How Do I know If My Navigator Air Suspension is failing?
There are common signs of a failed and/or leaking air suspension in your 2003-2006 Lincoln Navigator. The most noticeable is a sudden uneven height difference between different sides of the Navigator. This may look like sagging, perhaps from front to back, or leaning, from one inflated side to the other. Sometimes, the entire Navigator looks like it’s squatting down lower than usual. If your Navigator is no longer reaching and maintaining its appropriate ride height, it might have a bad suspension. Other signs to look for include: a suspension warning light or message on the instrument panel, or a non working air compressor (not working at all, or too noisy and overworked). You will want to repair your suspension ASAP before other components on the Navigator wear out. Worst case scenario- you may need a replacement if you have suspension total failure.

Suspension Components List
The 2003-2006 Lincoln Navigator is built with the following suspension components:
2003-2006 Lincoln Navigator 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 Lincoln Navigator 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 Lincoln Navigator 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 Lincoln Navigator 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 Lincoln Navigator 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 Lincoln Navigator 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 Lincoln Navigator 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 Lincoln Navigator 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 Lincoln Navigator 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.

Real Customers, Real Reviews

It’s been about 3 weeks now since I installed the conversion kit on my Navigator. I did it myself in my driveway. It was relatively simple, however I do not recommend doing this without a friend. It was a little difficult to do on my own with *limited* tools. Took me about 7 hours with a few issues that slowed me down. With a friend and the proper tools this can be done in less than four hours I’m sure.
The ride has significantly improved since day 1 of the install now (pretty stiff before they settle). It is a great ride now, it’s not as quiet as the air ride, but I can’t even hardly notice a difference in ride quality. Now I never have to worry about my failing compressor and the time it would take to air up my suspension, or the few times my fronts were riding on the bump stops.
I highly recommend anyone contemplating this kit buy it and get it done before your air ride inevitably fails.
“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”
“Just bought this my 2005 Navigator. MAN WHAT a DIFFERENCE. Can’t believe how awesome my Navi rides. I love the piece of mind of not worrying about my air ride and the red springs look cool. Thanks Strutmasters!”
We had installed the Navigator Conversion Kit with no problem and returned the car back to our customer yesterday.
I’m satisfied they fit perfect. Thanks your product is the best.
My overall experience from conversations on the phone with the techs, to the instructions provided were great and I would not change anything.
I purchased the coil over kit for my wife’s 2004 navigator. Strutmasters was easy to deal with and I received my order in only 4 days. It only took 3 hours to install the new struts and the ride and drive is as good, if not better than the factory air ride.
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
Thank you for having these replacement parts. I wish I had known about these a year ago, before I spent $1600 on new air bags and a compressor just on the front. I am not mechanically inclined but found these struts easy to install. Thank you again.
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!
I bought struts to convert air suspension of my Navigator 2006. Very happy with it! Service and shipping was excellent. Thank you.
“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.”
If you are having problems with your air ride you are going to regret not buying this kit! I have been fixing things here and there with my air ride until I bought this. Its will just Nickel and dime you! The parts are very high quality and were very easy to install. It took my dad and his friend 50 min each to replace them. I have been told by 3 mechanics that Strutmasters makes the best conversion kit they have seen! My truck rides better then it ever has. I feel much safer driving. The truck sits so nice, before the conversion the back sat abour 4 inches lower than the back. This is the way to go! Thank you Strutmasters for coming up with such a great product! Also excellent customer service. I placed my order over the phone on a Wednesday and had the kit by Friday!
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.
I purchased the air conversion kit for my 2004 Lincoln Navigator, and the ride is so smooth that it feels like a brand new vehicle.
Service was great, car came out great and mechanic was impressed on how easy every thing came for installation.
“I would be remiss if I did not contact you and tell you of the “Outstanding” customer service and information that I received from Vito. After speaking with Vito on several occasions he was the deciding factor in me deciding to purchase the Air Suspension Replacement Kit from Strutmasters. After being burned by my local repair guy (could not fix the problem without costing me even more money) I was more than a little apprehensive about this entire process but Vito provided me with a great education on this problem and process and made me very comfortable buying from your Company. The parts arrived when expected (and had the mechanic done what he should have done – I would have had my vehicle back on the same day), and per my mechanic they were very well made. My mechanic (kindly –due to me being ill) picked up my Navigator at 9AM and returned it to me by 3:30 on the same day, I have been very happy with the height and the comfort of the ride. My mechanic commented favorably on the quality of the parts he received an the ease of the process (although there was no reflection of this in the charges to me)
I just wanted you to know what a great job Vito did in serving me as a customer.
Everything went well. Thanks again. Tim
I kick myself for not finding you guys a few years ago when I started battling the air ride on my wife’s urban assault vehicle. Long story short……after replacing a compressor and two level ride sensors we still were in lowrider mode! Of course temperature played a role (anytime it dropped below 40 degrees F). I bought your XN-44 and installed them over the weekend. (the comment about “if you can do a brake job you can install these units”…..is accurate! For a self proclaimed shade tree mechanic it took me 3 hours to complete with no lift. The wife thanks me everyday for not having to battle the rough ride. Well done Strutmasters……well done indeed!
“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.
03 Lincoln Navigator”
Installed the strutmaster kit on my 2003 Lincoln Navigator and my truck rides great I can’t tell any difference between these and the air ride. It took me a little over four hours to complete installation. My compressor went out and one of the front air bags and I didn’t want to replace and then have another one fail. Great product.
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.
“Well, I didn’t want to do this at first, as sooo many people that did the air ride conversion have been unhappy, but none of them have used strutmasters kit… if they have, they would say it is nearly the same as the air ride… I wish I would have just done this from the start instead of wasting the money I did on the air ride system, which never did get fixed correctly.
I would say it’s about 85% the same – but the trade off is that I will never have to worry about waking up in the morning, going out to my truck, and have it sitting low, and not pumping up…
All in All, it was a wise choice – I didn’t like that they charged me a $5 handling fee and didn’t tell me about this, (thus the 4 out of 5 stars) but as I say, you can’t beat these… they are heavier than I expected in the boxes, etc… so that was a nice surprise! The springs are beefy, and I love the red power coated paint job!
I purchased a set of Struts after having the air ride go out on my Lincoln Navigator. This is my 3rd one so I know the money pit it can become taking it to the dealer. The kit was easy to install after tracking down the nessecary tools but all in all saved me over $1200 over taking it to the dealer. My truck rides better than new. I have the kneel down function and Mike in customer support was outstanding. Very knowledgable and eager to help. If you need to replace that destined to fail air ride, this is the solution. I have my friend so impressed he is replacing his and it isnt even broken.
Thank you Strutmasters! I have had issues with my Air Suspension system for 3 years now and $3,000 dollars later the mechanics still cannot pin point the issue. I removed the air struts and replaced them with your conversion kit. The instructions and videos made it easy. I am not a mechanic, but your videos made it real easy. thank you so much. The Nav rides great now and no more worries about the suspension. Awesome product. You have a customer for life.
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.
It’s been 3 weeks since I had the kit installed and I’m very happy. I should have done this years and thousands of dollars ago. Thank you Strutmasters for a great product. I will be recommending you guys to all my friends that have air suspension problems.
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.

“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)
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.
