That is incorrect. The Toyota factory rails are stronger. I hate to say that but it is true. I put a set of the Toyota Rails on my 4th Gen 4Runner.ARB makes the Toyota rock rails. Look at the top of this page on the left. THats them in black.
No....ARB does not make the Toyota Rock Rails.ARB is the one contracted to make the Toyota Rock Rails, right? That is what ARB and the Dealer told me.
