but a 2" would make a great rig.
2" is sufficient but I don't recommend it. I have some threads stripping on the transmission pan due to a few bangs it took, and my oil pan took many hits as well on the infamous topes....I recommend 4 inch lift if you get a Astro, its not much more money anyway.
Also, you can find just about any answer you are looking for in this thread:
