Don't waste your money , it's not worth it !
A good set of shocks and springs will do you just as good , if not better and will not hinder your lift choices if you ever decide to do that.
It would be so expensive not to mention a major PIA.
I have it and its alright , but it came std. on my 06 sport so I did not have a choice , would I have ordered one with it knowing what I know now about aftermarket shocks and springs .... ? NO !
I feel it does improve on/off road driving , but a stellar improvement .....NO !
