Hi,

I need to set my speedo up and need to know the ratio of my Sierra 4 x 4 sourced LSD. Any ideas?

Steve,

See the sticky in the Engines & Transmission section of the forum...

if its from a 2 litre 4x4 then its probably a 3.92. if its from a v6 2.8/2.9 then is usually a 3,62

most likely gonna be a 3.62 LSD

Hi, my 7" lsd is from an XR4x4 and is 3.62 - is your tag missing or unreadable?
Regards
Martin

It was from a V6 so I think it must be a 3.62. Not sure about tag though, will have a look. Thanks.

what they all said ^^^

V6 & cossie 4x4 = 3.62

2.0 Pinto & 2.0 8v DOHC = 3.92

unless you've got a weird one

If ur still unsure, you could always check it manually
