The only negative thing i heard about Teraflex LK is that if you go with an aftermarket heavy bumper and winch, at some point you will notice slight sagging of the front \.It happened to two of the guys i know who had the kit. It does no mean Teraflex is bad it means what stress are you intent to put it under.
If i were you i would go with EVO leveling kit and plush ride springs. Yes the cost is greater but you get what you pay for even if you have no intention to stress the components it pays off in the long run. Again this is my opinion and this is what i would do. Good luck once again !
