I wouldn't recommend that anyone run on the road without a front swaybar on an XJ, there are too many morons on the road that you may need to avoid without warning... .....but the rear is useless. If disco's aren't your bag, a great alternative is the Currie Anti-Rock setup. I have several buddies running these on their 5"+ lifted XJ's and they are less firm than a stock bar on the street but make the rig more stabile in the rough and seem to not limit articulation either.......if Currie's pricing seems steep, there are similar, less spendy setups available without their logo on it.
