a little bit more if i'm not mistaken, maybe 3-400$ more in parts. Camburg 5.5 kit is 1650$ for parts.
Fabtech 5.5 is 1200$
I honestly know for a fact the camburg kit will give you not only
1) a better ride quality with their state of the art geometry setup, but 2 you will be getting so much better of a product for the 400$ more.
