Hey guys, thanks for the replies. Sorry I dropped off the face of the earth on this one, been on vacation with the family. Called Les Schwab and they told me they could only install a two inch in the front, nothing in the back, without having to change stock parts such as the shocks and things. Sound legit? I thought I'd seen 2.5 in front and 1 in in the rear without changing stock parts. They'd quoted either a tuff country/rough country. Cant remember which. Basically a C shaped spacer in the front.
oh, and I believe it's an early 07, as it was built in 06.
