Why Choose Strutmasters Instead Of Those Other Guys
The assorted parts that make up the original air suspension system in the 03-06 Ford Expedition must always function in sync or the suspension system may cease working. As The Suspension Experts, we know just how expensive it can be to bring your Expedition to the Ford dealership service center each time it needs a suspension repair. Our unique air to non-air suspension conversion kit is an affordable and high-quality solution to this all-too-common dilemma. This kit, manufactured in America, includes four completely pre-assembled coilover struts plus our bundle kit: two lower ball joints, inner and outer tie rod ends, and sway bar endlinks. The kit is a direct replacement, meaning no modifications are needed before it is installed on the Expedition. We stand behind our products with the Strutmasters Limited Lifetime Warranty. The kit can be installed in as little as one hour per wheel, while the suspension warning light turns off after about thirty minutes. Those who like to work on their vehicles themselves appreciate the detailed installation instructions that come with the kit, as well as the installation videos available for viewing online. Customers can always take advantage of the wisdom of our ASE certified technicians who are happy to answer any questions about an Expeditions failed air suspension system.
How Do I know If My Expedition Air Suspension is failing?
Early diagnosis of a failed or leaking air suspension system on the 03-06 Ford Expedition is critical to avoiding suspension total failure. Look for these common signs of a bad suspension before other major components begin to wear out. The most noticeable is an uneven height difference between different sides of the Expedition. Typically there is a sagging rear or front end while the opposite side remains inflated. Often this gives the illusion the Expedition is squatting down too low to the ground. Sometimes there is leaning from one side to the other. In either case, if the Expedition has any problem reaching and maintaining its proper ride height, a failing air suspension system is likely to blame. One obvious red flag indicator of a bad suspension is an illuminated suspension warning light on the instrument cluster. Issues with the air compressor can also point to a suspension issue. If the compressor has stopped working or is running too often, the suspension system likely needs repair. Any of these symptoms should be fixed promptly.

Suspension Components List
The 2003-2006 Ford Expedition is built with the following suspension components:
2003-2006 Ford Expedition Air Springs (x4)- commonly referred to as air bags, a plastic and rubber bag that is fitted on top of the strut that uses pressurized air as a cushion instead of a metal coil spring to hold a vehicle off of the ground and off of its wheels. These are the number one cause of all air suspension leaks. All air springs all go bad at about the same rate. If one is leaking, the others will not be far behind. For a proper repair, all of them need to be replaced at the same time.
2003-2006 Ford Expedition Struts (x4)- a type of shock absorber; has metal tubing filled with gas-charged hydraulic fluid that is connected to the wheel of a vehicle in order to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle.; the air spring assembled on top of the strut is commonly referred to as an air strut.
2003-2006 Ford Expedition Height Sensors (x4)- a linkage located near each wheel of a vehicle with any electronic suspension that, either mechanically or electronically, constantly measures the height of the vehicle, and reports this information back to the control module so that the computer can identify if changes in height need to be adjusted accordingly. The ride height sensor is a moving part, and like all moving parts, they will eventually wear out.
2003-2006 Ford Expedition Air Lines- tubes that run from a compressor (air suspension) to the air struts which carry pressurized air to the air bags components in order to adjust the height of the vehicle, respectively.
2003-2006 Ford Expedition Solenoids (x4)- usually L-shaped, these plastic components connect the electrical connection and lines of suspension components to the suspension control module on vehicles with active suspension. The solenoid regulates the air pressure for each air spring. Solenoids start to leak as they wear out causing the vehicle to sag or to lean. This will cause the ride height sensor to send a signal to activate the compressor in an attempt to inflate the air suspension and level out the vehicle. This excessive work load will eventually lead to total failure of the compressor.
2003-2006 Ford Expedition Compressor- creates/sends pressurized to active suspension components. When the air suspension starts leaking, the compressor/pump starts working harder to try to keep the system inflated. By the time air suspension leaks down completely, sitting the vehicle on its tires, the compressor will either have failed or be well on its way to full failure. Buying replacement struts and taking the time to install them only to find out the compressor still needs to be replaced can be very frustrating, time-consuming, and expensive.
2003-2006 Ford Expedition Dryer Assembly- used to keep moisture out of air lines and air springs in order to prevent freezing and internal cracking of these parts. Once air suspension starts leaking, moisture will build-up throughout the air system. Moisture damages the air suspension from the inside. The dryer will need to be replaced in order to eliminate the moisture and prevent any further damage.
2003-2006 Ford Expedition Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicleâs correct ride height.
2003-2006 Ford Expedition O-rings- Although they are the least expensive parts of the air suspension, they are responsible for maintaining the seal where all of the air lines connect. Be sure to replace the O-rings when repairing any air suspension system.
2003-2006 Ford Expedition Lower Ball Joints (x2)- bearings that connect control arms to the steering knuckles.
2003-2006 Ford Expedition Inner and Outer Tie Rod Ends- endlinks for the first and last stage of the steering process.
2003-2006 Ford Expedition Sway Bar Endlinks- these connect the sway bar to the vehicle in order to redistribute the vehicleâs weight while cornering.

“Thank You Chip, it does not surprise me in the least that Strutmasters has become so successful, your customer care and service is like no other that I have ever experienced! In an age were customer service is handled through automated phone recordings, every time I have placed a call to your business I have always received a live voice, and a knowledgeable and friendly voice at that.
A true rarity these days, please keep up the excellent work. As far as I am concerned, you have a customer for life.
Thank you sincerely,
MUCH better than the OEM air ride. THANKS!
“Man ‘oh’ Man…this is the best thing that happened to my truck since i bought it..I’m writing to you from Dar Es Salaam, Tanzania (EAST AFRICA), I’m a proud owner of a Lincoln Navigator, but the air suspension have eluded my pride for sometime not to mention it killed my compressor too..Now, with the ez replacement, Im rolling high and comfy with Strutmaster Non Air Conversion..Yap, it feels like new again and you know, we’re talking about African roads sir; Ford should put your products from the get-go..Thank you for making me proud again.
Asante Strutmaster, Asante sana!! Thank you..”
“The installation went fine. The shop Christian Brothers in Irving, TX was very impressed with the quality of the parts and the ease of replacement. I was told that a catalog was included in the shipment. They kept it so they could offer the same kind of replacement parts to other customers. My wife enjoys her Navigator again. You have a great product. It’s a great value.
i had a hard time installing these conversion kit. it was not that eazy to install but ill take it to the shop and see what happens. also it was much harder than what the video says. ill update my comment after the shop.
Couple of months ago had the 4wd suspension kit installed by Muffler Masters and they did an excellent job. The “new ride” is equal to or better than the original “air” on my 2004 Navigator which I had bought new. The front end has less roll in curves and cornering. Frankly, I’m very surprised at the results with this aftermarket unit. But it really is as good as advertised. The car has the same stance and height as original. I wasn’t going to fix the original. Could just see an endless hole with the likelyhood of continued replacement of parts over time. But with Strutmasters when its installed, its done! And you don’t have to worry about more problems…just worry about the cost of gas to run this “beast”. Get one. You won’t regret it. Larry Shive
Just installed the kit on my 2004 Navigator on Friday August 18, 2012. The ride is comperable, its not an air suspension however, it rides as smooth and handles great. I have test driven the new 2012 Navs with out the air suspension and hate the ride but am happy to say I still love the ride with this conversion. I love the way the truck sits up higher now and am looking forward to the first year in a long while when I can go to the mountains in the winter and not have the suspension lay down on me. I have the kneal down system on my Nav, I was not able to get the air fault to not come on so I just turned it off in the back and press reset when I get in every time. It is a small price to pay for no longer having to worry about that suspension. I highly recommend it… I did not try taking it to the dealer to have them reprogram the kneal down. I figured I would save the money and just press reset. If any one has gone that route and had success let me know I might swing for it…
