It's just so weird why they don't list this LSD for E53 3.0 Auto. I emailed Quaifie.

E53 X5 3.0i manual rear diff; 4.4i auto rear diff; 4.6is auto rear diff
It seems to me the diff type is 188k, the same for manual and auto transmitting
You're definitely blowing it out of the water with this upgrade. Just the LSD and bearing set is over $2500CAD, more than the price of most E53s these days.
I spend more money on my X5 than on my gf but still can't justify the price tag lol!
It looks like there's a cheaper alternative, I'll give it a shot.
