My shocks do a better job managing fast wheel & axle dynamics than the stock front sway bar. An advantage of Currie's rear bar is greater travel arc, and no hoop to get in the way. It is not very stiff. If I had the money I would have installed a GenRight rear bar, which is stiff. Hellwig's bar is an okay alternative.
The Jeep engineers chose a stiff front swaybar, to keep the rear wheels planted while cornering in the wet, and create understeer. Much of the general population thinks understeer is somehow safer. My concept of balance is on the oversteer side of neutral.
