Outer Limits 4x4 Board

Just wondering if you can get a rear auto locker for a gq... Done some research and getting mixed reviews.. Does any have one on there truck... Im getting arb front but the cost is holding me back to get 2

i have a detroit auto locker in the rear but aparently they have stopped making them. it makes the car marginly harder to drive on the blacktop. but for the money i did prefer my tightened lsd
