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 at the GMC dealer, that of installing aftermarket air suspension parts piece-by-piece, and that of eliminating the air ride headache for good by installing the Strutmasters rear suspension conversion kit.

How Do I know If My Envoy Air Suspension is failing?

Even before the suspension warning light comes on in your GMC Envoy, there are a few signs that may help you detect suspension problems early on. For starters, you may notice a height differential between two sides of the vehicle. This is usually a sagging rear end and inflated front end due to problems with the rear suspension, but it may also present itself as a difference between the driver and passenger side of the vehicle. Another sign that should tip you off is if the compressor is noticeably noisy or running longer than 20 seconds per cycle. There may also be more wear and tear on your Envoy's components which are connected to the suspension than appropriate for the vehicle's age. Early detection is the key to avoiding major expenses and as such, all 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)- Known as air bags, these rubber and plastic sacs sit on top of the strut in an air suspension system. Rather than a metal coil spring, they use pressurized air to hold the car up off of its wheels and cushion the impact of rough road surfaces. If an air suspension is leaking, they are the most likely cause. Given that they all wear down at the same rate, all of them should be replaced in order to properly repair an air suspension.   2002-2009 GMC Envoy Struts (x2)- These metal tubes, which are filled with a gas-charged hydraulic fluid, are connected to the wheel of a vehicle. Their purpose is to limit the impact of rough road surfaces on the vehicle, controlling the comfort of the ride and insulating the vehicle's components from excess wear and tear. 2002-2009 GMC Envoy Shock Absorbers (x2)- These components absorb the wheel-to-ground contact for the rear of this vehicle.   2002-2009 GMC Envoy Height Sensors (x2)- These linkages, located next to each wheel of the vehicle, monitor the vehicle's ride height constantly, relaying that information to the suspension's computer. This allows the computer, or suspension control module, to determine whether or not an air spring needs to be inflated and by how much.   2002-2009 GMC Envoy Air Lines- These are rubber or plastic hoses that carry pressurized air from the compressor into the air springs so that they can inflate to the proper height.   2002-2009 GMC Envoy Solenoids (x2)- In an active suspension, these plastic pieces connect the electrical and mechanical parts of the suspension to the suspension control module. As they age, solenoids will begin to leak and cause the ride height sensors to activate the compressor. This will, in turn, cause the compressor to overwork as it attempts to keep the air springs inflated, leading to early failure of the system.   Compressor Assembly- The compressor is a machine that generates pressurized air and sends it to the air springs via the air hoses. When any part of the air suspension starts to fail, the compressor will usually try to pick up the slack and work harder to try and keep the system inflated. Unfortunately, not only is the compressor one of the central components of the entire air suspension system, it's also one of the most expensive and difficult to repair or replace.   2002-2009 GMC Envoy Dryer- The dryer keeps moisture, which can damage suspension components from the inside out, from building up inside of the system.   2002-2009 GMC Envoy Suspension Control Module- This is a small computer which manages all the functions of the air suspension system. It uses information from sensors to make sure the vehicle maintains the correct ride height.   2002-2009 GMC Envoy O-rings- Though small and inexpensive, these o-rings maintain the integrity of the entire system by keeping a seal where the air lines connect. They should be replaced every time the air suspension is repaired.

Worked out great. Easy to install. Priced right and fast shipping.

Name: | Location: Allen Park, MI United States | SKU: GB1RB

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.

“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)!

Thanks you,

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”
