Hey I'm new to the forum, I have 2009 GMC Yukon 4WD. I'm looking to put larger tires on it, either (305-55-20, 295-55-20, 275-60-20) I have the stock 20x9 wheels. The guys at the 4WP store told me that I could level the truck using the Bilstein 5100 shocks and struts (but he said in order to get a 33" tire i really needed to get a 4" suspension lift). I've looked at some of the posts on here and it seems a lot of y'all either have the CCM 2.5"front / 1" rear, or the rough country 2" leveling kit). If anyone can please give me their opinion on what has worked on their trucks (ride quality, trimming, tire size, etc.....) I'd really appreciate the help.
