Description:
For sale is a complete set of Jaguar Alcon calipers 6 piston fronts and 4 piston rears. From 07-09 Portfolio edition. Not sure if they fit 2010+ XKs.
They're in pretty good shape with only cosmetic blemishes befitting used parts. Brackets and pad springs included.
They're quite rare and don't see them for sale often, especially a complete set.
$1900
Out of curiosity I checked what these would cost at the dealer and the prices are SHOCKING!
$5000 EACH for the fronts
$1800 each for the rears
$1000+ for brackets and hardware
It would cost over $15k to buy these new. Mind boggling.

Oh! These must be the ones currently listed on eBay, correct? I doubt there are multiple sets for sale in Churchville haha, although I'm just noticing that these don't include the parking calipers as the eBay ones do. Are these also the same ones you had for sale in 2014?
Gotcha. But that is your listing on eBay? You certainly have been fortunate to come by so many of these. I'm in the midst of figuring out what all is needed to put a set on my '08 Super V8, so I'm likely to shoot you an offer as soon as I have that nailed down. At this point I'm suspecting that new knuckles will be required all around, haven't 100% confirmed yet, but Cambo said something to that effect a while back.

I have a 2008 XKR 4.2 (not portfolio) that had these Alcons as an option (I have the build sheet). What sizes are the pistons? If you know, it makes it a lot easier for me than measuring them. As is typical, mine are corroded and I can replace them with stainless steel one’s.
Do your calipers have a coding of ZG or Y on them? That may be the easiest way to determine the sizes.
Thanks for any information you can provide.
