thanks man. it took me some time to save up for this and save up for that you know but its all well worth it i promise lol. and yea definately get a body lift i am running a 12" FTS now with the 3" body on 41's and i actually miss the old stance my truck had. be sure to throw some pics up of the 6"

 

after reading this i may consider a BL, i have been wanting to go a little bigger, just didnt want to redo the whole suspension.

 

I'll stand by it and argue with anyone who thinks other wise. BL are perfectly fin perfectly safe only exception being a mentally challenged person installs the BL lol. go for it man you only live once and you can't take money with you when you go haha

 

Agreed, go for the body lift.

 

who makes a decent 3 inch BL for a 01 2500 HD long box?

 

With a 6" pro comp lift and some front bumper trimming I was able to fit 37 x 12.5s. I added bushwacker cut-out flairs and was able to fit 38 x 14.5s. With the addition of cut-out flairs alone I don't think you will be able to go from 35s to 38s. You will also probably need to crank the torsion bars or put in a body lift.
