Why Choose Strutmasters Instead Of Those Other Guys
You will pay a high cost for a direct replacement at the dealer. But here at Strutmasters, we pride ourselves on being The Suspension Experts. We already know about the big assortment of parts that make up your 2003-2006 Ford Expedition 4 Wheel air suspension. We also know they break easily, and thatâs why we created our specialty conversion kits. The kit eliminates the dependence on all those parts working properly and in sync in order for your suspension to function. The kit includes four completely pre-assembled coil-over struts that are installed with five bolts per strut and in about one hour per wheel. We designed the kit with our loyal DIYers in mind- our pictorial instruction guide, YouTube installation videos, and in-house technicians are all on hand to support your Ford Expedition suspension repair. The conversion saves you time and money. Now letâs take a look at the cost difference between choosing air vs non-air suspension system. We compare three prices to make it easy for you to see the difference: the price for repairing your air suspension system at the dealership, the price for installing aftermarket air suspension parts yourself, and finally the price of getting rid of the faulty air suspension completely and installing our brand new high quality coil-over suspension conversion kit. You will be glad you made the last choice.
How Do I know If My Expedition Air Suspension is failing?
You may be on this page because you already know your 2003-2006 Ford Expedition 4 Wheel has a failed or leaking air suspension. Or, you may not yet recognize the signs. Keep reading to learn about how you can diagnose a bad suspension on your Ford Expedition. The most frequently seen sign is a sudden noticeable uneven height difference between different sides of the vehicle. People often describe this as a “sagging” rear or front (the opposite side looks inflated). There might be a “leaning” to the left or right side. The entire vehicle may look like it’s squatting down low to the ground. Overall, if the ride height is dramatically different then you probably need a repair or replacement. Another universal tell-tale sign is if you see an illuminated warning light or message on the instrument cluster. A total failure of your suspension may have caused the air compressor to wear out. Check it- is it running too often? Not working anymore? All of these symptoms are giveaways that your suspension is bad, or is going bad. At this point it is not safe to be driving the Expedition on the road, is it may slam down on the ground with sudden stops.

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.

I bought the Strutmaster springs for a 03-06 Ford Expedition along with the readylift 3″ lift/level kit. holy hell does my truck not only ride better, but with the lift and level it looks 1000x better!! i paid a fraction for these then what it would have cost me to replace my front and read left side air bags along with dealership hourly shop rates. the product itself is a 5/5, the service of strutmasters is a 4.5/5 the 0.5 knock off is it does not specify that the readylift kit was not packaged and shipped with my struts, it was only written on the invoice which, who really looks at those most of the time? not me thats for sure. but thats only minor. so anyhow, BUY IT NOW, theres no question about this product. they specialize in the replacement of airbags and if only 1 airbag is failing, replace them all with the struts. you’ll be glad you did 🙂
