I have an 05 2WD STX. I want to level it out I have found a 3 inch, 2 1/2 inch, 2 inch, and 2 3/4 inch. Which one would be the best to get to make it level? and if I put on a 1 1/2 inch rear lifting shackles should i go with the 3 inch?

 

Do what I did be sure and have your truck on flat surface such as concrete and measure straight up the center of wheel to bottom of fender that should give you the height differance and go from there
