Unknown part??

[Ritzace]

Hey guys I have no idea what this part is and where it goes. It’s pretty heavy and seems important. I took it off a while ago and it’s just been sitting. Thanks. Sent from my iPhone using Tapatalk

Looks like #14, the pitch stop. Same as the RWD part I think, but I guess my iX lost its one at some point because it didn't have one.

The iX has a different rubber stop that's mounted onto the front subframe.

The part you're showing it for a RWD model only, I've never seen it before.
