Actually, these forces are calculated for straight ahead, as in the case of winching or pulling from recovery points on the front of the bumper. And these are very conservative estimates because I included the taps in the front of the horns in the 6", which are nonstructural connections. Realistically, those points will withstan very little, putting the stress on the remaining two bolts.

These numbers are rough, but do reflect the ratios of the two different designs.

EDIT:

You have dismissed these plates as being something that will simply be "cut off" in the event of a body lift. A body lift serves no purpose on my truck, as I plan on clearing 35s without one (like Rondo). So these plates will serve their purpose until I get a different bumper.



Where do you see trimming in this pic?

Ron's rig is proof that you can put 35's on a Fronty or Xterra with little or no trimming. I've seen him totally flex out that suspension with no rubbing.
