long-icon-questionWhy Choose Strutmasters?

Why choose the Conversion Kit over replacing the air suspension system on your 2004-2007 Buick Rainier?

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.

long-icon-xIs Your Suspension Failing?

How do I know if my 2004-2007 Buick 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 uneven height difference between different sides of the Rainier. Typically, the rear end will sag and the front end will remain inflated. Left unchecked, this imbalance can wear out other vehicle components. 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 promptly.

long-icon-gearVehicle Components

What kind of suspension does my 2004-2007 Buick Rainier have?

The 2004-2007 Buick Rainier is built with the following suspension components:

2004-2007 Buick Rainier Air Springs (x2)- commonly referred to as air bags, a plastic and rubber bag that is fitted on top of the strut that uses pressurized air as a cushion instead of a metal coil spring to hold a vehicle off of the ground and off of its wheels. These are the number one cause of all air suspension leaks. 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.

2004-2007 Buick Rainier Struts (x2)- a type of shock absorber; has 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.; the air spring assembled on top of the strut is commonly referred to as an air strut.

2004-2007 Buick Rainier Shock Absorbers (x2)- these control the wheel-to-ground contact for the rear of this vehicle.

2004-2007 Buick Rainier 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.

2004-2007 Buick Rainier 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.

2004-2007 Buick Rainier Solenoids (x2)- 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.

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.

2004-2007 Buick Rainier Dryer- prevents moisture build-up inside of air suspension parts.

2004-2007 Buick Rainier Suspension Control Module- a computer which is responsible for the operations of the air suspension system and maintaining the vehicle’s correct ride height.

2004-2007 Buick Rainier 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.

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.
