Thoughts on Solid Front Axle Swap on 2007.5 3500 hd

I have been tossing around the idea of doing a SAS on my duramax. I know there are kits to put a ford Dana 60 under the truck. But most of them that I have seen all are for six inches of lift or more. I want to stay as close as possible to stock height. I would not mind two or three inches, I can just stack more leafs in the rear.

I also thought about modifying the Dana 70 front axle out of a Kodiak. But I have never heard of that being done.

I know most people will say it's not worth it. But I have plans for the truck in the future and it involves putting a much heavier engine in it. The stock IFS is soft. It works great for a gas truck that never leave pavement. But my truck sees a lot of time in the field and driving over the berms and though water ways. Even going slow I can feel the front of the truck drop. That is with an 800# duramax. Eventually the truck will get a DT466 or a 3126. Both weight north of 1,400# And I know even with upgrades the IFS will not hold up well.

Has anyone done the SAS. Is it a pretty straightforward swap? Or is it one of these swaps that the little things you need end up taking longer than the actual putting the axle in?
