Just get the FORD replacement for a 2014.

I can’t find a diagram or Ford part number for that pulley. It would appear that it is an additional one added with the Roush Supercharger Kit.

Try 19A216

I don't see why there would be an additional one. I used the OEM set up when I installed my Roush Stage 2.

That one looks like it does not have enough ribs (too narrow).

This is the pulley I’m looking to replace View attachment 386796

Wow, I've been around here a long time, and this is the first time I have seen a pulley actually used in that spot.
I've never had that pulley when it was stock and now even after the Whipple install.
It doesn't even do anything except create more friction.

Yeah it definitely has me scratching my head. I went ahead and ordered the ROUSH Shield kit which from my understand deletes that pulley.

I'd have to see the belt routing in person, but I assume it provides more belt wrap around the S/C pulley.

My 2013 Stage II had this setup. I think I shared the details in a post from late 2018 or early 2019. In short, a vendor told me to remove the ribbed idler after the truck suffered multiple belt jumps including two of which outright breaking the tensioner arm. After removing the ribbed idler and installing the new belt, 60k+ miles later, no more belt jumping or broken tensioner.

I think that's why it was redesigned on the 2014's.
