Powertrax No-Slip for Ford 8.8 rear axle with open carrier (not limited slip). In good shape, performs excellent offroad and has decent road manners. Had it in my 89XJ but I don't go wheeling much anymore (work, work, work) so I'd rather run open and let someone else get some use out of it. It needs a spring kit which they have at Summit Racing for $17 since I lost one of them. $200 OBO.
