B from Saint Louis, MO said, "It was four years ago when I was first introduced to the Ground Force Product. At that time I purchased a lowering kit for my 2002 Ford Expedition. I was so impressed with the product that I purchased a second kit for my 2003 Hummer H2. They both look great, and when I think of lowering any vehicle, I think Ground Force first."
