I just replaced the chrome with black on my 2015 SLT Crew cab. The parts numbers have recently changed. The numbers I have from the parts I obtained and are now on my truck are
Front Belt moldings 23227165 and 23227166
Rear Belt Moldings 23227174 and 23227175
Please check these numbers in case Ive mis-typed any thing. All 4 moldings came with the plastic clips attached and in substantial cardboard tubes.
I found the most useful tool to release the clips on the moldings that came on the vehicle was a putty knife with a 1" wide blade. It is the same width as the clips and prys (?) both 'hooks' on each clip at the same time.
