shoundn't these have a taper in thickness of arm itself? not just for the tre's, or are these what i need to put 2wd box w/crossover and hi-steer?

Yes the arm should be tapered as well as the holes

 

[muddybuddy]

u dont need the taper, but the taper reduces stress on the tre's by reducing the operating angle

so the more lift i have, the more important the taper becomes?
