Why Choose Strutmasters Instead Of Those Other Guys

The original air suspension system on the 03-06 Ford Expedition 4x4 is made up of assorted parts that must function in sync, or else the suspension does not work properly. We knew there had to be a cost effective and more reliable way to fix a failed air suspension system, as opposed to dealership direct replacement. We built this air to non-air suspension conversion kit to fill this void in the market. This kit FX24E 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 it is installed in as little as one hour per wheel, thanks to the detailed instruction manual. Positive customer reviews confirm the kit saves time, frustration, and money. High quality and affordable- what’s not to like? The cost difference between choosing an air vs non-air suspension system is major. Please review our price comparison up above: that of repairing your air suspension system directly at the Ford dealer, that of installing aftermarket air suspension parts on your Expedition piece-by-piece, and that of getting rid of the faulty air ride headache for good by installing a brand new Strutmasters rear suspension conversion kit. Your wallet will be glad you chose the last option!

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

Look for these common signs of a failed or leaking air suspension system in your 2003-2006 Ford Expedition 4x4. You want to properly diagnose a bad suspension system before total failure sets in and it’s too late. The clearest sign of a failed suspension is a sudden difference in ride height from the front to the rear of the Expedition. Typically, in this Expedition, the rear will fail (looks like sagging) first making it look like it’s squatting down too low to the ground. An illuminated air suspension warning light is another major sign to look for. Visible cracks in the rear air springs (caused by dry rot) indicate rear air suspension failure. And lastly, listen to the air compressor. Has it stopped working or is it running too long (longer than 15-20 seconds at a time)? If so, a bad air suspension system may have caused it to wear out. If any of these signs are present, a repair or replacement may be in your near future.

Suspension Components List

The 2003-2006 Ford Expedition 4WD is built with the following suspension components:   2003-2006 Ford Expedition 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 Ford Expedition 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 Ford Expedition 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 Ford Expedition 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 Ford Expedition 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 Ford Expedition 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 Ford Expedition 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 Ford Expedition 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 Ford Expedition 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.
