Rear Diff locks for a V6 Grand Vitara

[fustercluck40]

G'day.

Just wondering if anyone has installed Rear Diff locks in a GV without changing the diff centres etc.

A number of people have mentioned Detroit Auto Lockers or Lockrights can be fitted. However, when I call the suppliers, they sa No there is nothing made for the GV.

Are they correct ???

I have also heard a rumour that ARB may be making air lockers for the GV... However, there is no time frame on that one.

I have a 1999 V6 Grand Vitara... with ARB OME supension kit fitted and 225/75 R16 BFG Muddies.

If front diff locks can be fitted that would be a bonus.

Can any one help or have any suggestions i.e part numbers, who can fit them etc.

A vitara Airlocker will bolt straight into the rear of your GV.

I had front and rear ARB airlockers in my 03 GV.

[fustercluck40]

That is very interesting.

I have spoken to ARB in the past and they knew nothing about the Vitara air locker bolting into the GV.

Have you got the 4 Cylinder or the V6.. I have a feeling the diffs are differnent in the older models?

[GV_Qld]

V6, things changed in my year 2003.

[fustercluck40]

Are you able to provide more information on what is required.


From experience ARB have told me that the Vitara DIFFS & Grand VITARA Diffs are different. Ithink the GV diffs are slightly larger in the rear.

this happened in 2003. what i did for mine was get a complete rear vitara 3rd with 5.125 R/P and set the rear airlocker up in this. for the front i changed to the 5.125 R/P with airlocker in the GV steel housing. you'll also need a vitara inner axle and a stub axle.

ARB know all about this, i've seen it in their install book. when i was first looking at doing it, they didn't really want to do it and sent me to someone else. I ended up working it out myself and installing them.

We are looking at getting in some LSD through Calmini
But it says not for V6 model, GV_QLD how many bolt is the stock rear 10 or 12?

[fustercluck40]

Thanks for the information.

I had an idea you needed to change the diff centres etc.



It sounds complicated if you have to rely on mechanics to do the job as I do.

As I have a V6, the Calmini LSD will not fit..
Anyway, I will kleep looking.

Have you tried Suzuki Australia? I know Suzuki NZ had LSD's for some models listed in their accessory list awhile back. They had part numbers and pricing too, think it was in a pdf I found online.

they are 12 bolt, just remember in 2003 they changed the center and ring gear to a larger size.

the rear is easy for pre 03 GV's any vitara locker should work.

why? the diff is the same between the v6 and the 4.

Be about AUD$852 + shipping after conversion and deducting the 12.5% GST for exporting.

Wonder what Suzuki Australia wants for them?
Part # 27400-65810
Part # 27400-65820

[RIKSTR]

We are looking about $650-$700
As a Calmini part.
Still dont know why they say it doesnt fit a V6.

[fustercluck40]

Yeah... Looked at the Calmini LSD diffs...
However, they specifically said they do not fitt the V6's..

Bummer.

Aprt from changing the diffs, does anyone no if there is a locker etc out there that will bolty straight into a V6 GV ???

[GV_Qld]

A ARB airlocker will bolt straight into your model rear diff

[fustercluck40]

Spoke to ARB in Richmond.

To my supprise, they can fit an airlocker to my rear diff on the GV.
However, he did say that some models may require a vitara 3rd member (what ever that is).

Is there an easy way to tell if I need additional parts etc ??

ANyway, sounds promising...
He also mentioned they have a new compressor (only for lockers)...
Has anyone had any dealing with this ???

I already have a portable Big Read tyre compressor so I do not need another one.

[GV_Qld]

yes, your 99 GV will not need the Vitara 3rd.

[fustercluck40]

yes, your 99 GV will not need the Vitara 3rd.

So as I understand this, The Airlocker will bolt straight in to the rear diff without any additional parts (may require bearings though )

Am I correct ??

[GV_Qld]

yep.

Anybody fitted a rear locker to a GV or 2.0 V6 Vit and kept the original R&P, particularly a 4.875?

[Charlie]

That would be 4.625 for the older V6

[cj]

4.625 for the manual and 4.875 for the auto

[Charlie]

I havn't followed a lot of these threads lately,what are you building?

[cj]

Trying to find a 4.875 to fit a rear airlocker to go in a GV. The I.D. of the GV ring is smaller than the normal Vit rear and the offset is different too. Thought an earlier one from a 2.0 V6 or 4 cyl auto Vit would do it but I heard today that all the 4.875 rear R&P's are different and am trying to confirm this. The size needed has a 118mm I.D like the normal Vit rear instead of 108mm.
