Hi:
I resently installed a lift kit from Automotive Customizers,
http://www.4x4parts.com
Most of the components are RANCHO. The shocks are Rancho 9000's, the leaf spring parts are Rancho add-a-leaf. Check A/C website, they have different packages.
I do like it a lot, I dont have the ARB winch bumper yet, but I still noticed an improvement in ride quality and height. I gained about 3" in height.
Spencer Low Racing have a great lift kit, a bit more expensive, but with great components.
Enjoy your X!
