I agree w/ Bullfrog that a stabilizer helps quite a bit on almost every JK. As some have posted they may have a combination of suspension setup and tires and vehicle loading where it happens that a stabilizer doesn't make much difference, but in almost all JK's it will help quite a bit. On the fast highway curves and hills in SoCal where all 5 lanes are doing 75-80 replacing my shocks and stabilizer w/ Bilsteins on my stock 11' JKUR made an improvement, if I ever replace the Bilstein stabilizer I'll probably see if the more expensive Fox stabilizer is even better.
