I am hopeful that my stock stub shafts will work when I get the diff swapped. If anyone would like to chime in and offer guidance or share their experience, that would be great.

Curious if any SES codes will be thrown when the gears are upgraded. I understand cruise control will be voided. I believe ECU Tek said they can get that back with their tune.

So your diff came without shafts? If it did come with shafts, there is no need to change them out. Anyway there should be no codes thrown after the swap. Also cruise control might work, mine does. Do a flash reset via the tap dance method, then when you start the car turn the cruise button on first before moving the vehicle. This method worked for me & I have never have my cruise not work.
