With the Ox Locker you also have the benefits of both an open differential and a spool at the pull of a lever. The Ox Locker is a cable driven locking differential that uses a single air-craft quality cable to engage the locker. When activated, both axle shafts are locked together into the equivalent of a spool providing 100% equal traction to both wheels of that axle with no differential of speed between the wheels of that axle. When the OX Locker is not activated, the differential operates as an open differential, providing the smooth, predictable handling characteristics for daily driving.
