Why Choose Strutmasters Instead Of Those Other Guys
The assorted parts that make up the air suspension system on the 02-09 GMC Envoy must always function in sync. The entire system needs repair if only one part stops working. Strutmasters' unique air to non-air suspension conversion kit eliminates this dependency for good. This kit, made in the USA, includes two Eibach coil springs. The kit was designed to be an affordable direct replacement alternative to dealer repair- no modifications are required before it's installed! The parts are high quality and come with a Lifetime Limited Warranty. The kit is installed in as little as one hour per wheel, thanks to the accompanying detailed instruction manual. The suspension warning light typically turns off after about thirty minutes, too. If more help is needed, our certified technicians are available to answer your questions and concerns. Lastly, watch our installation videos that are available to view online.
How Do I know If My Envoy Air Suspension is failing?
If the 02-09 GMC Envoy is not meeting and maintaining its proper ride height, a bad suspension may be to blame. Look for these signs of a failed or leaking air suspension before it’s too late and total failure sets in. The most noticeable is a sudden drop or squatting of three to five inches in the rear of the vehicle. A lean from one side to the other could be present. Other components may wear out, too. The air compressor, for example, may stop working or may run too often (in this case it is loud and noisy). Lastly, an illuminated suspension warning light on the dashboard is an obvious red flag for suspension trouble. If any of these symptoms are present, get the suspension fixed promptly.

Suspension Components List
The 2002-2009 GMC Envoy is built with the following rear 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 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.
2002-2009 GMC Envoy Shock Absorbers (x2) - has metal tubing filled with gas-charged hydraulic fluid in order to reduce or dampen vibration and bounciness caused by travel on a rough surfaces. Some models dampening may be controlled by the suspension control module and can be very costly to replace.
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 springs in order to adjust the height of the vehicle, respectively.
2002-2009 GMC Envoy Solenoids (x2) - 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.
2002-2009 GMC Envoy 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 air springs 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.

Real Customers, Real Reviews
Read reviews from people just like you looking for the perfect solution for their suspension needs.
I feel that you have a great product line and Brad was very courteous and helpful during the sales transaction. I ordered the coil spring set along with the shocks to replace the old air ride system in my Olds Bravada. I am impressed with your product line and will tell others about it. Thanks for a workable solution to a very common problem
Everything went great and thank you for your service!
“I was very satisfied with your product. It did as was advertised. Thanks so much.
Thank you for sending my order so fast. I was very satisfied and will use your site again if I need some thing.
What a total difference this adds to the vehicle. I don’t think I have even see it sit up this good before. The ride is great. I will recommend this conversion kit to anyone with air ride suspension. It is so easy to install and the cost for labor can be so much cheaper for a customer than putting in a new air ride system.
This was not the first time I’ve had to do this kind of conversion to a vehicle that I’ve owned, but like the first time Strutmasters made it easy to do. Before I used the conversion kit my Buick Rainier looked like (to quote my dad)” it was haulin’ a load of moonshine”. Now it rides just like it did before the airbag went bad. Thanks again Strutmasters. You guys really came through.
“Re: Air suspension replacement kit.
Have to say I was skeptical at first. Usually I’m the type of person that wants factory parts. However, it’s clear many GM cars have the exact same air suspension deterioration issues, and the cost to fix is fairly large.
My Strutmasters order shipped right away. It was 200 + an extra 100 for overnight shipping. My mechanic charged $200 to install the springs/shocks and disconnect the compressor. Overall, 500 isn’t bad and made me happy to order from Strutmasters.
My 02 GMC Envoy is now in great shape with a rear end that doesn’t bottom out if left a day or two. The rear was a bit high at first but is already settling. Product seems great, the company reputable. My mechanic even vouched for them.
It’s only been a couple weeks, but so far, no complaints. I’d definitely recommend Strutmasters to other folks in the same situation. Hopefully, things continue to work as well as they do now. Smooth ride! Can’t tell any difference. ”
