35" tires can break parts in Dana 44s, let alone Dana 30s. Nothing is indestructible. 35 inches is a lot of tire and the Dana 30 is a small axle, but if you get shafts that run 297 or 760 'joints and leave the front open it should be fine. Of course, longevity is also dependent on the tires you get, the terrain you travel, and how much you like the skinny pedal. If you want to run big tires, expect to pay for it somewhere.
