don't you need limiting straps anyway to protect your shocks from topping out? don't think they would help at all with your problem but you do need them to stop the articulation an inch or two before your shock is at full extension so it doesn't eventually get damaged....just try the antirock bar in the back first and see how it goes....another bandaide to your problem would be to hook up a little fourwheeler winch to the middle of your axle and whenever you got in one of those hairy off camber situations just cinch your suspension down so it can't move...
