If you just want to level the truck, no high lift, like I did, the Bilstein 5100s are the way to go. You retain complete shock and suspension travel as compared to other methods. Plus the great Bilstein ride. See the pdf from the bilstein site for a load of info on the other methods and their short comings. No damage to your suspension. Just saying...http://www.bilsteinu..._WebArticle.pdfhttp://www.bilsteinu...ght-adjustable/
The first day on my 09 I put the Michelins on and then true and high speed balance on the truck. Them I added the Bilstein 5100s around which leveled the truck. Really made the ride and everyone that rides in my 09, CC, 4wdr z71 says the ride is the best they have seen in a truck (and they drive ford, GM and toy trks).
With the stiffer frame and heavier anti roll bars the new trks should really take to the setup.
