long-icon-questionWhy Choose Strutmasters?

Why choose the Conversion Kit over replacing the air suspension system on your 1993 Cadillac Seville 4.9L?

The various components that comprise the air suspension system on the 1993 Cadillac Seville 4.9L must always function in sync. This reliance is expensive and inefficient. Strutmasters' air to non-air suspension conversion kit eliminates this dependency for good. The kit, manufactured in America, comes complete with two rear coilover shocks and one electronic bypass that removes the service ride control message. The kit is a direct replacement, so no modifications are needed before it's installed. Customers typically get the kit installed in as little as one hour per wheel. Detailed instructions and online installation videos help guide a smooth repair. The quality parts are backed by Strutmasters' Lifetime Limited Warranty, which provides customers with peace of mind. The kit was designed to save Seville owners time, frustration, and a lot of money. In fact, the low price of the kit is what seals the deal for most customers. The kit costs a fraction of the price of dealership direct replacement and individual aftermarket part replacement.

long-icon-xIs Your Suspension Failing?

How do I know if my 1993 Cadillac Seville 4.9L Air Suspension is failing?

Look for the following classic signs that indicate the air suspension is leaking or going bad on the 1993 Cadillac Seville 4.9L. Early detection of a failed suspension is the key to avoiding total failure. An inability of the Seville to maintain the proper ride height is a major red flag. A sudden height variance between different sides of the Seville is also a common warning sign. This may look like one sagging end (typically the rear) and one inflated end (typically the front). This may give the illusion that the Seville is “squatting down” in the rear. There may also be a shifting lean from one side to the other. Other common symptoms include an illuminated suspension warning light on the instrument cluster and an improperly working air compressor. Height imbalances will wear out the air compressor over time.

long-icon-gearVehicle Components

What kind of suspension does my 1993 Cadillac Seville 4.9L have?

The 1993 Cadillac Seville 4.9L is built with the following suspension components:

1993 Cadillac Seville 4.9L Electronic Struts (x2)- 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 Cadillac Deville’s struts, while having coil-springs, use an electronic signal to stiffen or soften the dampening of the strut.

1993 Cadillac Seville 4.9L Shock Absorbers (x2)- 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 shock absorbers.

1993 Cadillac Seville 4.9L 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 shocks.

1993 Cadillac Seville 4.9L 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.

1993 Cadillac Seville 4.9L 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.

1993 Cadillac Seville 4.9L 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.

1993 Cadillac Seville 4.9L 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.

1993 Cadillac Seville 4.9L Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle’s correct ride height.

1993 Cadillac Seville 4.9L 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.
