I'm wondering why the drive shaft hangs down so low on this truck? Maybe it's just an optical illusion but these picks make it look like it would be easily damaged by any type of offloading. Is this is referred to as "pinion angle" and what can be done to correct this?

I'm debating on whether to build a 4x4 or a 2wd. If I decide to build a 4x4 I want 33" tires and whatever lift that is needed to accommodate them but I don’t want the driveshaft hanging down like that.

It belongs to a member here named derotoreut. This one does not seem to have the driveshaft hanging so low. Maybe it's just the pics or the lighting or maybe because it’s a short bed I'm not sure but I like how this one does not seem to have the drive shaft hanging down like the 69 in the first link.
