Just looked at my sticker again and it could be that my curb weight is less than yours. Mine is 5409

Finally able to have my local dealer install the GM 2" Trail Boss lift and very happy with the outcome. I went back and forth between this one, RC 2" coil overs with 1 inch rear block, and RC 3.5" coil over lift. My service manager (from the GMC dealer who doesn't have much of a dog in the fight) convinced me to stick with the GM lift which was ultimately the deciding factor. That and the fact that I don't need to be in a hurry for new wheels and tires due to looking silly with a big lift and tiny tires.

I have put approximately 150 miles on the truck since the install and it rides great. Noticeably different from stock though - even with the Z71 package. And I am still averaging 23 MPG which seems to be improving as I break the engine in a bit.

Looks great man, perfect stance. I like a little bit of rake, I'm still waiting for Bilstein 5100s to be released for our truck, so I can do my front lift. I'm only planning to do 1-1.5" lift on mine with a 1" rear block.

Thank you. I am really happy with the way it turned out. It's now onto the next few mods.

...and don't rule out the 2" coil over lift if you're planning to add a rear block anyways. If I am not mistaken, most with the 2" RC say that it settles to around 1.5-1.75" which is what you're looking for.

Yah because I'm sticking with the 32" tire, I don't want to go too tall. They're 275/55r20, which are the same height and width as your current tires.
