I originally planned to put this in my 2007 XKR but have since decided to just upgrade to a XKR-S soon.

I live in the Dallas area for any local pickup, I will ship but buyer pays shipping.

I am asking $1100.00 which is $300 below retail and saves you sales taxes as well. The item was NEVER used or installed and is still sealed in its packaging and packing grease.

This LSD info can be found here

Quaife ATB Helical LSD Differential JAGUAR XKR

 

Good price!

This diff fits other models too:

S-Type, up to N52047
X350 XJ, up to H31470
X250 XF, up to R41865
X150 XK/R, up to B32752
Unless the diff on the car was replaced under TSB JTB00175

Good luck with the sale!

 

Thank you for the helpful info, much appreciated.

 

The web site doesn't say it will fit the X150 XK, so you weren't implying XK and XKR, correct? (Tell me I'm wrong, as I'd like to get one for my XK.)

 

Hi, is your Quaife still available. I sent you a private message. Please give me a call, i'm interested.

Thanks,

I contacted Quaife, and they said it should fit both the X150 XK and XKR (guess they figured XKRs could use it more).
I'm interested too, but I suspect it's already sold.

 

Sorry I missed your post.

The diff in the 4.2 X150 XK and XKR is identical, so no surprises there.

The Quaife QDF3W fits a lot more cars than they list, but for whatever reason they never updated their marketing materials....

 

I think you're probably right, she's gone. After searching around on Google, I found this ebay ad, which was posted a few days after madhtrxkr posted it for sale.

I do recall seeing that listing before, but I didn't know it would fit my XK at that time, so I didn't pull the trigger. Maybe that's the one 'flyc2c' got, and used in his excellent DIY thread. If so, it couldn't have gone to a better buyer.

 

Yes I was the one who got it. Very kind thing to say kj. Thanks!
