rear sway bar?

I bought an Addco setup from Just Suspensions.
Bar is 11/16 inch diameter, largest I could find for my Duster.
Total cost of $89.95 for the kit, tons cheaper than everywhere else for the same kit, albeit with a smaller bar. Also got a front sway bar from them 1 1/16 inch diameter.
These things make one heck of a difference.
