I have a 2003 2500hd 4x4 CC. I want to know if anyone can tell me the part number for the torsion keys i need for my truck to get the the 2" of lift and is anyone running 18x9.5 rims with 6" backspacing with 325/60/18 tires and getting any rubbing or will it rub if offroading is done at all and if no rubbing has the bupper been relocated and how many incheshttp://www.dieselplace.com/forum/smileys/Question.gif Thanks for your help.

Try doing a search and you'll most likely come up with all the information you need.

I have read alot of the forums about the keys and tire size and everyone talks about everything but really doesnt make it clear what kind of set up they have like year and green keys or purple etc...... Edited by: No J.O.B.

Saw this post, didn't know if you are still checking for feedback on this topic or not. The GM Green torsion keys and a slight crank of the torsion bars will get you a little over 2 inches without sacrificing TOO much ride. The issue I think you will have with the 6 in backspacing and the 9.6 in wheel is the same I experience. When turning, you will rub on the rear of the wheel well due to the amount the wheel will stick out of the front of the truck. With a 6 in backspacing on a 9.5 inch wheel you are looking at a +20 offset. I have a similar set of wheels on my truck but with a +19 offset and have 9.5 wheels. My tires are 305s instead of the 325s you are looking at. I do get a slight bit of rubbing when backing up and have the wheel fully cranked. In my opinon, you are going to rub alot with the 325's. Also, to fit the 305's we had to trim the front airdam a bit. No big deal, but it was something you should know. Try and find a more positive of an offset wheel if you want to fit a 325 under there. Good luck, I know several people have done it I just don't know how much rubbing they experience....


Hope it helps.

Se7enracing thanks for your time and input. I'm confused on this back spacing and the + and - offset. From what you said should i go with a rim with less then 6" of back space. I think i will take your advice and go with a smaller tire like 305 or 295 and probally a 18x8 rim because i dont want any rubbing if i try and put it in a bind. Thanks again

You can get the "green keys" from www.gmpartsdirect.com (http://www.gmpartsdirect.com) part number is 15592573, get 2 of them. I installed my keys, got ~2" of lift in the front, and fit H2 take off's on, 315/70/R17. Had to trim the front air dam a bit, and I get a slight rub when the wheel is at full turn, but it look 1000% better IMHO.

CaptainTrips: Thanks for your time and input and the part number. I have been looking into the H2 wheels just not sure yet. I'm really trying not to have any rubbing but want nice big tires and no lift. I just dont think i'm going to be able to have my cake and eat it to. Thanks for your time.

Maybe this sheet will help you understand the backspacing and the width issues you may see...
