9 inch or 8/3/4 lsd for au falcon

Hi ...hope you are well today...Firstly Iwould like to find out where can I get a conversion of my au wagons' diff to maybe 9 inch or 8 inch lsd here in sydney.I also have been advised by some forum members that 3.5 ratio and up would be the go. Please bear in mind that I do quite alot of driving at 110 kph(freeway driving).I had a 3.5 ratio on my old xc falcon and it slowed down from this and revved too much...is the ford 4 speed auto easier revving with this ?

useless, I have a 3.45 LSD in mine and it revs about 100rpm higher at 100kph then the EF wagon I have.
No need to change the actual diff, just the diff center.

The AU wagon has a 3.23 BTR diff in it and you can get 3.45 or 3.73 gears fitted drive in drive out for $900 or $1500 with an lsd centre.

In Sydney try Craft Differentials

$600 extra for an lsd centre what a rip off!!!!!

I rang around a while ago and for full rebuild incl bearings, lsd, new everything on exchange basis was $780 drive in drive out. that was for any ratio. that price was from a place in greenacre from memory.


just fyi, you can get 345 led from pick a part in narellan i think for about $400. disc to disc with around 100k

Re: 9 inch or 8/3/4 lsd for au falcon

id like to know how they can do a NEW diff for 780, on an exchange basis, seing that an LSD Hemisphere is $650, gear sets are $550, and bearings are $200 odd. None of that includes labor.

only telling you what they told me mate...highest quote I got was $1000.

I did fail to mention that price is with you removing the diff from your car and reinstalling it.

Good question, has any member installed 3.73 in an au i6 or v8 4sp auto? Thinking of change ratio in the TE50.
