Replaced Components
The 1991-1996 Buick Roadmaster Wagon is built with the following suspension components: 1991-1996 Buick Roadmaster Wagon 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. 1991-1996 Buick Roadmaster Wagon 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. 1991-1996 Buick Roadmaster Wagon 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. 1991-1996 Buick Roadmaster Wagon 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. 1991-1996 Buick Roadmaster Wagon 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. 1991-1996 Buick Roadmaster Wagon 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. 1991-1996 Buick Roadmaster Wagon 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. 1991-1996 Buick Roadmaster Wagon Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicles correct ride height. 1991-1996 Buick Roadmaster Wagon 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.

Suspension Failure Signs
Early detection of a failed or leaking air suspension system on the 1991-1996 Buick Roadmaster Wagon is the key to avoiding total failure. Look for these classic signs that indicate the air suspension system is going bad, before it's too late and total failure sets in. A suddenly uneven height difference between different sides of the Roadmaster Wagon is typical. Usually, the rear end will sag while the front end remains inflated. This can give the vehicle the appearance of “squatting down.” There may be a shifting lean from side to side. These height imbalances, if not fixed promptly, will wear out the air compressor. If the air compressor stops working or runs too often then suspension failure will advance. The Roadmaster owner should look for an illuminated suspension warning light on the instrument cluster to confirm.

OEM Replacement Cost
'+ Rear Shocks ($263/shock) + Coil Springs ($185/Coil Springs) = TOTAL: Over $1,000 (and that doesn't even include replacing electronic components that are known to fail such as the height sensors).
Strutmasters' air to non-air suspension conversion kit saves Buick Roadmaster Wagon owners time, frustration, and money when the air suspension system goes bad. The kit, manufactured in the USA, permanently eliminates the ride's reliance on complicated air parts always working in sync. It comes complete with two pre-assembled coilover shocks that can be installed in as little as one hour per wheel, with just a few bolts each. Say goodbye to the air ride headache for good. Detailed instructions, technical support from ASE certified experts, and online installation videos are available to assist the customer with the repair. Strutmasters offers peace of mind with its Lifetime Limited Warranty. But most appealing to Roadmaster Wagon owners is the low price. Without sacrificing quality, this kit costs a fraction of the price of dealership direct replacement and individual part replacement.
