Michael Whitworth Posted December 28, 2017 Share Posted December 28, 2017 Following a thread started by Wizzer I am weighing up my options, Has anyone got a sierra diff for sale that already has an LSD fitted. Also has anyone got an empty diff case I could buy or borrow as a template when modding my chassis to suit this diff. Regards, Mike Link to comment Share on other sites More sharing options...
Robo Posted December 29, 2017 Share Posted December 29, 2017 Mike what ratio are you after ?? 3.6 3.9 ???? Link to comment Share on other sites More sharing options...
Michael Whitworth Posted December 29, 2017 Author Share Posted December 29, 2017 I currently have 3.54 so wouldn't want to stray too far off this but 3.62 seems to be the common one for Sierras So I guess that would be OK. Link to comment Share on other sites More sharing options...

Michael Whitworth Posted December 29, 2017 Author Share Posted December 29, 2017 As I use the car for track days and I don't Need to be quickest off the mark, I am not to worried about Bottom end. So a 3.62 should be OK. What LSD is fitted and what sort of money are you looking for. Also what would you want for the empty case? PM me if you prefer.
