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!”
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.
“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 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.
“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!
“Many thanks to you guys at STRUTMASTERS !!!! My wife’s 2003 Lincoln Navigator was diagnosed with Air Bag Cancer. I checked everywhere for a solution because my wife LOVES her car. Every solution form Lincoln said $$$$ which we could not afford. I began to put my fingers to the Cyber Net Keyboard for solutions and found your website! The video made it look a little bit TOO easy (if you can do brakes . . .. I checked the BBB for their complaint issues and found them to be in good standings. I was a little hesitant to order over the internet, so I used a debit card and WHOLLA! I ordered it Sunday and it came Wed afternoon! I had all the tools EXCEPT the one to remove the large bolts from the bottom Strut, so I enlisted the aide of my Mechanic Mr. Chase of Bernard’s Auto of Bklyn, NY who installed all 4 for a minimal price. Everything (including the Struts) came to UNDER $1000!!!! So if your tired of chasing the Dealership Rainbow for a solution, try STRUTMASTERS for a cure to Air Bag Cancer and give your ride a new LIFT on life.

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
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 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.
“This was one of the best choices I ever made to change the air suspension on my navigator,no more problems,save money,great product,very helpful rep.
thanks again for a great product Gord”
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!
I have waited a few months before writing a review on the 4-Wheel Air Suspension Conversion Kit with eibach springs the truck does sit a little higher but not much still looks great in my opinion the truck rides much better than with the air ride it handles corners 100 times better not as much body roll goes over speed bumps and dips better not as bouncy would recommend this kit
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
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.
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.
As always Strutmasters gets me the right parts and fast shipping even to me in Hawaii.Have only used Strutmasters for my company the last 8 years for all suspension kits.Jay is a super great and knowledgeable person.Kits even get better after time this one came with Eibach coils.Highly recommend Strutmasters to anyone looking for suspension components. Mahalo to the entire Strutmaster family for making quality kits at a great price and proper fit always.
I ordered the complete kit for my Lincoln Navigator. Havent installed it yet due to weather but the products are extremely heavy duty and high quality. The only recommendation I have for Strut Masters is possibly changing the color from red to black on the coil springs. Red stands out inside the fender well and on an all black vehicle, its slightly unsightly.
“The left rear airbag on my 2003 Navigator went down at 90,000 miles. I read the stories on the forums and decided to abandon the stock air suspension. I am certain it was the correct decision. The kit was at my home in less than a week. I installed it in my driveway in about 2 hours. It was easier than doing a brake job. The ride is great! And I have piece of mind knowing I will never have to worry about it again.
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.
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.
“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.
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.
Customer service was great, thanks Brad and Evette for all your help…..i was very skeptical about purchasing this kit because of the different reviews good and bad. Well I purchased it for my 03 lincoln navigator with 24″ rims and I love it, I can’t tell the difference from the ride before the kit, one thing I will say is that I think the big tires made the kit look better , if your tires are smaller than 24″ it might look funny(which was one review I read)but not so sure. I’m glad I didn’t get the lift kit because it would have made my truck sit up too high and look weird
Excellent quality & great handling. Would recommend to anyone as alternate to anyone considering repairing/replacing their air suspension. A+
“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.
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.
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!
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.
