2009-2018 Dodge Ram 1500 Regular Cab(Incl. 19-20 Ram 1500 Classic) \ 2010-2021 Dodge Ram 2500/3500/4500/5500 Regular Cab|6.5 ft Bed 6061 Aircraft Aluminum Black finishing 6 Inch Wheel to Wheel

I bought the 6" iboards because I love the look and they're aluminum so won't rust. I was a little worried about the strength of them as these are wheel to wheel and wasn't sure how much cantilever the boards would have behind the rearmost support. But APS has a great design and the rear support is perfectly located for a strong step up into the bed. My boards came with the body mount kit and it worked perfectly. There was a little bit of a height difference between the rearmost support that mounted on the bed area and the other 3 supports that mounted on the cab area, but it was easy to tweak with some additional shims. It would have been nice if a selection of additional shims came with the hardware, but it was no big deal. Prior to these I had N-Fab nerf bars on the truck with hoop steps. I realized now that the height of the stepping surface on these boards is higher than the stepping surface of the N-fabs steps. Its fine for my truck, and gives me more ground clearance, but can see for a higher truck maybe the step would be too high to be useful. Overall, I really like these running boards

Was a little overwhelmed by 10 pages of installation sheets till I laid all the parts out looked over the instructions. I wasn't looking to do it as fast as possible I was looking to get it on my truck probably the first time took about 3 hours. Full length running boards should have done that a long time ago. Easy access to the things in the front of my truck bed without getting in it.
