Yes the Rear sway bar does make a big difference. The ride feels alot tighter. Especially around big sweeping turns. With my '99 it has a big thick front bar, but the rear was quite small. the rear would lean outside on big turns quite at bit. Now it is minimal. It keeps up with the front end. You will be able to tell the difference I think. But like I have said before if you are looking for street handling. the biggest difference any of my suspension mods have made was the performance tires. It takes that bounce that alot of explorers get over bumps because of the big balloon tires. But if you have a good set of shocks and want to tweek the handling a bit, definetly go with the sway bar. it is probably near twice the size of the stock one, and is a piece of cake to install. There is a definte handling improvement.
Flyguy,
I believe I paid 400 for it installed. I wanted the new one with the indiglo display, but they wanted 600 for that one. I do have a extra antenna, it is on the inside of my windshield. I can push the button in the middle of the mall and that baby will start up most times ;-) I love tha part of it. I guess I will just have to take it back and see what the installer says.
