I did a search bout could not find anything on my question. Can I run the Fabtech 3" Spindle lift and use the green keys to get a honest 4" out of my 2wd CC 2500HD Duramax? Not looking to break the bank on my lift but i wanted your opinions first. I am looking to run 18"x9" with 325/60/18 Nitto terra grapplers. Thanks for the input.

Fabtech only makes a 6" and/or 8" lift kit for the 2500HD
