Diff Gears

[Dinwoodie]

Hey everyone!

Before i get blasted and told to search i have and haven't found what i was looking for!

I have a 5.0L VS Ute and was looking at getting diff gears, as far as i know it is running stock setup! The car runs at about 1750rpm at 100kmph so i'm happy with that, but i didnt want to change it too much as to make it run at 3000rpm at 100kmph but i want it quicker off the line, has anyone run 3.7's i've read on other forums they are pretty good but i know the people here at Justcommodores know more shizzah than the others hence the reason i am asking the question, thanks in advance!

3.7's will put you at around 2500rpm at 100kmph with a 4 speed auto.

what a bout a t5 manual ?

ive got 3.9's in my 5L vs clubby and it sits at 2500rpm doing a 100

im chewing thru 11L/100km sitting at 100 if your interested in fuel at all!!!

what about 3.45's?

[VSIIBerlinaL67]

i have 3.7's and its 2150rpm at 100ks auto

[padrickz88]

3.9's in an auto will be about 2400ish
So 3.7's would probably be about 2250-3000?

I've got an ecotec and a getrag, i'm sitting at about 2250 at 110kph .. as far as i know the diff is stock

Exactly the same here m8.

In auto's stock diff gears mean you get 55kph for every 1000rpm.

So 110 @ 2000, or about 1900 at 100.

2500 for 3.9's at 100 is somewhat ok, I thought it would be worse.

Wicked! I'm now looking at 3.7's it's a good happy medium, do i have to get the speedo changed or will it automatically adjust because it's electronic? If i do have to get it changed who would i see to do that?

Yeah that looks wicked, but it seems to only be sold in a kit, and the last time i tried to get a kit made from jaycar i almost cryed, i couldn't find anyone to do it and jaycar couldnt recommend anyone!

So 3.45's?
