LSD on VT's ?

[ramzisleiman]

hello guys.
All VT's come with LSD diff ?
I live in middle east, mine got an open diff. i don't know if the previous owner made a swap and installed an open diff instead of the LSD. but now i want an LSD.
where can i get one ? Or can i get only the internals and convert mine to lsd ?
what commodore models have the same diff as mine, if i want to buy a used one, will it fit from other models?
thanks in advance.

Pretty sure it comes standard in the Calais.

is it a series 1 or series 2? i know in the V8 ones they had different diffs. 78 series diff in series 1 and 80 series in series 2

the only models were the V8's but they were options on the V6's all including the Super V6, ive got a 9C1 pack and it came with one, its great, if you can get your hands on one you will love it!

the lsd or any other type of diff from, vx on, had a differnt connector to the driveshaft. You can update your drive shaft if you can only find an LSD from a later model.

ebay is a good place to start if you are looking for a second hand one or the internals. I think you may need at least the hi performance or an actual LSD to put in the internals to make it lsd.

the easiest way to tell if it is lsd, will be the tag on the sump plug stating lsd oil only.

I did mine in my supercharged 6, definitely worth it.

here is a link to a site that may give more info on the models and options.

hey if he said to you it has a lsd, it will cost him not you.

but there are heaps of posts on here on how to tell if you have an LSD, most of them are jack up the car and rotate one back wheel and see if the other one spins, in the same direction.

It varies from model to model, series to series.

Any NA v6 came with a 7.5" crown wheel diff.
v8's and the super 6 came with a tougher 8" Crown wheel

As far as I know, only the HSV models came garunteed to have an LSD, although it was a factory option on models.

Standard LSD is a cone type.
