I just ordered a full front and rear re-gear and master install kit from ECGS a few months back. If you have any questions (I had a lot as it's really confusing) their customer support is extremely helpful. If you can pull them yourself and you don't have a local shop that is recommended you can ship in your core, ask what gears you want and they ship it back ready to install. Top notch.
Great to hear that! I am not sure yet if I will pull them or not, but if I do, that’s about all I will do
