Thx. The Rubicon stickers were a way of reminding me the ultimate (and pretty much unachievable) goal, even though a buddy and I have taken his built Trailblazer (with 33's) and my Envoy (32's) on the easy eastern third of the Rubicon finally. (From Tahoe west to the top of Cadillac Hill and back).
Since 4 Wheeler magazine built, then dragged a Lexus on the Rubicon, I figured I should try to do something similar.
Anyway, there's a Trailblazer and Envoy enthusiast site
www.trailvoy.com, and we hang out in the offroad sub-forum. My user name there is the same as here except with a space in the middle. Every trailblazer owner should be a member there, as the now-orphan platforms age there are a few unique but high-failure rate issues with them. I'm one of the chief technical volunteers on that site for 4WD, suspension, offroad tires, and electrical system questions.
There's no single build thread, unfortunately, since every single mod is agonized over and pre-planned and debated. Only two lift kits out there, but if you visit trailvoy.com and find any post by me, click on my username and the list of mods is in the "about me" section. See ya!
