I don't own these, but looking at the website pictures, it seems possible to remove the protective end cap on the steps, cut an inch to inch-and-a-half from each end and replace the end caps.
The steps are aluminum, so cutting on a chop/miter saw should only take a minute or two (use a high tpi blade). Deburr the cut edges, and should be good to go.
Remove a bit of the fender flares to make the steps fit.
If I had these steps, I'd cut the aluminum vs. cut the fender flares.
Hope this helps.
