I'm brand new at all jeeping and 4x4ing in general, but I've been researching KK parts for a while (I just put a deposit on a 2010 KK Renegade but won't be able to buy it until I get home from work in three weeks).
Would the Rocky Road Outfitters external spacer lift ($199) (
http://www.rocky-road.com/kjbudget.html) be what you are looking for lefty?
They also make five lug 1.25" wheel spacers for the KJ (
http://www.rocky-road.com/kjspace.html) but I'm not sure if they match the KK hubs. They are also surprising expensive at $140 a pair.
Reviews seem to say they build good stuff, but have lousy customer service.
*EDIT*
After a little more research, it sounds like they have good parts but
really lousy customer service.
