long-icon-questionWhy Choose Strutmasters?

Why choose the Conversion Kit over replacing the air suspension system on your 1985-1992 Cadillac Fleetwood?

The air suspension system on the Cadillac Fleetwood is made of assorted parts that must always work together. If one component stops working, the rest follow suit. Strutmasters' air to non-air suspension conversion kit is an affordable direct replacement solution that permanently eliminates this faulty reliance. The kit, made in the USA, includes two custom-rated Eibach coil springs and two hydraulic fluid gas-charged struts for the rear. Say goodbye to failed onboard compressors and level sensors for good! The kit can be installed in as little as one hour per wheel. Detailed instructions and online installation videos offer precise directions. For further assistance, Strutmasters' ASE certified experts offer technical support over the phone. Without sacrificing quality, the kit costs a fraction of the prices of dealer repair and individual part replacement. This coilover suspension conversion kit saves Cadillac Fleetwood owners time, frustration, and money when the air suspension system goes bad.

long-icon-xIs Your Suspension Failing?

How do I know if my 1985-1992 Cadillac Fleetwood Air Suspension is failing?

An inability of the 1985-1992 Cadillac Fleetwood to reach and maintain the proper ride height is an indicator that the air suspension system is going bad. Look for these classic signs that point to a failed or leaking air suspension system before it's too late and total failure sets in. A sagging rear end is typically seen. This gives the illusion the Fleetwood is squatting down in the rear. A shifting lean from side to side may be present. Height imbalances such as these will wear out the air compressor over time. If the air compressor stops working or runs too often then suspension failure will progress. An illuminated warning light on the instrument panel will confirm this diagnosis. The Fleetwood owner should have any suspension issue fixed as soon as it presents itself.

long-icon-gearVehicle Components

What kind of suspension does my 1985-1992 Cadillac Fleetwood have?

The 1985-1992 Cadillac Fleetwood (FWD) is built with the following rear suspension components:

1985-1992 Cadillac Fleetwood (FWD) Air Struts (x2) - struts that contain an air bladder whose dampening capabilities is controlled by the suspension control module; they serve two purposes. These connect the wheel of a vehicle to the driving surface in order to reduce the effects of vertical travel on a rough surface which controls the bounciness, and therefore comfort, of a vehicle. They also help maintain the vehicles correct ride height, especially whenever the amount of load put onto the vehicle changes.

1985-1992 Cadillac Fleetwood (FWD) Coil Springs (x2) - what we love! 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 shocks.

1985-1992 Cadillac Fleetwood (FWD) Height Sensors (x2) - 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.

1985-1992 Cadillac Fleetwood (FWD) Air Lines - tubes that run from a compressor to the air which carry pressurized air to the air struts in order to adjust the height of the vehicle, respectively.

1985-1992 Cadillac Fleetwood (FWD) Compressor Assembly - 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.

1985-1992 Cadillac Fleetwood (FWD) Dryer - prevents moisture build-up inside of air suspension parts.

1985-1992 Cadillac Fleetwood (FWD) Suspension Control Module - a computer which is responsible for the operations of the air suspension system and maintaining the vehicle’s correct ride height.

1985-1992 Cadillac Fleetwood (FWD) 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.
