A quick note which may be obvious to some, but wasn't to me...

These shocks, which replace the CATS adaptive damping front shocks on some models, come with an incorrect nut (at least, on my 2002 XKR it was not correct.) So if you order these replacements, I recommend using the old nuts when reassembling. The nuts provided by Bilstein will bottom out on the TOP of the stem, so you must retain the correct / longer nuts in order to properly secure these CATS replacements. It's something that doesn't become obvious until it's assembled on the car, and clunking like mad
