I'm speculating that Dodge/RAM/FIAT (my sister-in-law always corrects me if I say Dodge) offers something similar to GM. (I'm stuck in the past, I also call Nissans Datsun).
I put a set of what GM calls work truck running boards on mine. They were all black, which matched my new(a year ago) truck which is gray and has no chrome except the wheels. They run the length of the cab. The step is very solid, the surface is a texture that is very non-slip, and they bolt to existing mounting locations with no adapters.
They also cost less than many of the cheap aftermarket steps.
