VS SS Diff Diffrent to VS S Diff??

[NV-MY-VS]

Hi all,
Just trying to find out if the VS SS Commodore Differentials (Live Axle) are stronger than the V6 ones and if so could I rebuild a V6 one with the V8 internals and billet axles?
Thanks heaps,
Shane

I believe VS SS's came standard with irs

[VL-EXEC]

so did the s (or mine did anyway)

[bandidoben]

s pacs did not come standard with irs it was an option the only models that came stock with irs were statesman and up. untill the VT then it was introduced into the whole range.

ss was option senator was optioned etc.

[bandit10]

SS was standard with IRS so were Calais, Acclaim, clubsport, senator and statesman

So who is right out of all these different answers?

[crackles23]

They were all right out of this post -
SS/Manta Standard with IRS
S Pack Optional
An S pack is an executive with a body kit, they had the same options, however came out standard with live axle.

that would be me
People who dont know for sure shouldnt answer the questions with incorrect answers

The only ones with standard IRS were the ones i listed above, the rest were optional

+1 for bandit10. Have a look here too Holden VS Commodore / Calais

In the mean time, if anyone has actually read the first post, I'm sure the OP was asking about diff internals, not whether he could bolt a complete diff from one car into another.

[Not_An_Abba_Fan]

He said the VS SS had a live axle....it doesn't, so he can't do what he wants to do anyway. Except of course if it was a ute.

Are diff gears etc... the same between the two? I thought that the only difference (between the 8 and 6) was that the the 8 had shot peened gears. Didn't all of the diffs (except for the LSDs) use a 4 spider BW78 setup? Is there any difference between the two internally?

[Not_An_Abba_Fan]

Ummm...yes...the internals are the same, BW78 diff centres are the same whether it is IRS or live axle.

But his original question is still incorrect.

[NV-MY-VS]

Thank-you everyone. I had been told that VS SS came with a choice of either live axle or irs. and wanted to know if it was possible to rebuild my live axle to ss specs?? wether it be by bolting on a live axle straight from an ss or if i could get internals from an irs but i doubt that would be possible.

[bandit10]

SS were all IRS, no live axles SS

This is the the correct answer. IRS came STANDARD on all of these sedan models.
