Hi I've got an 03 trailblazer with around 180k. I've begun noticing that i lose alot of speed when going up hills. I live in an area where i go over one on my way to work and no matter how much speed i build up (around 60-65) I'm down to 30-35 half way up the hill. Its not even a very large...

So I just bought a 2003 Trailblazer LT 4X4 with the 4.2L, I am here for info on lifting it, and I want to see what all you guys have done to yours.

Ok I'm sure this is going to make me sound stupid, but on my 03 trailblazer theres a small on off switch to the left of the steering wheel near the hood release lever, theres also a little black button above it. I have no idea what it does :crazy: is it for when a trailers attatched? Because...
