Bilstein DOES make a 5100 for stock height trucks (or 0-2" lift as they call it). Genos garage can help you get the correct part#'s and they have more then fair prices as well as excellent customer service. It is possible that you might get a SLIGHTLY better price from eShocks.com, but I believe in supporting Genos just tio make sure that they will be around when I need them, plus their prices ARE competitive.
