I know another brand called owens products. They made 4 different style of running boards for 2010-11 4runner.
I ordered the ABS molded with chrome trim, you can also make it painted to match your turck.This running board is a little bit shorter than the rocker panel, try a set of husky mud guard will make them fit perfectly.
I have both husky and rallyarmor mud guard, it seems like husky will fit better
