This piece of scrap lasted less than a month before apparently bursting the seals inside. He filled part of the airbag with shock absorber oil, which in turn seeped through the air compressor filter and into the compressor, destroying it as well. This is an 09 Tahoe family car. Don't buy them, trust me you will regret it. Now, in addition to new shock absorbers, I also need a new compressor, which was replaced just a month before the shock absorbers!
