A cable actuated selectable locker. It goes from open to locked with the throw of a lever. You don't have to deal with air, clutches, or electricity.

The Ox locker is extremely reliable and every part is milled from either billet or plate steel. There's nothing simpler than this design.

The included cover is substantially stronger than stock, and most other aftermarket covers.

The cable is aircraft quality and rated for 365,000 pulls.

Overall, it was worth every cent I paid. I don't have to worry about air leaks. It was a slight pain to dial in the cable adjustment, but once I did that, it works like a charm. I have nothing but praise for this locker.

The down-sides to this are that the cable can be vulnerable to rock hits if you happen to come down on an odd rock, but it seems very unlikely. If you do happen to rip the cable out, a bolt can be put in the hole and the locker will automatically remain locked.

PM me is you have any further questions. Bottom line: Extremely tough and well-crafted parts, simple design, reliable, worry-free.
