I was referred to Ron and Ken by my cousin and a good friend as the only option if I was getting a suspension lift and larger tires on my GMC 2500. Their knowledge about lifts and larger tire kits is second to none! They installed the 5 inch Zone suspension lift with 35 inch tires. I could not be happier with their work. You may be able to find slightly lower prices if you shop them... but remember you get what you pay for! I highly recommend Custom Auto World! - Bill H. (5 star review on Google)
