2000 caprice diff

[johnvtls1]

I spoke to my mechanic today and he said he doesn’t think he can get a 3.9 but can get a 3.7. How much should it cost? I have been told about $650 + tax for the gears. And about $1200 to rebuild it and fit it. Is there much difference between the 3.9 and 3.7?

Cheers

thats so much money for the gains u get. why not just find a second hand diff? for that money you could get a high stall in and the car will go weight better. i got my 3.7's for $350 from ls1 forum and got them installed for $250. really gotta shop around.

go a 3.7 max, 3.9 or 4.11 will murder your fuel economy (+ your in a stato), and you'll still have reasonable top end.

Cheers for your help guys. Alight I will try and find a second hand 3.7, sounds like it’s the way to go.

is 3.08:1 still a good ratio?
