Got it... I have built my own for several trucks and installed them. (I work in a engineering / machining shop.) There is alot to them.
For daily driver and very light wheeling I haven't alot of problem with them.
I have / will always recommend a suspension lift vs. a body lift for the safety and durability.
If your going to build it then please do your homework and don't scrimp on anything. Lastly pay very close attention to the steering column.
In the lift you are sugesting the column will need to be moved down or a spacer / lift joint added to it. Otherwise there will be to much stress on it and there will be failure at its weakest point. (steering box, steering box mounts, rag joint, compression joint, etc....
