Mine is a combination of sorts - the rear is as Superlift designed it with the SSR remote res shocks. A bit overkill on those but they work beautifully. The front is Superlift with coils made by Deaver Suspension in Santa Ana, CA. The stock coils couldn't hack the weight of a steel bumper and winch and have been retired to a corner of my garage. The Deaver coils brought the sagging front up 2"+ and still give a fantastic ride and the XK sits right about level. Also have Bilstein struts but didn't really notice much difference over the OEM struts to be honest. May go with OME struts next time around.
