VZ SS Ute
Does anybody know where I can find out the diff ratio for a VZ Ute?
I know this sounds stupid, I have a VZ SS Ute but I don't know the diff ratio (stock) and I cannot seem to find this anywhere......

Help.....

The ratio for a V8 Manual is 3.45:1 in a ute and probably a tonner. There was no option for alternative ratios from the factory. I wanted 3.73:1 and was unable to order this. At least on a 2004 order.

So what to do if you want to change it later? Where does one go, in Sydney that is?

WTF?!?! :confused: . V8 manuals in the VZ's have the 3.73 diff set. It comes like it from factory! Its even in the bloody holden catalogue. I'm at a loss here. You have the 3.73 gear set I bet my left nut on it :D . That was oneof the improvements they made on the manuals, putting a decent set of diff gears in.

ShanghaiVZ instead of your left one how about a carton of Pale Ale :D
The ratios for the ute differ from the sedan with a manual. My ute is 3:45, it is a november build VZ SS and it does have a M6. Before I purchased the ute I checked 4 different M6 VZ SS utes at different locations and every one had a 3:45 in it. It was the way I confirmed it before negoating the purchase. For some unknown reason it is not listed on the holden web site and it is definatly not in the commercial brochure (Wasnt buying a sedan so I havent looked at that one)

Axel I am not from Sydney so im not familiar with any of the diff specalists up there but it should cost no more that $1100-$1200 for new gears drive in-out. I think the gear sets are about $600 from memory any ratio.

MoSkA The Unnoficial Holden Archives might know their **** but they got this wrong. :rofl:

Cheers All

Ummm I don't know what to say now, I'd really like to keep my left nut :whistling :embarrass. The brochure I have is for the sedan which was what my comments were based on. I was mislead alittle. *Goes back and sits in the corner* :embarrass

I have a November 2004 VZ SS ute, the diff ratio as marked on the white label on the off side of the diff is 3.46:1 - I am getting the diff replaced under warranty due to a whine under deceleration (with only 9000k on the clock). I asked the dealer if I could get a 3.73:1 diff as fitted to the Maloo (HSV) but was told that they could only replace it with the same diff. However he did offer to let me get the ratio changed on the replacement diff at my expense by a diff specialist & they would then install it at no cost. I'm not sure if the diff ratio is different on the 05 VZ's but I believe that there was a slight change on the VZ's to the ratio of 6th gear in the M6 box. My old VU SS also had a 3.46.
Anyone out there fitted a 3.9:1 to a VZ ute?
I am interested to find out what revs it will be pulling at 120kmh.

Hi guys, I’m at a loss my 06 vz ss thunder l98 manuel is very decent on take off but want it quicker, on 105km in 5th 2100rpm and 105km in 6th 1500rpm, unless I’m changing into 6th at 130k + it just drones and I feel lose of power, I’m told to go 3:9, what do you think, I want to sort it before my maf tune, think it’s stock besides factory cam and a twin3” xforce, hi flow cats & wildcat extractors, any opinions

it will have 3.45:1 in it now, i'd go 3.7 or 3.9 depending on how much time you spend at 110kph+

So u reckon 3:45, I’m leaning towards 3:9, I’m always on the highway for hours a day to and from work I do 10000k’s every sort of 2 months, I picked my car up after getting exhaust system installed, it sounds so deep now, I’m happy but the acceleration does feel abit flat at low rpm, iv also got to take into account that I’m booked in to Hitorque in December to get a fogger nos wet injection installed, I looked at turbo’s, and my preference is a supercharger but it’s all around 10k, no’s is $3k a comp cam kit is $4000 installed so I went for the nos have to pay a bit extra for them to try and hide it well but hope it’s worth it, do u have any suggestions on what I could do to my l98 ss thunder vz Ute 6-speed
