VN diff ratios - Aussie V8 | Holden - Ford

CK_318 · 20-12-2006, 07:43 PM

hello all. there is a guy on the Mopar Market Forum who has
offered me a sway for his Nissan borg warner 3.7 diff for a trade of my 3.45 (if my diff is 3.45). so my question is wot diff ratio did a standard VN Executive come with and are they BW or Salisbury?
i'm only asking coz i can't fit under my car to have a look to see wot it is, and i don't think we have any car ramps lying around anywhere. My second question is also would this be a decent trade if it wiil go in my car?
any info would be appreciated.

as far as i know you have a 3.08 what type i don't know

CK_318 · 20-12-2006, 08:53 PM

i know its and open center, but thats all i know

Standard VN exec will be open BW 3.08 centre. It will also be a 28 spline centre whereas the Skyline one is a 3.7 25 spline centre. The gear ratios will swap over. Always keep the pinion gear and crown wheel as a pair.

The 3.45 ratio came in some falcon utes and Vl wagons (drum rear). Usually there is a tag on teh back of teh diff housing to tell you the ratio but if it has been touched during its life this is not guaranteed to be 100% accurant or even still there. The only other car that came with the 3.45 ratio is teh VL turbos.

Cheers
