Recently I installed running boards on my 2017 Nissan Pathfinder, and the result looks beautiful. The running board I chose has plastic top surface and chrome sides. This is very similar to the OEM Nissan running boards which cost twice as much as this one from Amazon.
The installation time is about 4 hours at a moderate pace. I recommend you organize all the parts first, then sort the front, middle, rear brackets and screws accordingly. Everything went smoothly except for several t-bolts that you need to grind down so it fits the factory holes. Other than that, it’s a pretty easy wrenching job.
