I would advise staying away from James Maddox affiliated with Chaos 4x4 in Michigan. He advertised Zip locker NIB and I received a locker that had a ring gear bolted to it and bearings pressed on and off. It is also missing about $175 in bearings, solenoid, bulkhead kit and the switch was crushed. He refuses to make it right (asked if he wanted me to just send back and refund, reimburse for missing parts and even split the difference on missing parts) and states "Well again like I said it is in the same condition that I received it in except for having the ring gear bolted to it." which I take to mean he also got it second hand but led me to believe otherwise. Buy with caution! I don't typically put people on blast but I feel like trust and integrity is something we need to maintain in this hobby and in these buy/sell groups. 🤷♂️ Next time going with my gut and buying from my dealer.
