Has anyone lifted a 2wd cummins like mine in my sig, i want to go up 4-6" to get a little more clearence, how can i get that much lift, i know that the back will be easy but the front is what i don't know about,

 

I dont see any easy way of doing that. You need to relocate the mounts on your a-arms to get the kind of lift your looking for.

 

I am pretty sure that the best you could hope to do is level out the front end. Unless you build something custom, there isn't much out there in the way of lifts. Check my sig for the easiest way to level yours. Worked great for mine.

 

A body lift will fit, the body mounts are the same as a 4X4. I wouldn't go more than 2" on a body lift, more than that just looks awful.

 

There are also some coil spacers designed for our trucks on ebay for 49.99. I will look again and find the link. These go under the coils. Just type in D250 lift Item number: 120276605597
