air bag conversion with shock absorbers
Everything went to together without a hitch. Once the airbags were removed the springs and pads went right in. No straining what so ever. Took less than an hour on a lift.

Easy Install, Right Fit
The hardest part was removing the old air bag. I used a strap wrench to twist it off--one can get it from a plumbing supplier. The video was most helpful. I purchased the parts from IAAuto because they made the effort to make the video. My only criticism is the shipping was slow, but the price and fit were exceptional. I have extra vehicles, so I did not need to have the parts the next day.

Very satisfied
My air pump was weak and I had a leaking air bladder on my trailblazer ss. Saw the coil spring replacement on 1a auto. Called them to make sure it would work on my vehicle. After the rep spoke to a technical advisor I ordered it. It worked perfectly. No problems at all. And the price was less than I thought. Thanks a lot

Great value and easy to install!
ordered kit from 1A Auto and arrived 2 days before approximate arrival date. Everything was in the package and installation was a cinch. I had never installed shocks or springs before so using 1A Autos videos helped. Great value and prompt service.
