Why Choose Strutmasters Instead Of Those Other Guys

When your 2003-2004 Lincoln Navigator air suspension system goes bad, you can either continue to take it to the dealership, or you can fix it once and fix it right. At Strutmasters, we have seen how the dependence on a complex network of interdependent parts can lead to constant air suspension headaches. That's why we created this kit to eliminate the dependency on all those expensive air and electronic suspension parts that are prone to fail. The kit includes four completely pre-assembled coil-over struts that bolt right in the same place as the original struts with no modifications needed. The averaged labor time is about one hour per wheel. The result is a ride quality closer to the original system than any other conversion kit on the market.  Our kit was made with our beloved DIYers in mind. If the packaged instructions and guide aren't enough, watch our installation videos on our YouTube channel or call one of our in-house technicians for assistance. The conversion kit is cost effective; it saves you lots of money on top of time and frustration. Let's take a look at the price difference between replacing air suspension vs a passive suspension conversion kit. Now we are going to compare three prices: The price for repairing your air suspension system with OE parts at the dealer; the price for installing aftermarket air suspension parts on your vehicle; and the price of getting rid of the air suspension heartache by installing a brand new coil-over suspension conversion kit. You will soon see why many customers choose Strutmasters over every other option.

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

Be on the lookout for common signs of a failed or leaking air suspension in your 2003-2004 Lincoln Navigator. The most obvious of those is a sudden drop of three to five inches of ride height in any of the wheels or noticeable difference in ride height between different sides of the Navigator. You may experience sagging in the rear or front or an overall appearance of the Navigator squatting down lower than usual. These are all tell-tale indicators of suspension failure. When this occurs, it’s common for the air compressor to cease working or run way too often (it will be loud and noisy). Other components may wear out. Your Navigator’s ride height should remain consistent. If it looks like it’s been “slammed” down to the ground, it's well past time for a repair. This situation is not only uncomfortable, it is outright dangerous. Don't waste time getting your suspension repaired.

Suspension Components List

The 2003-2004 Lincoln Navigator is built with the following suspension components:  2003-2004 Lincoln Navigator Air Struts (x4)- The hydraulic fluid-filled struts connect to each wheel and contain a perch upon which rests an air spring. Instead of a mechanical spring, these "air springs" use pressurized air to hold the vehicle off of the wheels and cushion the ride. These air sacks are by far the leading cause of all air suspension leaks. The hydraulic portion of the struts themselves help dampen vibration and control ride ride quality by reducing bounciness. If the vehicle has over 80,000 miles, it is likely the hydraulic strut itself is worn out, too.  2003-2004 Lincoln Navigator Height Sensors (x4)- These small linkages can be found next to each wheel of your Navigator. They are constantly monitoring the height of the vehicle at each wheel and sending that information back to the suspension control module. These components are one of many in air suspension that inevitably wear out with age.  2003-2004 Lincoln Navigator Air Lines- These tubes transfer pressurized air from the compressor to the air springs. This air is what is used to inflate the air springs and hold the vehicle up off of its wheels.  2003-2004 Lincoln Navigator Solenoids (x4)- These L-shaped plastic components work together with the suspension computer to regulate the air pressure in each air spring on your Navigator. As they get older, they will start to leak, causing other components in the air suspension to pick up the slack and start to deteriorate much more quickly.  2003-2004 Lincoln Navigator Compressor- The air in the air springs is generated by the compressor using mechanical force. This compressor also pumps that air into the rest of the system. Once components like the solenoids or air springs start to leak or fail, the compressor usually responds by working harder. This will, in turn, lead to early failure of the compressor, one of the most expensive components in an air suspension.  2003-2004 Lincoln Navigator Dryer Assembly- The dryer is essential to the health of the air suspension system. It removes moisture, which can damage the air suspension components from the inside out. It is usually replaced along with the compressor.  2003-2004 Lincoln Navigator Suspension Control Module- This small computer manages the diagnostic functions of the air suspension system and also uses information from the ride height sensors to maintain your Navigator's correct ride height.  2003-2004 Lincoln Navigator O-rings- These rubber o-rings maintain the seals where the air lines connect. This ensures that the system is both clean and efficient. They should be replaced whenever the air suspension is serviced.
