Thinking about 6" Zone lift kit
 

i am thinking about lifting my 2005 fx4 6 inches and was looking at lift kits. most kits were about 1800 and up. then i came across Zone lift kits online. they were around 1400 for a 6" inch lift. the question is, i have never heard of them before and was wondering if anybody has installed one of their kits and what they thought of them before i purchased one. i wanted to install it myself, does the kit have everything i need? any thoughts on this kit or any other would be appriciated.
