Why Choose Strutmasters Instead Of Those Other Guys

The assorted parts that make up the air suspension system on the 2004-2007 Buick Rainier must always function in sync. When one part stops working, the system needs a repair. Strutmasters' air to non-air suspension conversion kit eliminates this inconvenient and expensive dependency. The kit, made in America, includes two cold-wound steel Eibach coil springs and two shocks for the rear end of the Rainier. The kit is installed without any modifications- it's a direct replacement. It saves time and frustration, too. The kit can be installed in as little as one hour per wheel. But it is the low price that seals the deal for most of our customers. A closer look at the cost difference between replacing a faulty air suspension system and choosing an air to non-air suspension conversion kit will shed light on considerable savings. Review three different prices: that of repairing the air suspension system at the Buick dealership, that of installing aftermarket air suspension parts on the Rainier individually, and that of installing a Strutmasters air to non-air suspension conversion kit. Keep in mind, excellent customer service is a priceless benefit. Our ASE certified technicians are available to answer your questions when you need help, and installation videos are available to view online.

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

If the 2004-2007 Buick Rainier is unable to meet and maintain its proper ride height, its air suspension system may be leaking or failed. Early diagnosis of a bad suspension system is the key to avoiding total failure. Look for a sudden difference in height between different sides of the Rainier. Typically, front end will remain inflated while the rear end sags.The air compressor, for example, may have stopped working or may run too often. One final red flag is an illuminated suspension warning light on the dashboard. Any and all of these issues should be fixed immediately to avoid further damage to the vehicle.

Suspension Components List

The 2004-2007 Buick Rainier is built with the following suspension components:  2004-2007 Buick Rainier Air Springs (x2)- Rather than metal coil springs, these springs use pressurized air to hold the vehicle off of its wheels and cushion the impact of rough road surfaces. They are the primary cause of all leaks in an air suspension system. Since they wear out at about the same rate, in order to properly repair an air suspension they should all be replaced at the same time.  2004-2007 Buick Rainier Struts (x2)- These metal columns are filled with a hydraulic fluid that is charged with gas. They connect to the wheels of a vehicle in order to absorb the bounce from travel over rough surfaces.   2004-2007 Buick Rainier Shock Absorbers (x2)- Located in the rear of the vehicle, these shocks control the wheel-to-ground contact.  2004-2007 Buick Rainier Height Sensors (x2)- These sensors detect the height of the vehicle's ride and send that information to the suspension control module. They are moving parts and will eventually wear out and need replacement.   2004-2007 Buick Rainier Air Lines- These hoses deliver pressurized air from the compressor to its air springs.   2004-2007 Buick Rainier Solenoids (x2)- These plastic pieces are the connection between the suspension components, electrical connections and the suspension module. Their job is to regulate the air pressure for each spring. Solenoids will eventually start to leak and cause the compressor to overwork as it tries to compensate. This will wear out the compressor and other components well before the expected end of their working life.  Compressor Assembly- Generates pressurized air and sends it to the components of an air suspension. When other parts of that system start leaking, the compressor will work harder to try to keep the system inflated. This will lead to the compressor wearing out prematurely. As one of the most expensive and critical components of the air suspension system, it is very costly and difficult to service or replace.  2004-2007 Buick Rainier Dryer- Prevents the build-up of moisture inside of the air suspension system.  2004-2007 Buick Rainier Suspension Control Module- This module is a small computer that maintains the vehicle's ride height by managing all of the functions of the air suspension system.  2004-2007 Buick Rainier O-rings- These o-rings keep the air lines of the suspension system clean and efficient by maintaining a seal where the lines connect.

Great ride is back, Devon’s help was great. Answered all my questions. Installation guide was on the money.

I called Strutmasters and I talked to Will. I told him the problem I was having with my Buick Rainer. The rear air bags had failed and my suspension was just about dragging the ground. Will told me what I would need. I got my conversion kit in two day. I took it to a friends shop and we installed in about 30 minutes. We took both rear tires off and both rear shocks, we then twisted the air bags half a turn, they dropped down, I cut both air lines, wire tied the height sensors in the up position, prayed down slightly on the suspension, slipped the coil springs in, put the new shocks and tires on and was done.Great fit.Thank you Will ans Strut Masters, you will get all my suspension business, and I have been telling all my friends about you.

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,

Dennis G.”

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”
