Wanted Sierra 7" LSD 4:1 or 4:44 diff

HI

As above I am looking to try a different ratio currently running a ATB 3:92 but looking to see if anyone has either a 4:1 or ideally a 4:44 LSD for a sierra 7" push in shafts.

I am open to either a compete diff or just the crown wheel and pinion.


Ideally collection from Midlands or Preston.


Thanks

I don't have a diff.

I'm interested though - which model Sierra's had 4.1 or 4.44 ratio diffs? (I've not heard of those ratio Sierra diffs before)

I think I have a 4.28 non-lsd from a Granada. Push in shafts.

I had a 3.92 by it seemed to sit funny while on track. I had no acceleration in 4th and loads of corners were too fast for 2nd / to slow for 3rd.

The change in ratio really allowed the car to sit in nicer rev bands on track.





Track days ARE the best thing since sliced bread, until I get a supercharger that is!

Hi

Yes thatís what I am finding, even at somewhere like Snetterton I was only just getting 5th certainly seems like thatís the way I need to go
