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.

“So far so good ! Had Firestone install the set about 3 weeks ago. This weekend we’ll take our 3rd 600 mile road trip through the hills of Arkansas without worrying about the suspension.

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!!!!!

Mahalo to the entire Strutmaster family for making quality kits at a great price and proper fit always.

“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.”

As the subject states however I was pleasantly surprised. The truck sits about 2″ higher which I think is normal. I believe it was riding too low to begin with do to all the issues I was having with the air ride. I am very happy with the handling and ride quality. I did the install myself and if you plan to do so make note: besides a good standard socket set including 15mm, 19mm, you will need a 30mm socket and wrench to get the coil bolt off. Also a good floor jack to raise this heavy truck and two heavy duty jack stands. A impact gun would be a big help for you as well to get the bolts off. I did the back two first then did the front two. The back went it super easy, the front I had to get the floor jack under the coil and jack it up just a tad to line up bolt hole but it was not a big deal otherwise. I am glad I took this route no more worrying about a bottomed out truck especially when I am up North somewhere towing my enclosed trailer with a bunch of ATV’s in the back.

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. markagarcia@msn.com.

My husband is unemployed and broke, he was a very happy man when he finish the job. Save us thousand of dollars and he is now worry free from air air suspension going bad. Thank you strutmaster

Name: | Location: Bakersfield, CA United States | SKU: FX24F

Yesterday UPS arrived around 10:00 with my new Navigator suspension. I have spent over $6,000 with the local Lincoln dealership in the past 5 years fixing the suspension issues. I delivered the car and the new Strutmasters system to my mechanic. At 4:00 he called me to say I no longer had a “Lowrider”. He charged me $226.00 to do the install and so problem solved PERMANENTLY for less than $1,000.00. Car rides better than ever and my wife is thrilled. THANK YOU STRUTMASTERS! Your postcard is one piece of “junkmail” I am glad I looked at.

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.

“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!


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

I purchased the 4 wheel air suspension conversion to coil kit. First off, it’s a much bumpier and louder ride. I could feel every single small bump, even the lines that make up the lanes. All these people who wrote it rides the same or it rides just like their air suspension did are crazy. My expedition on springs rides much smoother and handles better than these kits on my Navigator. I’m going to sell this kit and buy air suspension again. It’s a good cheap option, but if you can afford it replace with air suspension. I had mine professionally installed at Lincoln/Ford dealership. All other components in great working condition on my vehicle.

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.

I have always wanted a LINCOLN NAVIGATOR and this year i finally was able to get one. A 2003 with low mileage and a price to good to be true. Made the purchase no problems, after driving for about a month it happened the whole truck leaned to one side then the front end dropped and would not raise back up. I said to myself thats why i got the truck so cheap!!! But i did my research and found the best company in world STRUTMASTERS.COM. Bought the conversion kit and installed yesterday and I’m driving BABY I’M DRIVING. Thank you so much and GOD BLESS.

“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! ”

Strutmasters was my best find ever. I own a 2003 Lincoln Navigator, Great SUV, But the air ride is a problem we bought this suv in 2005 still had warranty left and we bought a extended warranty till 75000 miles in that time the air compressor went out 3 times, 2 times under warranty, this last time at 95000 ford wanted 499.00 plus labor for something that last about 18 months, then i found strutmaster there site and there sales staff, are very helpful even when i was installing them, i call my Sales man Anglo with one very simple problem, i felt stupid but Anglo was very helpful and walk me right through it, This SUV is my wife’s dream car She is so happy with ride and no more waiting for the air ride to air up, are those terrible rides home with no air. we are planing on keeping for many many years. I took Anglo advise and put them on e-bay and sold them used, also advised many buyers to you site, that could not buy them from me used, Thank You Again Strutmaster. a customer forever.

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

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!

Thanks to you for your product and staff. I just completed installing the 4 coil-over strut conversions on my 2003 Navigator. Purchase was a breeze with you friendly folks on the other end. Installation was as easy as advertised and the ride is very comfortable. No more worrying about leaky airbags, long-running compressor, etc. Thanks again for developing such a good product and making it easy for a shade-tree guy like me to install.

“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.

I purchased the Strutmasters conversion package for my 2003 navigator and experience a wonderful ride. Prior to the conversion I was in complete dismay, the front airbags slowly leaked, I was riding low, leaning, bumpy, and probably dangerous. Now I am experiencing a wonderful, wonderful ride. At this point I have only praise for the quality of items I received with Strutmasters. Wonderful, wonderful product, wonderful customer service, everybody was wonderful with me.
