The Electrac is a selectable locker, not a limited slip. You turn it on or off with a cab-mounted switch like an ARB. Switched off you have a fully open diff, no different than stock in either 2wd or 4wd. Switched on your front wheels will be locked together and your steering/handling will suffer but the traction will be incredible. Let us know how it works out. What are you running in the rear?
