There's a few shops around the area. 4WheelParts is one of the bigger ones, as newracer already said. There is also High Country 4x4 off of Santa Fe and Hampden, one in Ft. Collins off of 287 (but I don't know the name of that one), another in Boulder I believe, and numerous other vendors that you can order online from. Some of these are companies like offroadtoystore.com, Rokmen, Crawlertech, and others. You should check out Colorado4x4.org and go to the vendor section and you can get an idea of what you are looking for.
