Hey man, I used a 4/7 kit. It's coil relocators, spindles, and a flip kit. I got mine used from a member on a forum but our vendor here Tim can hook you up with a McG kit or if you decided to go Belltech then Kris at our vendor TheSuspensionSource could hook you up. Both are helpful and I would recommend over someone like summit.com. Just tell them from where and who you found them. Hope that helps some.
