These are TIMKEN wheel hub unit bearings converted from 8x170 to 8x6.5 pattern for your 1999-2004 f250 f350 excursion single rear wheel Ford super duty. They are brand new. They will have minor imperfections from the nature of restuding them. I can do any brand or even used hubs if shipped to me as well. These are great for people wanting doing superduty swaps to their OBS fords or SAS swap on Chevy Duramax. i have 05-10 hubs as well for $265 a piece. I also sell 11+ just currently dont stock them due to lack of demand on those. just send me a message for any questions or requests. This AD is for 1ea hub. you will need to purchase 2ea for a complete front set.
