is it worth the extra money for the arb's over detroits? ive got a 60/70HD and the arb's are "only" another $200 or so over the detroits. of course then i gatta do onboard air and such as well. the axles are going under a rig that will see a decent amount of street use and offroad when i get a chance. i was thinkin at least maybe 1 arb and 1 detroit, but if i get onboard air for one, might as well get another. is it worth the extra money, or should i just get the detroits? what would you do? if you say i should get 1 of each, should i get it for the front or rear? thanks guys
