i was wondering if with a 6" suspension lift if it would be unsafe and prone to roll over to add a 3 or 2" body lift?

 

No more prone then it is now. I find these trucks pretty stable off-road. The lift kit and body lift will raise your center of gravity and cause the truck to be more prone to rolling over, however to combat that you just need to slow down some. Not like your planning on doing high speed manuvers or anything are you? Plus you could gain back some of that stability by going with wider tires, and/or changing the backspacing on your wheels. Push them out further will give you a wider track and more stability. With that kind of lift you could run 33/12.5R15 tires on 15x8" wheels with a nuetral offset and be fine. Might have some clearance issues at full lock and/or full compression, however nothing a little pounding or trimming and fender flares won't fix.

Go for it, and post up pics.
