yea a limited slip or possi traction in a truck or car can spin opposite, but not lockers just can't do it, as for the strain it is very very tough on the whole drivetrain , transfer cases also have a tendency to fail in these trucks,also tire wear big time !!, and they ain't cheap, with that said i want a set so bad it hurts, one needs to understand the truck and what will happen to it if it is not driven with common sense, like if some one "like said above"
is going to do mostly paved roads, it is a terrible thing to do to a truck, but alot of things have to be taken into consideration, the coolness factor is super cool alone. as alot of us here i use my trucks and would get alot out of a set, want to do my deuce first, i want the air lockers out there for the deuce, someone here, was in contact with me and i may have missed my chance, hoping though, GREAT to see the 900 going so well, it is truly an incredible truck!! ALL the BEST!!!!!...Randy
