I didn't get a kit, too picky for kits. Specs are in 1st post. I wanted to do it once and if its not overkill, you're doing it wrong :-) If you do order from PRG, its worth it to call greg, he will set you up with what you need and discount the prices since we are close and shipping isn't as much for him. He even threw in 3* shims and camber bolts for free.
If you need help on install or want to ride in my truck to see how it handles let me know. I'm happy to help.
