There are other options, you could put
a limited slip diff or a Lock-Rite, the locker
will give the most traction, but is harder to
stear and can break axles and housings.
The limited slip will be normal feeling until
there is slipage, but will not hook up as
tight as a locker and allow easier steering
when needed. Lockers are about $250
Limited slip is about $450 ARB is quite a bit
higher than both, but you can't beat the selection
between open and locked
