The tigerz11 12000lb 2 speed and the 10000lb competition winch does not fit on the standard nissan steel bar nor the ARB one. The motor side of the winch is too long (due to the electric brake system I think). The winch has to sit above (not between) the chassis for them to fit. The single speed 12000kb is fine.id check out those tiger11 12000b 2 speed winches..
and id get it with a steel cable, not synthetic rope.
just my preference as the cable would far out live the synthetic rope if its just an 'insurance gismo'
ive not heeard a negative comment about them.
