2004 Ford F-150 - Air Lift SlamAir Air Helper Springs for Lowered Trucks - Rear Axle

  • Air Springs
  • Rear Axle Suspension Enhancement
  • Standard Duty
  • Air Lift

2,000-lb Capacity. Lowered trucks have a weakened load capacity and reduced suspension travel. SlamAir adjustable air springs beef up your suspension, improving ride comfort, preventing bottoming out, and increasing overall safety.


Features:

  • Provides your vehicle with up to 2,000 lbs of suspension support, improving ride comfort, preventing bottoming out and increasing overall safety
    • Designed specifically for lowered trucks
  • Keeps your vehicle level when you are hauling a heavy load
    • Improves steering and brake performance
    • Helps to maintain safe headlight aim
    • Keeps your tires from wearing unevenly
  • Lets you manually adjust air pressure to get the even load distribution and support that you need
    • Level your vehicle front to rear
    • Inflate each spring independently for side-to-side leveling of off-center loads
  • Reduces the strain on your OEM suspension that results from the combination of heavy loads and a lowered truck
  • Diminishes sway and helps to prevent bottoming out
  • Installs between your vehicle's frame and its leaf springs
    • Manual inflation valves are typically mounted on bumper for easy access
  • Includes easy-to-use air line fittings, 2 air springs, mounting brackets, hardware, tubing and manual inflation valves
    • Add a compressor system with in-cab gauges (sold separately) to monitor and automatically adjust air pressure
  • Made in USA


Specs:

  • Load-leveling capacity: up to 2,000 lbs
    • SlamAir springs will not increase your vehicle's weight-carrying capacity. Do not exceed the manufacturer's recommended weight limit.
  • Adjustable air pressure: 5 psi - 100 psi
  • Limited lifetime warranty


So you've lowered your truck, and it looks fantastic. However, you realize that your load capacity and suspension travel have deteriorated in the process. You're bottoming out more, and your ride simply isn't as comfortable as it could be. With SlamAir you can have the great look of a lowered truck while maintaining beefed-up suspension. You get a smooth, safe ride and prevent bottoming out. Now your vehicle will be as strong as it was when you drove it off the dealer's lot.


Enhancing your lowered truck's suspension with SlamAir provides your vehicle with up to 2,000 pounds of load-leveling capacity. SlamAir can accommodate most trucks with a 2- to 6-inch drop, as well as those with flipped axles and notched frames. The air springs themselves are adjustable from 5 to 100 psi, ensuring that you achieve the exact pressure levels that you need for any activity. And the springs can be inflated independently of one another for front-to-rear and side-to-side leveling.


SlamAir comes with manual inflation valves that are typically mounted on the bumper but can be installed anywhere on your vehicle for easy access. For even more convenience and control, you can add a compressor and gauge system (sold separately), which will let you monitor and automatically inflate your air springs.


Air Lift kits are designed to keep your vehicle at normal ride height. You can find the normal ride height of your vehicle by unloading it and measuring the distance between the bottom edge of your wheel well and the center of the hub. After you find and record this distance, you can regulate the amount of air that you put into your air springs to maintain normal ride height - even when you are hauling a heavy load. You will need to adjust the air pressure in your air bags according to the size of your load.


The SlamAir kit includes easy-to-use air line fittings, springs, brackets, air line tubing, inflation valves and all necessary hardware. SlamAir also comes with a limited lifetime warranty with no mileage restrictions.

Works well, great product! Was sold the wrong set on the first purchase. This was the second purchased. I asked for a discounted purchase because it was wring and was able to use the wrung ines in my other truck. Never heard back and the purchase was completed without any discounts.

2014 Ford F-150

Installed these on a lowered 2014 f150 to help when I tow my boat. The directions aren’t very good and the install was a pain as far as mounting the top bracket to the Frame. My frame rails weren’t flat so the top brackets took some work to get them correct. Overall they do what was expected and seem to be ok so far. I’ve only driven for about 50 miles at the moment.

2006 Ford F-150

Worked perfect for my 2006 f150 on a 3/5 drop. Towed a camper with it no problems



by:

Great product works really well



by:

I purchased this setup for my lowered truck so I can continue towing without worrying about bottoming out. Fast shipping and simple installation.



by:

It was very easy to install especially since I already had a C-Notch done in the back with an axle flip. With this added on I no longer band the axle against the bottom of the bed floor.



by:

Great fit. Work perfectly for what I needed. Quick shipment also from etrailer.com

Used it with a mcgaughys c notch, fit f ine.

  • Suspension Enhancement Recommendation for a Lowered 2005 Ford F-150
    We do have a suspension enhancement kit that will work with a lowered 2005 Ford F-150, but it is an Air Lift kit. Take a look at the Air Lift SlamAir springs for lowered trucks, # AL59210. This kit was designed for trucks that have been lowered 2 to 6 inches. Since you are at 2 to 3 inches this kit would be perfect for you. You can fill these air bags up if you have a compressor at home or by using a gas station air compressor or you can add an on-board unit like # AL25592. It will allow...

  • Will the Air Lift SlamAir Springs Raise the Height of a Lowered 2006 Ford F-150
    The Air Lift SlamAir Helper Springs, # AL59210, are not designed to raise the rear of a truck. The purpose of the SlamAir springs is to enhance your existing rear suspension. Air springs are also typically used to reduce the amount of sag when towing or hauling heavy loads. Vehicles that have been lowered typically have weaker suspension and because of that they can bottom out on bumps or with loads in the back of the truck. While these springs will not raise the height of your F-150,...

  • Air Helper Springs for Lowered 2013 Ford F150
    Air Lift does have a Air Helper Spring system that's compatible with your Ford F150, as long as it's not an SVT Raptor model. Their SlamAir kit, part # AL59210 is designed for vehicles that have been lowered between 2 and 6 inches. The Load Lifter 5000 kit you referred to, part # AL88200 isn't compatible with a vehicle that's been lowered. A compressor system is also available, part # AL25592. The system would allow you to adjust the air pressure in your air springs without leaving the vehicle.

  • Suspension Enhancement Recommendation for a Lowered 2008 Ford F-150
    The Air Lift SlamAir system part # AL59210 would be exactly what you would need. This air suspension enhancement system is designed to provide suspension support on vehicles that are lowered between 2 and 6 inches so it would work perfectly on your 2008 Ford F-150 that is lowered.

  • Solutions for Reducing Rear Sag on Lowered 2013 Ford F-150 Towing Trailer
    The Air Lift SlamAir Air Helper Springs # AL59210 that you referenced are designed specifically for lowered trucks and are confirmed to fit your 2013 Ford F-150. The rear sag that you are experiencing is not unusual for a lowered truck, as they will typically have a weakened load capacity because of it. These air springs will definitely do a nice job of reducing that rear sag with their 2,000 pound capacity. With that being said though, I'm not sure how much better a job they will do on...

  • Determining Stock Ride Height to Install Air Lift SlamAir Springs # AL59210 on 2010 Ford F150
    The Air Lift SlamAir Helper Springs you mentioned, part # AL59210 is intended for vehicles that have been lowered 2 to 6 inches, so as a first step you will need to determine how much your truck has been lowered. The Firestone system you mentioned is not designed for lowered vehicles. I do not have any information about the stock ride height, so your Ford dealer would be the best resource for determining how far from stock ride height you are at this point. My Air Lift representative tells...

  • Best Way to Stop Rear End Sag on a Lowered 2014 Ford F-150 STX 4x4 When Towing a Trailer
    The best product to combat sag caused by towing a trailer is weight distribution and not suspension enhancement. If you want to explore the weight distribution option then 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 the weight of anything loaded behind the rear axle of the tow vehicle. But if you decided on suspension enhancement...

  • Recommended Air Helper Springs for a Lowered 2006 Ford F150
    The best option is the Air Lift Slam Air # AL59210 as long as your 2006 Ford F-150 has been lowered between 2-6 inches. These helper springs will improve ride comfort and prevent bottoming out. The Air Lift helper springs # AL59544 you referenced wouldn't work because your axle and frame are closer together.

  • Suspension Enhancement Recommendation for 2014 Ford F-150 with 2 inch Drop
    We have suspension enhancement that is a fit for your 2014 Ford F-150 and is also designed for vehicles that have between a 2 inch and 6 inch drop like what you have, but there aren't any solutions from Timbren for that. Instead you'd want the Air Lift SlamAir kit part # AL59210. This gives you a way to provide additional suspension support that's adjustable.

  • Air Bag & Compressor Kits for Lowered 2008 Ford F-150
    The Air Lift SlamAir Air Helper Spring Kit # AL59210 is a fit for your lowered 2008 F-150 so long as its rear drop is within the range of 2- to 6-inches. Aftermarket wheels and tires will not affect its fit since it installs between your vehicle's frame and its leaf springs .
