Quaife in a 520 trans?

[inplansight]

I think this should work as the 568 and 520 are common by design but I am not sure and wanted to ask before I get past the thinking out loud stage, so will a Quaife fit and work inside a 520 trans if not why?

Thanks, Paul

This fits A520/A523/A543 just fine.

This will fit A555/A568.

The LSD does not include the actual ring and pinion, and the A555 and A520 ring gear bolts on differently, so you would need the ring and pinion out of a similar year A555 to put a quaife in a A520.

On the other hand, the OBX diff will bolt right into an A520

The ring gear and carrier bolt pattern and bolt size are different for the 555/568 trannys. They take a separate Quaife QDF16B I believe. The Neon (non SRT4) 420A Quaife is probably the one that will fit the 520. That is part # QDF3I I believe. They also go by a # part # as well. That is what the OBX knockoff is designed after. People that build hybrid 555/520 and 568/523 use the OBX more often because it is like 60% cheaper, but the Quaife will also fit. I have a Quaife in a friends 555/520 (350:1 final drive) hybrid in my garage at the moment.

Thanks for the info, that's why I asked before I went down the rabbit hole.
