I recently ordered an air compressor and rear shocks to replace my factory Autoride components on my Denali. The replacement parts you sent were perfect and easy to install. I had called my dealer first and they wanted $500 for the air compressor and I was able to purchase it from you for under $200. Wow! From what I read online these repairs would have been $2,400 at the dealer and I did it with your replacement parts for under $600. Thank you!!
