Fifth Wheel Rail Kit Recommendation for 2015 GMC Sierra HD


I have a valley 5th wheel hitch and the base rails. I was wonder if this would be the mounting brackets I need for a 2015 Gmc Duramax?


Expert Reply:

We can't recommend you mix the base rail and bracket kit manufacturers so the best option we have would be an all new fifth wheel rail kit for your 2015 GMC Sierra HD that you can use the Valley hitch with.

For that we have the part # RP50066-58 as a custom fit kit for your truck that also fits the Valley hitches.

I attached an install video for this for you to check out as well.
