Can anybody please tell me the sierra xr4x4 diff ratio?

Cheers, Phill

V6 2.8 is 3.62
2.0L DOHC is 3.92
If you can see a VIN plate it will have a code in the Axle box that can identify the diff in that car but always try and get a look at the diff tag

Lots of info on sierra diff ratios here

like snapper said:

any 4x4 V6 (or Cossie 4x4) = 3.62
any 4x4 2.0 Pinto or DOHC = 3.92

(also all the 4x4's should be 7" limited slip with 100mm bolt-on driveshafts)
