatible match then the only other option to stiffen up the coil springs would be to install Firestone...

  • Can Firestone CoilRite Air Springs Be Used w/ Timbren Helper Springs on 2020 Toyota Land Cruiser
    You could add the Firestone # F4164 Coil-Rite Air Helper Springs to your existing setup, but I don't believe they'd do you a whole lot of good. When the Timbren # TTORLC2 Aeon springs are installed, you'll have about 1/2 to 1-1/2 inches of preload between the spring and the and the top surface of the axle tube. Once the suspension compresses by that amount to take up the preload, the Timbren springs will come into play. In other words, the only time the # F4164 Coil-Rite springs would...

  • Correct Air Bags for a 2014 Toyota Sequoia Limited
    If you're looking for air bags for a 2014 Toyota Sequoia Limited I recommend the Firestone Coil-Rite Air Helper Springs part # F4164 which I confirmed with Firestone are an exact fit. These air bags will work great to provide extra support while you are towing or hauling. They are straightforward to install and don't require any modifications. I checked with AirLift as well and they haven't been able to confirm fit yet on a Limited model.

  • How To Help Prevent Rear End Sag While Towing with a 2016 Toyota Land Cruiser
    I have two option to help decrease rear end sag on your 2016 Toyota Land Cruiser while towing, the Timbren Rear Suspension Enhancement System part # TTORLC2 or the Firestone Coil-Rite Air Helper Springs part # F4164. The Timbrens are a one time only install whereas the Firestones require adjustments. That said, these adjustments also mean you can really fine tune your setup for the perfect amount of support/comfort. If you will be towing multiple times a week then you most likely won't...
