I like the idea - not sure I'd want that one if, as the listing claims, it was tested until it broke the gears! :lol:
Seriously, I will be watching these with interest. They have the potential to be a lot less hassle than an air locker and a good deal cheaper. I don't like the Detroit Lockers as I want my diffs to be completely open on the road for predictable handling, but I'd quite like a rear axle locker.
