Does any one know or have purchased from the ebay site where they have the Bilstein's. it says that they work on 1500-3500's. Genos says they have ones specificlly desogned for CTD 4wd applications/... ... . Are these one and the same/..... Should I stick with the Genos or is there a stock # I need to look out for. My truck is approaching 100k and I need to swap out the originals... Thanks in advance
