Why Choose Strutmasters Instead Of Those Other Guys

Since 1999, Strutmasters has been focused on one thing: air, hydraulic and electronic suspension conversion. We are called the Suspension Experts because we invented this industry-changing suspension conversion almost twenty years ago. Our conversion kits are specifically designed right here in North Carolina by suspension specialists and are produced with only the highest quality components to guarantee that you're buying a quality product that will last. Our kits are the only ones that use Eibach coil springs made in California and are cold wound, meaning the production process doesn't degrade the steel and ensures the springs don'™t compress over time, keeping your Hummer H2 level. Your conversion kit comes with two premium rear shock absorbers, two Eibach coil springs and detailed instructions to do the installation yourself simply and easily. Our kits are a direct replacement for your air suspension and can be installed in about an hour per wheel. If you have any questions during the process our ASE certified tech support team is available to answer all your questions. Don'€™t be bothered with ongoing air suspension repairs, convert your Hummer'€™s suspension to a passive coil spring suspension and save yourself time and a ton of money.

How Do I know If My H2 Air Suspension is failing?

Similar to most vehicles with an air suspension, 2003-2009 Hummer H2 owners will usually find one day that the rear end of their car is sagging. This sagging position indicates a leak in your air suspension. A leak can occur in any one of several components: the airbag, air lines, or any of the seals. The first thing you’ll want to do is locate the air leak. This can occur in one or multiple locations so be sure to check the entire system. Fill a spray bottle with soapy water and spray it on the components. You will find bubbles forming in places where there are leaks. These leaks should be repaired immediately to avoid any further damage to your suspension system or unnecessary wear and tear on the compressor. If the compressor on your Hummer is running frequently or has become noisy it’s likely, that's another sign that you will have to replace it. It’s important to catch any suspension problems on your H2 early before they cause total suspension failure requiring a complete replacement of your air suspension and thousands of dollars out of your pocket.

Suspension Components List

The 2003-2009 Hummer H2 is built with the following rear suspension components: 2003-2009 Hummer H2 Air Springs (x2) - commonly known as air bags, this component is a rubber and plastic bag that sits atop the strut. It uses pressurized air to hold the vehicle off of the wheels and ground instead of a metal coil spring. These air springs are the leading cause of all air suspension failure. These air bags will all go bad around the same time, so if one is starting to fail, the others are likely to fail soon. All of them need to be replaced at the same time to properly repair the system. 2003-2009 Hummer H2 Shock Absorbers (x2) - These components have a metal tubing which is filled a gas-charged hydraulic fluid. They are connected to the wheel of the vehicle and help reduce the amount of vertical travel the vehicle endures going over rough surfaces, affecting the comfort of the vehicle's ride. 2003-2009 Hummer H2 Height Sensors (x2) - The height sensors are a connection located adjacent to each wheel of any vehicle with an electronic suspension. They are constantly measuring the height of the vehicle while it is on. This information is then reported back to the car's computer so it can decide whether or not the height needs to be adjusted. Like all moving parts, this component will wear out eventually. 2003-2009 Hummer H2 Air Lines- The air lines carry pressurized air from the compressor to the air springs to inflate them as needed to adjust the height of the vehicle. 2003-2009 Hummer H2 Solenoids (x2) - On vehicles with an active suspension, these L-shaped plastic components connect the electrical connection and of suspension component lines to the suspension control module. The solenoid is in charge of regulating the air pressure of each spring. When these solenoids begin to leak, they will cause the vehicle to sag or lean. This will cause a chain reaction in which the compressor will overwork itself trying to keep the air suspension inflated in order to level out the vehicle, eventually leading to it's failure. 2003-2009 Hummer H2 Compressor Assembly- This part generates pressurized air and sends it to the components of the active suspension. When the air suspension begins to leak, this compressor will work overtime as it tries to keep the vehicle level and at the proper ride height. This compressor will wear out around the same time as the air springs, meaning that once one needs replacing, so will the other. This is one of the most expensive components in an active suspension system and one of the most difficult to repair or replace. This particular compressor also acts as an external compressor, allowing the owner to inflate the tires. Our conversion kit will allow owners to continue to make use of this function once installing our conversion kit! 2003-2009 Hummer H2 Dryer- prevents moisture from building up inside of the components of the air suspension. 2003-2009 Hummer H2 Suspension Control Module- This is a small computer that manages the functions of the air suspension system, monitoring and maintaining it's ride height. 2003-2009 Hummer H2 O-rings- Although they are the smallest and least expensive parts of an active suspension system, they have the important job of maintaining a seal where the air lines connect. These should be replaced when undertaking any suspension repairs.

My H2 suffered from a saggy rear end. Here’s how Strutmasters took my truck’s rear suspension from zero to hero.


* Phone reps know their products, answered all my questions.
* Installation to convert from the stock H2 air ride to the Strutmasters coil was very straight-forward and was done in my dad’s (home) garage with a jack and some basic tools.
* Direct replacement parts is nearly the best way I could describe this kit. Knuckles weren’t busted, torches weren’t turned on, etc.
* Truck sits perfectly level with the kit and ride feels the same without the headache of a future sag issues. Feel a big weight lifted never having to worry about it again.


About 5 years ago, my air bags went bad and replaced them. I was good up until about a month ago when the compressor failed.

After dealing and fighting with the air ride now twice at this point, I had enough and started looking into a coil conversion because I never wanted to deal with the sag issue again.

I called Strutmasters and the representative that answered the phone had all the answers to my questions, ordered the HA1RB kit over the phone (my shocks were in questionable shape so ordered the kit that came with shocks while I’d be in that area) and in a few days the parts all arrived.

I was expecting this to be a bit of a project, but the the parts were almost literally direct replacements. Directions were to the point and pretty obvious.

The truck sits perfectly level and the ride feels the same, without the headache of ever having to worry about the air ride or rear sag ever again!

Anybody that’s tired of dealing with the air ride issues, absolutely check out the Strutmasters kits and save yourself the headache.

Strutmaster’s kits are going the be the first thing I mention to any other H2s I see with dragging rears.

Feel much more confident in the truck’s reliability!

Thanks Strutmasters!!

“This was my first time ordering, but it won’t be my last. Gary was very nice he helped me through every step he explained everything to us in detail even though I was a little annoying he was patient and very nice I would definitely order from them again.”

I contacted the dealer about changing my air suspension in my Hummer H2 to spring and they were charging me nearly $1700.00 for the entire job! Strutmasters sold me an excellent kit after giving me great advice AND recommend a local garage that installed the springs and shocks. Total cost: $750.00! Saved nearly a grand! They are simply the BEST at what they do.

I was a wreck when I first started. I was worried that my H2 was going to tip or something major was going to happen. I contacted strutmasters a couple days before the install for a walk through. He recommended spraying the parts down with PB Blaster. That worked like a charm! After getting the first side in, in the rear, my confidence grew. Impact wrench, breaker bar or torque wrench are a must. Love the product, and no more service air suspension light. The ride height looks a whole lot better!
