spring flip rear is easiest thing to do....that should get you 3 or 4 inches. a set of blocks after that will get you lower.

Front though...I have no idea.

Are you dealing with 2wd or 4wd truck?

For the 4wd truck, the most you can go is 3/5 drop. I have a DJM 3/5 drop on my 2005 2500HD. You can only go 3" in the front because of the CV angles and 4wd components.

For the 2wd, the next step past a 3/5 would be a 6/8 drop.

Manufacturers for either kit would be DJM, McGaughys, Belltech.

I like my DJM kit. I would have preferred to go with McGaughy spindles up front by you have to run 17" wheels.

On the rear of my truck, I'm running the DJM shackles & spring hangers. I've also removed one of the spring out of the pack. I'd like to remove the overload because I have bags to compensate. I built and installed a C-Notch for the rear because it allows more travel and a spot for the airbag.

I have the DJM 6/8 on my '08 2500 HD. I also added front keys to add a little more rake. The DJM kit is good, not perfect.

Dude your truck looks great. I have wanted a lowered duramax for a long time. I think it will be my next truck,.

Thanks for that. I like the looks of those trucks a lot better lowered. Too much wheel well.
