Why Choose Strutmasters Instead Of Those Other Guys

Strutmasters knows the wide array of parts that construct the 2003-2006 Ford Expedition air suspension system. Our conversion kit eliminates having to depend on all those parts functioning properly and in sync. The kit is a direct replacement for your faulty suspension and includes four completely pre-assembled coil-over struts that are installed with five bolts per strut. Our suspension conversions are more affordable than the original parts from the dealer, and the parts in the kit are so high quality we back them with our lifetime limited warranty. Your Expedition will be fixed in no time- the kit is installed in about one hour per wheel, and it only takes about thirty minutes for the suspension warning light on the instrument panel to turn off. Your repair is sure to go smoothly with the support of our helpful and informative pictorial instructions. Our YouTube channel is available for you to view videos of us performing real installations. And lastly, our in-house experts are available to answer any questions you may have about your bad suspension.

How Do I know If My Expedition Air Suspension is failing?

There are common signs that the air suspension is leaking or failed on your 2003-2006 Ford Expedition 4 Wheel. The most obvious is a sudden noticeable uneven height difference between different sides of the Expedition. You might notice sagging from the rear to the front end, or perhaps leaning from side to side. One side may look more inflated than the other. Maybe the entire vehicle seems to be squatting down too low to the ground. Overall, your Expedition ride height should be consistent and appropriate according to Ford standards; otherwise, you may be dealing with a bad suspension. Other signs include a suspension warning light or message in the instrument panel. Oftentimes, the air compressor ceases working, or maybe is running way too often (will be noisy). In all of these cases, a repair or replacement may be necessary before other major components on your Expedition wear out.

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 vehicle’s 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.

“Very good service from the representative that I spoke with on the phone. Parts arrived in a couple of days, very nice service for ground delivery. The only problem, is one of the boxes arrived open, hopefully nothing fell out thanks. Parts going on this weekend. Thanks”

“Dear Web Master,

I really appreciated the help I obtained from your technician, Lou. He fully explained the product and assured me that I would have no trouble finding a mechanic to make the install. The repair quote for replacement of the air suspension system on my Nav was over $3000 from Tires Plus, and finding your company and the conversion kit is a godsend. Thanks!

I’m satisfied they fit perfect. Thanks your product is the best.

I used the conversion kit for my Ford 2003 Expedition, and it was easy and only took me and a buddy about 2.5 hours to do all four wheels. The ride is as good as the air suspension, and i dont have to worry about any more broken bags. the cost of doing all four wheels is less than doing 2 of the air bags, and I had already replced the compressor once. The height of the vehicle is approx1-2 inches higher than the air suspension, but i like the higher look. Thanks strutmaster- well worth the money.

“I got the Strutmasters Conversion kit and I am Extremely Happy with the results. Its only been 3 days of having them on, but the anxiety of wondering when and how your vehicle is going to drop was unbearable and StrutMasters has relieved that anxiety.

I did a lot of research on the Air Suspension problems with my Navigator. Ford kept wanting me to come in for a $150.00 diagnosis, saying it would probably only be a $300 – $500 part replacement to preserve my wonderful air ride, and that I wouldn’t be happy with a conversion. No Way, No How.

Just Read on the internet, people spending $1000’s each year to get something replaced on their Air Suspension. Once it starts to go you will be forever troubleshooting the problem.

I only had the Air Suspension problem for 3 weeks, I could not let my family’s life’s be at risk any longer.

Do yourself a favor and get the Conversion kit, Not a Penny wasted.

Thanks SturtMasters.”

“Let me tell you my family felt like we had bought the car all over again. The excitement of driving and riding in the car with a smooth ride again was awesome, to say the least. I am so glad we did this. Will be back with you again soon.

“Both Livernois Vehicle Development and Ford Motor Company want to thank you for the time you spent in helping develop a crucial spring that was required for the Navigator Boom Vehicle that is currently in development.

Your contribution was a major factor in the success of this project. Your time and dedication are very much appreciated.

Thanks they worked out great

I installed conversion kit on 2004 Eddie Bauer Expedition with 100,000 miles. Front end conversion was good. After conversion rear end is low and has soft “springy” ride. I tried to get help from Strutmasters to fix the problem but they said the height was in the correct range even though the rear sat lower than the front. The more we drive the vehicle the softer the rear suspension gets. I’m now trying to decide how to fix the problem as the expedition now handles poorly on corners and when you hit any bumps. I would not recommend this product.

We had installed the Navigator Conversion Kit with no problem and returned the car back to our customer yesterday.

Name: | Location: Sterling, VA United States | SKU: FX24F

“My 16 year old Grandson putting in your struts and springs. Before and after. Thanks a lot.

So easy, a 16 year old can do it.

Strutmasters is the bomb! We saved about $4300.00 and it was fun too! Don’t get any ideas, I am going to culinary school.”

Name: | Location: Greenville, SC United States | SKU: FX24F

Just wanted to say thank you thank you thank you for the struts for my 2004 expedition. My friend that put them on said it was simple n now I dont have to worry about leaky air bags. Its a little higher n I love it.

Name: | Location: Edwards, MO | SKU: FX24F

“Everything went great! It was one of the easier upgrades I have done on a car. The parts fit perfect without any modifications. My next door neighbor assisted me and he was amazed how easy the upgrade went. It took about 45 minutes a strut which includes taking the wheels off and on. Very pleased with the ride and the look of the navigator now that it is not sitting flat on the frame.

Thanks for professionalism of your company, the excellent product and the followup.

Just Installed a full set of replacements for my 03 Navigator. Very pleased!!!! Is it as smooth as the air ride, no. But it sure is a lot cheaper in the long run and not a bad ride at all! I have took Pictures from before, during and after. feel free to email me for em. [email protected]

Name: | Location: Katy, TX United States | SKU: FX24F

I am pleased with my new suspension system. I wish I knew about it earlier, I would have saved lots of money, time and frustration. The only complaint I have is that the suspension light continues to come on. We need a solution!

Name: | Location: Houston, TX United States | SKU: FX24F

“Thanks Strutmasters! Great product! Easy install! I think the only thing that can be improved on this otherwise perfect product is if there was a way to list the size sockets will be needed for the
install. But not a big deal at all. And I love Strutmasters. I will be referring people! ”

I could not be happier with the conversion kit I purchased for my expedition. I love the SUV but of course the only drawback was the factory air ride system. Purchasing and installing your product was cheaper than having Ford fix even one component of the system. The ride is just as good and my truck handles great! My local mechanic even wants to start selling your product!

Name: | Location: TX United States | SKU: FX24F

Good product. Easy install. Took about 5 hours. I would recommend this product to eliminate the air ride.

Name: | Location: Norfolk, VA United States | SKU: FX24F

I know everyone is entitled to their own opinion but sometimes they your keep lies to themselves. The first review that talks about the ride is not great and these struts are not worth it is a complete lie. I just installed my struts on my 04 Lincoln Nav and I swear it is the best thing I have done to my SUV. The ride feels just like the air ride suspension and I put that on my life. I am so impressed with how my truck rides, it feels like I just bought the truck off the showroom floor. Was not hard at all, all you need are the right tools and a little muscle and you will have no problem getting it done. I would say if you can change oil you can change your struts, Strutmasters you truly are masters of strut and I salute you!!!!!

“Good morning,

We received the conversion kit a few days ago. We had the work done the day they arrived, so I was unable to take pictures. Everything went well and we are surprised how quick and easy they are
to change out.

Thanks,

I am very satisfied. Now that the conversion is in place, I realize how many problems the faulty air suspension system was causing to the whole vehicle. Thanks, Tom

My overall experience from conversations on the phone with the techs, to the instructions provided were great and I would not change anything.

Recently ordered the conversion kit for the air ride suspension on my Expedition to convert to coil springs and shocks. The parts were shipped the next day and arrived as promised. Had the work done by the team at Tuffy’s and everything is working as it should. Thank you Strutmasters.

Name: | Location: Uniontown, OH United States | SKU: FX24F

Did the install in one easy day by myself in my garage. No air tools, only tool I had to go get was a large metric socket (30mm) I think. Way easier then the install I did on my Mark VIII!! And the ride seems about the same, just got back from a 1200 mile trip and it road fine, even through the WV turnpike at 75 mph. I’m currently looking for another Nav with air ride issues to buy cheap and do an install on. Love this car.

Name: | Location: | SKU: FX24F

The shop that I took the kit to were blown away with the ease of design and engineering. They had never heard of your company and said they would contact you to be a dealer. Here in Michigan we have some of the worst roads in the country. Thanks for a great product. My Expedition loves you guys.

Name: | Location: Denver, CO United States | SKU: FX24F

“Just had my air suspension replaced with the “”2003-2006 Lincoln Navigator 4-Wheel Air Suspension Conversion Kit (2WD & 4WD)”” I am so relieved, the ride is great, and the quality of the struts were great (according to my mechanic and from what I saw)! Delivery took about a week and the tech service, and Dustin & Vito were more that helpful!
Living in the Denver area, every time the temp would drop below 20 degrees so would the front end … when it did it while I was on the interstate at 65 mph it got my attention … started to get the “”bring it back in if it does it again”” story from the dealership … what a pain — Thanks Dustin, I am very happy with my new “”ride”” :0)

Name: | Location: SAN CLEMENTE, CA United States | SKU: FX24F

I installed the kit in less than three hours, and it was pretty easy to say the least. Everything lined up nice without any modifications or the use of a hammer.

Name: | Location: Evington, VA United States | SKU: FX24F

My air shocks went out on my 2004 Ford Expedition. I ordered the conversion kit, it came quick, in tact, and for a good price.

Name: | Location: Houston, TX United States | SKU: FX24F

I have had four suspension problem betwen two navigators. All cost over 1,500. This last one (busted airbag) the truck was out of warranty. Thank God I found Strutmaster. I wasnt sure how easy it would be to install. IT WAS A BREEZE! At first I went to rent an impact wrench and air compressor from my local hardware store but I took it back. All I need was my sockets (15mm,19mm,29mm,30mm) a few wrenches and a rented breaker bar. I save alot of money on parts and on labor. Now Im trying to see if i can contract with a local repair shop to make some money doing these repairs for customers! If your truck is still in warranty take it to the dealer and make them pay to fix this BS. But if it is not STRUTMASTERS is the truth! the only way to roll. P.S. I love the red color hehehe

Name: | Location: Rochester, NY United States | SKU: FX24F

Everything worked out great, those things went in very easily, I did it right in my driveway. I would definitely recommend these to somebody else, thanks
