N-fab for sure over factory running boards.
Cheapest I've seen.
Amazon.com: N-Fab T1064R Nerf Step Bar Wheel To Wheel: Automotive
I've never understood these nfab steps. They look like a tough off-road design with a couple big anchors hanging off the sides waiting to be snagged on everything.
I ended up getting it for $300 shipped from Street Side Auto - but that was a year ago. It looks like 4 Wheel Parts has it at $330 shipped now.
I can speak about OEM boards on a 2014 4 Runner SR5 - part # 00016-89004.
They look nice, but are very narrow. It was not my call. The wife wanted them. Boards look better on a 2WD SR5. My opinion.
Nerf bars are better for people who are less concerned with appearance and more with function. My opinion.
Well, this worked for me and should work for you. I found the best price on Nfabs at Streetside Auto.com for $291.06:
N-Fab Part No. T1064R - Wheel To Wheel Nerf/Step Bars (Wheel to Wheel)
I then went to 4WP's webpage and submitted a price match and I recieved a call the next day saying they'd price match the $291 and have NFab send the steps to my local 4WP store for pick up. So...if you have a local 4WP store do the price match for a killer deal on these steps.
Nope
Eff!! They won't? if that's the case I better cancel my order...are you sure?
edit: I just googled this part number and numerous online retail sites are saying they DO fit.
