They work great. It is wonderful to have selectable lockers. There is no erroneous popping sounds coming from them, as they do not unload mechanically. They are best used in straight lines, especially the steering axle. It is very difficult to turn, when the locker is engaged, as there is no loading, and releasing of the torque, as in mechanical lockers. One thing you may want to do some research on, is electric lockers. It is probably easier to rupture a air line, then to loose an electrical signal. Also, because of not having to buy a mini air compressor, they may actually be cheaper. One of the newer electric lockers is Eaton.
