I ordered one from SDtrucksprings.com because they had a screaming deal on them, but the "black friday" specials ended Nov 30. The Big Wig for the back of my '03 2500 Ram ended up being $308 shipped. Retail is $550, their regular price was $422, the sale was $338 and I got $30 more off for using a special code.
Edit: it seems the "sale" has been extended. They DO NOT stock these bars, but rather order them from Hellwig and have them drop shipped. It won't be until late December before mine is shipped.
The codes are found at the top of this page......

If you cannot find the listing, and mine was not listed, find the number on the Hellwig site and search that number on the SDTruck site, it will turn up.
If you are in a hurry and cannot wait, you might try Michigan Truck Spring
https://www.truckspring.com/ as their stock will show up on the web site and they do stock a number of the bars.
Co-worker recently bought a 2005 Surburban 2500 with the 8.1 engine. Been searching for a year. Ordered the sway bar from SDTruck and they called him to tell him it was discontinued. He started searching the net and calling and the second call was to Michigan Truck Spring, they had the kit in stock and it is enroute to him. Funny part was that it was cheaper than the SDTruck price.
