I am new to the diesel world. I have had a 2004 2500hd 6.0 for a few years and i wanted to upgrade. I reacently bought a 2009 LMM z71 4 door long wheel base and i would like to spruce it up a little. Lift, tires, and a hell of a lot of engine work. Can anyone put me in the right direction to making a beast on and off the road?
