Probably not if they are straight.  Aluminum bars exceed the yield
point when you hit rough road at times and take a sag.  Look around
and you'll see some bars that are no longer straight across the
horizontal.  It is these bars that are just short of failure.  I don't
know whether bars that are in original alignment also break.  The ones
I have seen all had sagged a little.
