If you believe the haters, I anything I might have to say regarding TeraFlex shouldn't be listened to due to my friendship with EVO. But, if you are willing to hear what I have to say, I will back it up with proof.
Regarding their long arm kit, it will get the job done but, their brackets will still hang lower than the frame rails and I have seen them break off on more than one occasion. While some of the breaks may be caused by installer error, most of the ones I have seen were not. Here's a link to a recent break I saw:

And, if you contact the member highoctane, I'm sure he'll be more than happy to share his experience with you as well.
What I will say is that IF you plan on running coil overs, this is definitely not a kit that I would recommend as the joints will not be able to handle really big flex. I can't tell you how many blown out bushings I have personally replaced/repaired out on the trail because of this.
