I have a powertrax for a 05 Chevy half ton for sale. 10 bolt 8.625 ring gear only!!! I am building my truck into a street machine and never use it not to mention I have too much power now for a lunchbox locker. I broke it and have been sent a replacement never installed in a vehilce so save a few bucks and get a brand new locker. $400 obo. Inbox me if interested
