Anyone heard/had any issues passing safety inspections with these aftermarket a -arms? Are they certified for on road use?
I don't think many parts are regulated by any sort of governing body. Besides lighting [DOT], safety components [DOT?], tires [DOT]..I can't think of much else...except emissions components [EPA].
Consider all the modified 4x4's for a second, there are hundreds of thousands of them throughout the states with aftermarket control arms, tie rods, drag links...even some that are completely home-brewed that go through inspections without hesitation.
