How It Works And Why It Fails: Buick Rainier And Similar GM Midsize SUVs

Learn how the air suspension system works and why it fails on the Buick Rainier and similar GM midsize SUV models -- Chevy Trailblazer, GMC Envoy, Oldsmobile Bravada, Saab 9-7x and Isuzu Ascender.

Regardless of whether the vehicle has a Buick logo or one of the others, if you are checking out this video, your intermittent problem with the air suspension system has likely become permanent.

Millions of these GM midsize sport utility vehicles were made with an air suspension system at the rear. This system featured a pair of rubber air springs (also known as air bags) that rely on sensors and a computer to work properly.

As you will see in the video, the most common cause of failure in this system happens when tiny cracks in the rubber of the air springs cause leaks and eventually kill the onboard air compressor. Instead of chasing countless replacement parts that are expensive and hard to find, thousands of mechanic across the country recommend installation of a Strutmasters suspension conversion kit.

The Strutmasters product is simple to install and eliminates having to worry about what is going to fail next in the factory system.

Since enough time and mileage has passed for the air suspension to fail, the front struts are probably worn out too. Strutmasters makes completely assembled front struts for these vehicles. Give the Strutmasters team a call at 866-597-2377 for details on a special money-saving offer on all four wheels. For even better service, jot down your complete vehicle ID number (VIN) prior to calling.

Strutmasters founder Chip Lofton was the first to offer a fully assembled suspension conversion kit when the air suspension failed on his personal Lincoln in 1999. The company is still headquartered in North Carolina, where Lofton leads a team that strives to provide the best products and customer service in the industry. They use premium steel coil springs that are made exclusively for them in America. All of their conversion kits are assembled in small batches by experienced employees to ensure the highest quality.

Some customers have spent thousands (parts and labor) chasing a failing factory system. Don't learn the hard way! Avoid multiple repairs that come with fixing the existing system (especially with cheap, imitation parts). Fix It Once, Fix It Right with the original -- Strutmasters!
