RAK,
If your window sticker says you should have one, by all means, take it back to the dealer and show him that you don't have it. Now, they are saying in other forums that Chrysler said that on the 03 Turbo, the rear stabilizer bar is built right into the rear housing. Don't know about the other models, so your dealer might try and tell you that also, but there's no harm in trying. Will the bar help? Depends on the way you drive. If your a little aggressive in your driving, the bar will help in keeping body roll to a minimum in hard cornering and if you travel over a lot of bad roads, it will keep wheel hop down. It's entriely up to you.
