if your thinking about this lift i would personally not recommend it if your planning on offroading the kit out of the box is no better then stock for travel as it uses the stock struts in the front and by the time you add new upper arms and coil overs you into the lift another $1500 to have it useable off road. I would look into the Icon coil overs with the TC upper arms or a PRG kit either 3in lift and arms or a titan swap.
If you are looking for a lift kit that is good for daily driving and decent off-road, this is a good choice. People make the kit sound like you will either break it or get stuck by driving on a gravel road. I have had the kit for 2 years and I have never had a problem with it. And yes, I off-road all the time.
