If you own an 80 series Toyota Land Cruiser or equivalent 1991-1997 Lexus LX450, this is a popular modification that allows you to manually lock and unlock the center differential. This means you can turn your axle lockers on and off in both high and low range 4wd, plus unlock the center differential lock in low 4wd, as well. It's a rather quick modification, as you can see. Don't forget to subscribe to my channel if you own one of these vehicles...
