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.

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.

installation instructions could be better When you deflate to work into spring, once you get one end in you should release the deflater stopper, makes it easier to work into place. Also, if you work it in from the top, once you get it mostly in, rotate it around like you are screwing it in place, this is my 3rd set to install, struggled on the 1st set, easy to do now. Just a few suggestions117978

Installation was not that hard and it makes a big diffenence in the ride of my vehicle. I have a 10 year old car and the springs were not performing well even though I changed the shocks. These bags are the greatest, especially for the cost.25181

  • Firestone Coil-Rite Air Helper Springs # F4136 for 2011 Toyota Prius
  • According to my contacts at Firestone, the Coil-Rite Air Helper Spring kit you mentioned, part # F4136 will indeed fit the 2011 Toyota Prius. When installing the system, it is crucial that the cuts made in the air line be absolutely square to avoid air leakage. We recommend using a tubing cutter like part # F9009. Keep in mind that the Air Helper springs will not increase the capacity of your vehicle. For installation details, click the provided link.

  • Rear Suspension Enhancement for a 2006 Toyota Prius
  • For the 2006 Toyota Prius we do have one option that will help with a sagging rear end. You can use the SumoSprings, # CSS-1145R. These guys will fit in the spaces between coils on the rear coil springs and take care of the rear end squat. Suspension enhancement is meant to be installed on a vehicle that has suspension that is in good working order. I recommend having the rear suspension checked out first just to be safe. I have linked a video showing a typical installation of SumoSprings yo

  • Is an On-board Air Compressor Needed to Use Firestone Coil-Rite Air Helper Springs
  • You do not have to have an on-board compressor or control unit to use the Firestone Coil-Rite Air Helper Springs # F4136. To add air you would need to use a compressor of some kind. If you happened to have a portable one that would work. Or you could add # WC2050. Otherwise you could use the ones at gas stations. To remove air you would just have to depress the valve, just like letting air out of a tire. I have included a link to the installation details for you. Having the suspension enha
