This will end up being a sticky. After getting in a minor accident they had to replace the rear end which meant the sway bar too. The OEM rear sway bar is back on, and I hate it. Previous to the accident I had the Addco brand sway bar bought off ebay, and Moog end links. New sway bar purchase is in full effect. Two sets exist, a new rear bar, bushings, and replacement front bushings, or a 2 bar kit, for front and rear, replacing both bars with all new bushings. Here is what I have found out so far (price high to low):
They sell a kit for new front and rear apparently "tubular" bars. Comes with new bushings all the way around. Here are some stats:

The thing about this is the easy-access installation page. It is a how to or DIY for any sway bar installation. http://www.hotchkis.net/files/instal...uides/2272.pdf
This kit comes with a new rear bar, rear bushings, and front bushings. No front bar included. The rear bar is 27 mm thick, and it is hollow. This seems to be a very popular package. There are many prices, here are a few.

2004-up Trailblazer, Envoy Sway Bar
1-1/16'' (27mm) Hollow Rear bar This is from Jegs.com item number 515-2272.
Front And Rear Bushings. I know this can be found cheaper, in fact a vendor on this site known as Tbyrne who is currently offering a sale but can always beat the Jegs price price. Also, ebay sells for $229.95, with on average $30.00 in shipping.
Belltech offers a rear bar that is greater in size than average, 29mm thick. This bar is also offered on this site. I believe this bar is also solid. I found this link via drivewire.com: http://www.drivewire.com/percatalog/...WAY%20BAR&pt=4
I believe this can be found cheaper on the trailvoy.com site via a search.
PRICE: US $187.82
The sway bar I originally purchased, The Addco bars are 28mm rear and 31mm front. The rear is solid. It seems any kit that does actually offer a front bar it is hollow, as is the stock one. The ebay solution at this current moment is only a front bar, with bushings(as of 2/10). I believe I paid $130.00 including shipping for my rear bar. If you Message him via ebay he will sell the front and rear bar kit for a discounted price. Ebay ID neverenough2003

Front Bar PRICE: US $129.00 W/ $20.00 Shipping
Overall it is hard to decide, final price shipped to me will make a big factor. The Belltech and the Addco I had seem like good options, I still would want a front bar if I got the Belltech so I would go with Addco. The Eibach kit is nice because they are the same manufacturer and are designed to go together. I think a solid rear bar is the best choice however. New end links are a must for anyone who replaces sway bars. The factory ones just are not designed for larger/stiffer sway bars.
