So I'm about to swap my cam phasers but am baffled by the large price differences. Amazon has some for under $200 for the pair but then a note that says if you buy from "xyz company" they are counterfeit.

I don't want to have to redo this in a year or two and don't wanna get price gouged. What have y'all found on what brands to buy?

 

Get Ford OEM phasers. all others are junk. I believe Fairway Ford has the best prices.

 

Exactly.

Also recommend you change your timing chain tensioners:

These are OEM steel bodies instead of the plastic bodies you have now. They also have a ratchet that keeps tension on your tensioner arms even when oil pressure drops.
