You need heavier duty coils and shocks. I just added a stubby and synthetic line 8k# winch and haven't felt a difference - the front dropped by less than 1/4". I'm running the TF 2.5" coil lift. I'm sure it'll sag a little with time, but I may just add some 3/4" poly spacers to the coils and be done with it.
If you have a 2-door X or Sport model, try installing some unlimited Rubicon springs and shocks. You should be able to find them from a take-off on the for sale or free forums.
