The gears are plenty strong and the case will be fine as long as you don't smash it on a rock.
To clarify, we are talking about an NP241OR (emphasis on the "OR" in that part number). The NP241OR is the rubicon transfercase that has 4:1 low range. It is a completely different case than a NP241 (not just different gears). If you can find them for $200, you should buy them all. They sell fast around $1,000 from what i've seen.
