bed rails

They are generally generic

The rails in my bed fit a Reese hitch I had. I bought a curt hitch and it fit like a glove. I think the rails are standardized for the hitch manufacturers.

My Silverado had rails in the back from an unknown hitch when I bought the truck used. (It only had 26,000 miles on it so he didn't tow much in the two years he had it.)

My Reese slider dropped right in and off we went.

Should be standard, mine were. I just traded in a '06 Dodge dually for a new 2015 RAM. The '06 had a 16k Draw Tight slider in it when we bought it, which we used until last spring when we bought our Suites. I had to up-grade the Draw Tight to something more substantial, ended up buying a Reese 20k hitch off of Craig's list. I called a local shop to make sure the Reese would fit the rails and they told me "should be standard". They were right, the Reese dropped right in!

Now I have the 2015 RAM with the factory fifth wheel prep package so I decided to go with a brand new B & W 25k that drops into the factory puck system.
