From what I can see in some catalogs, certain Raybestos Pro parts are also sold as ACdelco brand parts.
Carquest has Raybestos Pro, but they also sell Mevotech. If you find a part application and 2 options, the more expensive one is probably Raybestos Pro.
I think Summit Racing has Raybestos Pro parts, but I don't remember.
I have also heard of declining quality of Moog, so I use them only when I:
Can't get an OEM part when the OE part was durable.
Can't get a Raybestos pro part.
