Expert Answers about Firestone

  • Recommended Air Pressure of Firestone Ride Rite Air Springs # F2071 on Dodge Ram 3500 Dually
  • Other than saying that the air bags need to be kept between 5 and 100 psi, Firestone does not offer much in the way of specifics. The instructions mention that as a general rule of thumb, 1 psi will support approximately 40 lbs of load. Your best bet is to use enough pressure to level the vehicle, and then adjust plus or minus according to your personal preference. You can do this with the 5th wheel in place, and for the unloaded scenario. Keep in mind that using an air bag suspension...

  • How To Tell What Size Firestone Lift Spacers Are Needed On A Truck With A 6 Inch Lift Kit
  • To determine what size lift spacer to use on your vehicle with Firestone Ride-Rite Air Springs, measure the distance between the upper and lower brackets of your air helper spring kit, and whether the kit mounts on the leaf spring or the axle. The spacer needs to be the same length as the amount of lift applied to the axle on which the air helper spring is installed. The axle mount kit would have the lower bracket mounted to the axle. The leaf mount kit would have the lower bracket mounted...

  • How to Remove the Air Hose for the Firestone Sport-Rite Air Helper Springs
  • I made a short video for you showing you how to remove the air hose from the air line fittings on your Sport-Rite air helper springs. The main thing to remember is to have the collar on the fitting pushed down when removing the air hose. It may take a little elbow grease to remove, but it should release if the collar is held down.

  • Diameter, Maximum and Minimum Height for Air Bags in Firestone Ride-Rite System # F2071
  • I went out to the warehouse and pulled a Firestone Ride-Rite system # F2071. When fully collapsed and no air in the system it measures 2-3/4 inches not counting the valves on the top. Please note that you should always have at least 5 psi in the springs up to 100 psi. When in its regular state the bags will not expand much beyond how they come in the box. They are 6 inches tall again not counting the valves. And finally, the diameter is 5-3/4 inches. Use these measurements as guides...

  • Firestone Air Bag Suspension Enhancement for a 2014 Chevy Silverado LTZ Z71
  • The axle your version of the 2014 Chevy Silverado would be the Z71 rear axle and that should also be a 4 wheel drive model. The proper kit for a 1500 would be # F2430 that you have referenced. But if it happens to be a 2500 or 3500 then you would need to use # F2596. Also, if you do not want to manually fill the air bags every time you can install a Level Command II kit, # F2219, which will allow you to fill/remove air from the bags from the cab of the truck. I have also linked some...

  • Replacement Upper and Lower Mounting Brackets for Firestone # F2299 Ride-Rite Air Spring Kit
  • It sounds like what you're needing is the Firestone Replacement Bracket Kit for the # F2299 Ride-Rite Air Helper Springs. The part number for the bracket kit is part # F2479. This will provide 2 upper brackets, two lower brackets, two upper braces and the necessary hardware. Firestone offers the brackets individually, upper bracket # F5757 and braces # F5758, but hardware isn't something they sell separately. Your best bet would be to get the entire kit. Keep in mind that this bracket...

  • How to Reduce Sag on a 2012 Ford F-250 Super Duty with Towing a 5th Wheel Trailer
  • The best way to reduce the sag on your 2012 Ford F-250 when towing your fifth wheel trailer is to add a rear suspension enhancement system. The two most common types of rear suspension enhancement systems are air bag systems and rubber spring systems. The rubber spring systems like the SumoSprings and the Timbren Springs, # TFR250SDG, are typically more economical than an air bag kit like the Firestone Ride-Rite Air Springs, # F2550. The Timbren springs and the Ride-Rite kit that I mentioned...

  • Can Firestone Air Bags be Used with Weight Distribution Hitch when Towing a Trailer
  • You could use air bags and weight distribution at the same time. But if you are experiencing rear end sag on the tow vehicle caused by towing a trailer then the best solution is weight distribution. But not just any weight distribution system. It has to be the proper capacity. To choose a weight distribution system you will need to go by the total tongue weight of the set up. This is calculated by taking the tongue weight of the trailer, when loaded and ready to tow, and adding to that...

  • Availability of 6 Inch Spacers for Firestone Airbags on a Truck with 6 Inch Lift
  • You would just need the 6 inch spacers, # F2374. Using 2 sets of the 3 inch spacers is not a good idea because the more components you add to the system the more points of weakness there are. Not that the spacers or system are weak but if you can avoid a potential issue it would be a good idea. Spacer # F2374 is for use on air bag systems that mount on leaf springs and # F2375 is for air bag systems that mount on axles.

  • Air Lift or Helper Spring Recommendation for a 2000 Ford F-250 Super Duty Towing a Camper Trailer
  • The product that will work best for you will depend on how you will be using your truck and why you are looking for a suspension enhancement system. If you are looking to level your truck because you do a lot of hauling with varying load weights and tow the trailer occasionally then the air bags would work well. I would recommend using the Air Lift LoadLifter air springs, # AL57298, for 2 wheel drive or, # AL57390 for 4 wheel drive models of the 2000 F250. I recommend these air bags...

  • Best Firestone and Air Lift Air Bag Kits for a 2016 Sierra 2500 HD 4x4
  • The top of the line Firestone Ride-Rite Red Label Extreme Duty Air Helper Springs # F2702 would be an excellent option for your 2016 Sierra. Firestone is a time tested brand that stands behind its industry leading air bags with a limited lifetime guarantee. However, I would go with the Air Lift LoadLifter # AL88396 because it is more cost effective and has Internal Jounce Bumpers that set it apart from Firestone. These Internal Jounce Bumpers act as a back up if the air bags were ever...

  • Air Bag Helper Springs for a 2017 Chevy Silverado 2500 4x4
  • For your 2017 Chevy Silverado 2500 4x4 I do recommend the Firestone Ride-Rite helper springs # F2596. I have included a link to a video showing an example installation of this kit for you. Adding an on-board compressor system is an excellent idea any time air bags are used on a vehicle. It will allow you to add or remove air from the comfort of the truck cab so you will not have to have a separate compressor. There are different compressor systems you can use. If you are looking...

  • Improving Ride Quality On a 2012 Chevy Express Van 3500
  • Full size vans, especially heavy duty models like your 3500, are going to ride a little rough when not loaded because of the size of the vehicle and the travel of the suspension (not being compressed by weight means a lot of possible movement). Think of it like riding at the back of a school bus. The good news is there are some things you can do to get a better ride. Suspension enhancement will help. Air bags will help but # F2173 that you referenced is intended for vehicles with dual...

  • 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...

  • Troubleshooting Leakages On Firestone Ride-Rite Air Helper Shocks on Ford F-150
  • For your Firestone Ride-Rite Air Helper Springs, you can check the fittings for air leaks with an applied solution of soap and water. If a leak is detected, deflate the air spring by depressing the valve core. The tubing can easily be removed from the fittings by pushing the collar on the fitting towards the body of the fitting while pulling out the tube. Next, check the tubing connection to ensure that the air tubing is cut as square as possible and that it is pushed completely into...

  • Will the Firestone Ride-Rite Air Bags # F2525 Fit on a 2013 Ford F-150 With Reese 5th Wheel Hitch
  • I do have a rear suspension enhancement option for your 2013 Ford F-150, however, the Firestone Ride-Rite Air Helper Springs, # F2525, are not compatible with most fifth wheel frame brackets that mount to the outboard side of the vehicles frame rail. Most fifth wheel brackets block the frame and it is not recommended to install the Ride-Rite kits on top of fifth wheel brackets. If you have a fifth wheel kit that uses the 4 individual universal L-brackets, then the Ride-Rite kit may...

  • How Much Air Pressure Should be Run in Firestone Ride Rite Kits
  • With Firestone Ride Rite kits like the part # F2071 the absolute minimum psi you will need to run is 5 psi. This prevents the bags from getting damaged. Typically people run the amount of pressure that allows the vehicle to sit as level as possible when loaded. Going with more pressure will cause the ride quality to be harsh and bouncy. Too little and the suspension may still sag. Trial and error is the best way to find the perfect amount. I attached a help article on Firestone air...

  • Gooseneck Hitch Compatible with Firestone Ride Rite Suspension for 2001 Dodge Ram 3500 4X4 Dually
  • According to Firestone, both the Ride Rite Air Spring Kits compatible with your truck, part # F2264 and # F2071 would indeed prevent you from installing a fifth wheel or gooseneck hitch. Both air spring assemblies install on the outboard side of the side of the truck frame, as would the frame mounting brackets for a gooseneck or fifth wheel hitch. Your best bet would be to replace your existing air bags with a solution that mounts to the bottom of the frame members, replacing the factory...

  • Can Firestone Sport-Rite F2337 Install on 2013 Chevy Express Van with 3 inch Lift
  • What you can do is use lift spacers with the Sport Rite kit part # F2337 that you referenced which is a fit for your 2013 Chevy Express van. Since you would need a 3 inch spacer the part you'd need is the # F2368.

  • Helper Springs for a 2014 Chevy Silverado 1500 Z71 LT
  • For the type of loads that you are carrying in your 2014 Chevy Silverado 1500 Z71 I recommend Timbren helper springs # TGMRCK15S. There is no maintenance required with these springs and they will prevent that rear end sag you are experiencing. And they have a limited lifetime warranty. Several of the guys here use these springs and they love them because they are so easy to use. Just install them and you are done. No need to worry about adding or removing air or possible leaks in air...

  • Suspension Enhancement To Reduce Porpoising When Towing 30 Ft Travel Trailer w/ 2015 GMC 1500
  • Of the various suspension enhancement products we offer, the TorkLift StableLoad Rear Suspension Upgrade Kit # TLA7310 is designed to preload the factory overload springs in order to combat porpoising and reduce side to side sway and body roll. The wedge pack is hinged, which allows you to swing the wedges out of the way when you're not towing or hauling. No drilling is required for installation. I believe this option would be more effective than an air helper spring system.

  • Rear Air Bags Recommendation for a 2003 Ford F-250 Super Duty 2WD
  • For your 2003 Ford F-250 Super Duty 2WD, I would recommend installing the Firestone Ride-Rite Air Helper Springs, # F2550. There is not much of a difference between the Ride-Rite Kits, # F2550, that I recommended and # F2484 that you referenced, but the brackets that are included with the # F2550 springs are compatible with fifth wheel and gooseneck trailer hitches. It may not seem that important now if you do not have a gooseneck or fifth wheel hitch, but the # F2550 air springs will...

  • Air Pressure Range for Firestone Ride-Rite Air Bags
  • I spoke with my contact at Firestone and the air pressure range for the vast majority of all their Ride-Rite air bags is 5 psi to 100 psi. The 21-9015 number that you mention is actually the order number for the "equipped with Ride Rite Helper Springs" sticker and is not the part number for the air bags. If you would like to send me an email with the year, make, and model of your vehicle, I would be happy to help locate an instruction manual for you. I have attached an article that...

  • What are the Measurements of the Air Bag in Firestone Ride-Rite Kit # F2445
  • If your 1974 Toyota Class C RV is built on the 1974 Toyota pickup chassis then we do have options for it, see link. I went out to the warehouse and pulled Firestone kit # F2445 to measure the air bag. When compressed the height to the top of the spring is 2-5/8 inches and to the top of the valve it is 4-3/4 inches. When not compressed it is 6-1/8 inches tall to the top of the spring and 7-5/8 inches tall to the top of the valve. The overall diameter is 6 inches whether compressed or not.

According to the techs at Firestone the most similar compressor available is the Firestone Heavy Duty Air Compressor # F9285. This would be the best possible solution I could recommend for you for a replacement.

  • Rear Helper Springs for a 2016 Ram 2500HD 4x4 Towing a Travel Trailer
  • We do have some rear helper springs for your 2016 Ram 2500HD 4x4 that do not require adding air. The most popular option for your truck are the Timbren springs # TDR2500D. These springs have an 8,600 pound capacity (but do not increase the capacity of the truck bed) so they will work well to keep the truck level and provide a better ride. I have included a link to our informational article on Timbren springs for you.

  • Removing Bump Stop on 2014 GMC Sierra z71 to Install Firestone Air Bags
  • The jounce bumper cup where the OEM bumper sits stays on the frame of the 2014 GMC Sierra 1500 when installing Firestone air bags # F2430. Just the rubber bumper gets removed. Many times, if these bumpers are not held just by compression, there is a bolt that goes through the middle of it and is accessible through a hole at the bottom of the bumper. There may also be a nut on top of the frame. Take a look at the video I have linked that might also help.

  • What T-Valve and Inflation Valve is Needed for Firestone Ride-Rite Air Helper Springs
  • You would use a tee, # F3025-1, if you wanted to be able to fill both bags at the same time. However, if you carry many different sized loads it would be more beneficial to keep them separate because depending on the load, one side might need more air than the other. Inflation valve, # F3032-1, is what is used in the kit # F2403, so you would not have to get a different valve. Most portable air compressors are not all that great at filling something like air bags, especially when under...
