I had front and rear ARB Air Lockers installed on our Montero last year. Since we were sailing all of last summer, I haven’t had a chance to try them out on the trail yet, something I’ll rectify soon.
Until I get that post up, you might be interested in checking out how an air locker is actually installed. Jonathan Hanson from Overland Tech & Travel recently had one installed on his Tacoma and filmed the proceedings. Towards the end of the video, there’s some excellent under-the-truck footage showing them in action.
The video comprises “Part 2” of the process. He also wrote about “Part 1,” installing the compressor and air lines to the run the locker.
