Why Choose Strutmasters Instead Of Those Other Guys

The original air suspension system on the 03-06 Lincoln Navigator 4x4 is made up of assorted parts that must each function in sync. When one part is out of sync, a repair or replacement is needed. This gets costly as trips back and forth to the Lincoln dealership really add up. We knew there had to be a better way- so we created our air to non-air suspension conversion kit. It’s a high quality, yet affordable, direct replacement alternative that doesn’t require you bringing your Navigator to the dealer. This kit includes two pre-assembled front coilover struts with progressive rate springs and two pre-assembled rear coilover struts with progressive rate springs. DIYers love that the kit is installed in as little as one hour per wheel, thanks to the detailed instructions. Our positive customer reviews prove the kit saves time, frustration, and money. The high quality and the low price is what convinced our customers to make the switch when choosing between an air vs non-air suspension system. Review our price comparisons for your three options when you have a failed air suspension: that of repairing your air suspension system at the Lincoln dealer, that of installing aftermarket air suspension parts on the Navigator piece-by-piece, and that of getting rid of the air ride headache forever by installing a Strutmasters suspension conversion kit for the rear of the Navigator 4x4.

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

If you think your 03-06 Lincoln Navigator is not meeting and maintaining its proper ride height, the air suspension system may be going bad or leaking. Look for these common signs to help you properly diagnose the situation. Left running too long, other components will wear out and total failure will set in. The most noticeable sign is a sudden uneven difference in height from the front to the rear of the Navigator. Typically, with this model, the rear end suspension will fail first (sag) causing the front to look overly inflated. This makes the Navigator look like it’s squatting down in the rear. Visible cracks in the rear air springs, caused by dry rot, will need replacement and indicate a bad suspension problem. An illuminated suspension warning light on the instrument cluster is an obvious red flag. And lastly, if you notice the air compressor has stopped working or runs too long (longer than 15-20 seconds at a time), you may need an air suspension direct replacement. You have options, but you should act quickly for the wellbeing of your vehicle.

Suspension Components List

The 2003-2006 Lincoln Navigator 4WD is built with the following suspension components:

2003-2006 Lincoln Navigator 4WD Air Springs (x2)- 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 4WD Coil Springs (x2)- Coil springs hold the vehicle up but be careful, they are rated for and designed to work with the rest of the suspension system, so when you change air shocks to passive shocks, then you will need a different rated coil spring that works well with the new type of shocksshock.

2003-2006 Lincoln Navigator 4WD Torsion Bar- on some 4x4 models. Adjustable horizontal bar on the front of the vehicle that holds the vehicle off the ground.

2003-2006 Lincoln Navigator 4WD Shock Absorbers- a 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.

2003-2006 Lincoln Navigator 4WD 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 4WD Compressor- This vehicle is equipped with one air suspension compressor. The compressor is responsible for pumping up the air springs and shocks. When the air suspension starts leaking, the compressor is forced to run continuously to try and keep the air springs inflated. After a couple of days of running non-stop, the compressor will burn itself out. Replacing the compressor is a timely and expensive project to undertake.

2003-2006 Lincoln Navigator 4WD Dryer Assembly- This vehicle is equipped with a dryer assembly. The dryer assembly is responsible for getting moisture out of the air lines. Once the air suspension parts start to leak, moisture will build up throughout the air system. Moisture damages the air suspension components from the inside out. The dryer must be replaced whenever the compressor is replaced to prevent further damage.

2003-2006 Lincoln Navigator 4WD Suspension Control Module- This vehicle is equipped with a suspension control module. This module is the brain of the suspension system and it reads all of the signals that are being sent by the height sensors and determines if the vehicle needs to be raised or lowered.

2003-2006 Lincoln Navigator 4WD 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.
