Firestone Coil-Rite Air Helper Springs Installation - 2012 Toyota Sienna

Today on our 2012 Toyota Sienna, we'll be installing the Firestone Coil Rite Air Helper Springs, part number F4155. To begin, we'll first go ahead and measure our ride height with the manufacturer's suspension and no weight added to the vehicle. As you can see, to the top of the fender here at the rear, it's 29-3/4 inches. Now, we'll go ahead and add approximately 760 pounds of weight. We'll take a second measurement, and it brings it to 27-1/2 inches. Now, we'll go ahead and run our vehicle over our test course. As we go through the slalom portion of our test course, with the excessive weight in the back, we have decreased steering ability and excessive sway and body roll. As we go over the bumps portion of the course, you can see there's minimal suspension travel distance remaining and causes quite an impact when it encounters the bumps. Now, we'll go ahead and install the Firestone Coil Rite Air Helper Springs.

First, before we install our new air helper springs, we're going to go ahead and take a manufacturer's right height measurement. From the edge of the wheel well to the ground is 39 1/2 inches. Now we'll go ahead and add approximately 1600 pounds of weight to the bed of our pick up, which lowers our ride height to 36 inches. As we go through out slalom course, you notice the body roll from the amount of weight in the bed of the pick up and our steering is less responsive with our ride height and weight distribution being off. Next, we'll go over our bumps course, where you'll notice there's a minimal amount of clearance between the bump stop and the frame. Next, we'll go ahead and repeat the same process with the Firestone Ride Rite Air Helper Springs installed and aired up to approximately 60 psi.

Vehicle Suspension Questions and Answers

  • 2007 Dodge Ram Quad Cab Sags When Towing a Trailer
  • Yes, installing Timbren suspension enhancement springs # TDR1525H4 will prevent the sag at the back of your 2007 Dodge Ram. However it is not the best solution for sag caused by towing a trailer. The best solution for that is weight distribution. Suspension enhancement is best for loads carried in the truck bed. For weight distribution I would need to know the tongue weight of the trailer when loaded and ready to tow plus the weight of anything loaded behind the rear axle of the truck. I have

  • Air Bag Suspension Enhancement for 2014 Toyota Tundra with Curt 5th Wheel Installation Kit
  • The Curt 5th wheel installation kit # C16468-204 includes brackets that install on the outboard side of the frame rails on your 2014 Toyota Tundra. You will need suspension enhancement that does not install in the same place in order for it to be compatible. The Firestone Ride-Rite kit # F2445 installs on the bottoms of the frame rails, see instructions link, so it would be compatible! I have also included a link to the instructions for the Curt installation kit and a video showing install

  • Suspension Enhancement for a 2014 Ram 2500 with Rear Coil Springs
  • Air Lift suspension enhancement kit # AL88289 is not a fit for your 2014 Ram 2500. None of the air bag systems are going to work with the rear coil springs on the Ram. But there is an option. You can install Timbren springs, # TDR2500CA. I have linked a video showing installation of this kit for you, a link to the instructions, and a link to our help article on Timbren springs for you to view. The great thing about Timbren springs is that you do not have to add or remove air all the time, the

  • Will Firestone Ride-Rite Air Helper Springs Interfere With Fifth Wheel On 2014 GMC Sierra 1500 4 X 4
  • The Firestone Ride-Rite Air Helper Springs, part # F2430 is a fit for your 2014 GMC Sierra 1500 4 X 4 truck. The installation on your truck would be the same as you see in the video on the 2011 Silverado. As far as interfering with the installation of the fifth wheel rails, I spoke with my contacts at both Firestone and Reese about the two components. Since manufacturers will not test fit their product with another manufacturer's products they both said that it depends on the other company i

  • Recommended Air Pressure in Firestone # F2250 Ride Rite Air Springs for Towing Fifth Wheel
  • The # F2250 Ride Rite system needs a minimum of 5 and a maximum of 100 psi. The proper air pressure for towing your fifth wheel would depend solely on your personal preference. I'd start at about 50 psi, and make some test runs. Add or lower air pressure until you find which level provides the most comfortable ride. You'll eventually find a comfortable towing and non-towing air pressure.

  • Would Firestone Air Bag Suspension Prevent Trailer Sway
  • I doubt the air bags would do what you're wanting them to do. Their primary purpose is to suspend the weight of anything carried in the bed of the truck. It sounds as if you would be the perfect candidate for an anti-sway bar like part # RM-1139-177. A sway bar would do a much better job of accomplishing what you're looking for. If you can tell me which type of anti-sway system you're using, I might be able to make further recommendations.

  • Will Timbren Springs Fit a 2005 Toyota Tacoma with Modified Rear Suspension
  • Timbren springs # TTORTUN4 are designed for a 2005 Toyota Tacoma with 4 leaf springs on the rear suspension. If you have additional leaf springs then this kit would not fit because it sits between the leaf spring stack and the bump stop bracket. But you mentioned that there is 7 inches of clearance from the frame to the top of the leaf spring stack below. The Timbren kit requires 6-1/4 inches to fit so it does not seem like there would be interference. Make sure that when you took the measure

  • Is Suspension Enhancement Needed for Front and Rear Axles of 2013 GMC Sierra for 5th Wheel Towing
  • You are likely not going to need any suspension enhancement at the front of your 2013 GMC Sierra because the 5th wheel trailer will push down on the bed causing the front to come up a little. The Timbren springs you ordered, # TGMRCK15S, will prevent the sag from being a problem. I would try it first without any suspension enhancement in the front. If you find that you do need something then you can add the front Timbren springs, # TGMFK15CA.

  • Suspension Upgrade for a 2004 Ford F-250 4x4 Short Bed with Curt Custom 5th Wheel Installation Kit
  • Since the Curt custom installation kit for your d2004 Ford F-250 install on the outboard sides of the frame, I recommend a suspension enhancement kit that installs only on the bottoms of the frame. You can use Timbren springs, # TFR250SDE. These springs are not air bags but they do work independently from each other and are ideal for carrying the same or similar loads in the truck like when towing a 5th wheel or gooseneck trailer. I have linked a video showing an installation, the instruct

  • Is Drilling Required to Install Air Lift LoadLifter 5000 # AL57228 on a 2013 Ford F150
  • The only drilling required is to attach the Schrader valves. The Air Lift LoadLifter 5000 air suspension system you mentioned, part # AL57228 is covered by a lifetime warranty, and a 60 day satisfaction guarantee... To avoid leakage, it's crucial that any cuts in the air line be perfectly square. We recommend using a tubing cutter like part # AL10530. There are also compressor systems available, like part # AL25655.

  • Recommendation to Stop 2007 Honda Pilot from Sagging When Towing a Trailer
  • Since the coil spring on your 2007 Honda Pilot has the shock in the middle of it you will not be able to use an air bag kit such as # AL60815 but not to worry, there are other options. The best solution for vehicle sag caused by a trailer is not suspension enhancement but weight distribution. Weight distribution spring bars push and lift to better distribution the tongue weight to all axles of the tow vehicle and trailer and will eliminate that sag.

  • Timbren System or a Weight Distribution System for Towing a 6,000 lb Trailer
  • Adding a Timbren system like the part # TFRTT1502D definitely would help, but it would not be an adequate replacement for your weight distributions system. Your weight distribution system distributes the tongue weight of your trailer to your front axles as well which provides you with a much safer towing setup by improving braking and handling. A Timbren system is mainly designed for vehicles with that are carrying a heavy load in the bed of their truck. For trailering applications a weight d

  • Air Bags for a 2011 Ford F-150 4x4 with Pullrite Superglide 5th Wheel Trailer Hitch Installed
  • First, you are going to want to look at where the installation kit for the 5th wheel hitch installs on the frame of your 2011 Ford F-150. It will be either on the inboard sides of the frame rails or the outboards sides. And in some cases the brackets attached to the frame can wrap around partially on the bottoms of the frame rails. In order for Firestone Ride-Rite kit # F2525 to fit the outboards sides of the frame rails would have to be clear. I have linked the instructions and a video showi

All air suspension systems will not increase the weight carrying capacity of your truck and are designed to be used with trucks that have a good working suspension. For the front of your F-350 I recommend the Firestone Vehicle Suspension, part # F2223. The adjustable air pressure is from 5 psi to 100 psi.

  • Fit of Firestone Coil Rite # F4176 on Canadian-Market 2010 VW Jetta Sportwagen TDI
  • According to my Firestone representative, Firestone makes no fit distinction between US and Canadian Jetta TDI Sportwagen models. I did some online research, and found that the differences between US and Canadian models are the trim levels and some interior appointments, but no differences in the driveline or suspensions. The Firestone Coil-Rite # F4176 would work with your TDI Wagon. You can see the installation details by clicking the provided link.

  • Suspension Enhancement Recommendation for a 2013 Mercedes Benz Sprinter
  • If you have a 3500 2013 Mercedes Benz Sprinter then I would recommend you go with the SumoSprings Custom Helper Springs Kit # SSR-335-47 that you referenced. If you have a 2500 model then you would want the part # SSR-325-47. This product replaces your factory bump stops and upgrades your suspension so that it will sag less, reduce sway and will help support your factory suspension. Timbrens are great, and they work for a lot of people, but we have had complaints that they make the ride ha

  • Will Suspension Helper Springs or Weight Distribution Stop Sag on a 2014 Ram 1500 4x2 Quad Cab
  • As long as your 2014 Dodge Ram 1500 does not have the air suspension then you can use the Timbren springs, # TDR1500DQ, and they can help with the squat when connected to the trailer. But suspension enhancement is not the best solution for sag caused by a trailer because the springs can actually act like a fulcrum and cause too little tongue weight and a poor ride with the trailer. The best solution for rear end sag caused by a trailer is to use weight distribution. You choose weight distribu

The bump stop cup (into which the stock bump stop is fitted at the factory) remains in place on the vehicle frame, according to my contact, after the bump stop itself is removed. The Timbren springs then mount using the included brackets and hardware. Please note that use of an access

  • Suspension Enhancement for Ford F150 2WD with PullRite SuperGlide Rails

Those PullRite brackets you have on your trailer frame are pretty huge and would prevent a Firestone Ride-Rite Helper Spring # F2542 from being installed because they both attach to the frame at the same point and would interfere with each other.

The distance from the outside of the truck frame to the inside of the tire must be at least 8 inches for this kit to fit.
