i have a 1999 trailblazer 250. ive had for a while but the back end of it sets alot lower then the front. is there any why u can adjust that. or do have to buy a new shock?

 

I think the only way to lower the front would be with tire size. If I am not mistaken that front has kinda like a shock strut set up, probably called something else but it is what it looks like on mine anyhow. You could probably drop a couple tire sizes in front, you would lose a little clearence though.
