diff gears

My xf is fitted with 2.72 diff gears and I want to change to a 3.7, 3.9 or even 4.1. Is there another model I could source these from? Should I just buy new? Btw its a 4 pinion lsd.

Re: diff gears

They are available second hand, what engine/trans combo are you running?

Re: diff gears

I'm running a 351w efi with an AOD 4 speed auto. The car is not on the road yet.

Re: diff gears

I will defer to BLWNEB's experience with the slusher. I normally wouldn't go lower than 3.7 with a 5 speed in a V8.

Re: diff gears

Thanks for the suggestions, I might settle on a 3.9. I have read elsewhere that Australian Skylines are fitted with the same b/w diff and have low ratio gears, I will look into it.
