I went for the front locker option because of concerns about noise and locking under normal road conditions. I can effectively switch it off when not needed, though it will strain the driveshafts a bit more.

Keen to see how much climbing advantage it will give, hopefully can maintain rear traction with a bit of added flex.

Do I need to source a new pinion nut, or does the gearset come with one?
