I thought I would post this info to this particular thread as it seems to be most relevant. I had been doing quite a bit of research, aka, googling, various running boards for my 2014 SR5. I really liked the Trail version, but never could get a definitive answer if they would fit on an SR5. Well, they do. Like a champ!
I bought these 4Runner TE OEM running boards from
Amazon, model number PT938-89100. The description states they are for a Trail model only, but from what I determined, that pertains to year 2011-2013. The 2014 SR5 doesn't have the lower skirt like the 2013 and earlier.
They are a direct bolt on installation. There are six - 12mm bolts already there, but the RBs come with six -13mm replacement bolts that are coated in anti-seize. It took less than 30 minutes for the install.
Here are pictures of before and after.
