Why Choose Strutmasters Instead Of Those Other Guys
The assorted parts that make up the air suspension system on the 2002-2009 GMC Envoy must always remain in sync. When one part stops functioning, the system is defunct. As The Suspension Experts, we knew there had to be a more affordable and better quality alternative to direct replacement at the GMC dealership. The Strutmasters air to non-air suspension conversion kit, made in the USA, includes two cold-wound steel Eibach coil springs and two shocks for the rear end of the Envoy. DIYers love that the kit is installed in about one hour per wheel. Designed to save time and frustration, each kit includes detailed installation instructions. ASE certified technicians are available to answer questions about the repair, from start to finish. Installation videos are available to view online, too. The customer service is top-notch, but the low price is what convinces most of our customers to make the switch from an air to a non-air suspension system. Review the difference between the following three prices: that of repairing the air suspension system with Original Equipment parts at the GMC dealer; that of installing aftermarket air suspension replacement parts piece-by-piece; and that of eliminating the air suspension headaches for good by installing the Strutmasters rear suspension conversion kit.
How Do I know If My Envoy Air Suspension is failing?
If the 2002-2009 GMC Envoy is unable to reach and maintain its proper ride height, a failed or leaking air suspension system may be the cause. Look for the following common signs of a bad air suspension system, and resolve any issue before total failure sets in. Typically, the driver will notice a sudden three to five inch drop in the rear of the vehicle. Look for an illuminated suspension warning light on the dashboard. Lastly, check other vehicle components for signs that a bad suspension has caused them to wear out. The air compressor, for example, may have stopped working already. If it is running too often (noticeably noisy) then it may be in danger of wearing out soon. Any of these suspension problems should be fixed promptly. There are a variety of direct replacement and repair options available to resolve the issue.

Suspension Components List
The 2002-2009 GMC Envoy is built with the following suspension components:
2002-2009 GMC Envoy Air Springs (x2)- commonly referred to as air bags, a plastic and rubber bag that uses pressurized air as a cushion to support the weight of the vehicle. These rubber air springs are the number one cause of all air suspension leaks. Since air springs go bad at about the same rate, if one is leaking, the other one will not be far behind. For a proper repair, all of them need to be replaced at the same time.
2002-2009 GMC Envoy Shock Absorbers (x2)- these control the wheel-to-ground contact for the rear of this vehicle. Shocks dampen vibration and bounciness caused by rough road conditions.
2002-2009 GMC Envoy 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.
2002-2009 GMC Envoy Air Lines- tubes that run from a compressor to the air which carry pressurized air to the air bags in order to adjust the height of the vehicle, respectively.
2002-2009 GMC Envoy Solenoids (x2)- these plastic components work along with the 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.
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.
2002-2009 GMC Envoy Dryer- prevents moisture build-up inside of air suspension parts.
2002-2009 GMC Envoy Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle's correct ride height.
2002-2009 GMC Envoy 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.

Worked out great. Easy to install. Priced right and fast shipping.
First and foremost the Customer Service was extraordinary and extremely knowledgeable. When I received the product I was delightfully surprised of the quality. The cost was unheard of. It was so low. Once we received it took it to the vehicles dealership and they installed it for a fraction of what it would have cost. The cost would have been $1300.00 to have them install it elsewhere. Instead the total price was $529.00. I would tell any and all the quality and service was a “10”
“I thought you would like to learn about another success from installing your conversion kit!
This air suspension conversion kit finally eliminated the expensive and high maintenance Envoy factory air system. In less than an hour, this kit has returned the smooth factory ride (not to mention – no more low-rider, and no more noise from the air pump cycling on and off)!
The air-ride system was going bad on my 06 Rainier. The compressor was good but the air-bag springs were leaking. I would come out in the morning or after work and it would be sitting very low. After starting car the bags would pump up (most of the time) and i dealt with it like this for quite some time. I decided to go with the springs after rationalizing that if i put new air springs on it, the compressor would be the next to go and then the $$ would just continue to go up. Overall ride seems quite good and certainly a nice change from waiting for the bags to pump up every time i start the car. Install was really easy. I am by no means a gear head but i did most of this work myself with the my bro-in-law supervising and assisting when needed. Right tools are the biggest need. If doing this yourself jackstands are a must as you need to keep the car up on them after you remove shocks and air-springs to let the rear suspension lower out of its ride position. Overall good economical fix.
