Now this might be the best place to ask, but there is no better place.

How much articulation does a stock 2008 get? front? rear?

Will it increase, stay the same or get worse with a spacer lift? front? rear?

With a 4" coil lift, JBA's front? rear?

JBA's 4" is made for 02-07 KJs. I don't know that it would work for an 08 KK.

As for articulation, a spacer won't increase it any. Not exactly sure what the wheel travel is on a KK. Seems like I remember it being somewhere in the 6-8" range. If you get longer coils, the extra coil length will increase wheel travel but, the limiting factor will be your brake lines very quickly. Whatever you add to spring height needs to be added to your bumpstops as well so you can't actually get the full length added to your articulation. You will get more down travel (as long as your brake lines will permit, anyway) which will help keep your tires on the ground.
