NNBS Gear swap truetrac Need your Help

So Its been a while on here but Im getting ready to do a gear swap the first weekend of the new year on the truck. I'm aware the 2010 nnbs requires a different carrier bearing on the rear, but what about if you swap in a Truetrac? From what I heard the 2010 has a bigger od outer race but I am trying to confirm. I'm 4x4 so this is the current list Yukon Front and Rear Master install kits for the 2010 newer. Front Carrier (2010 has different deck face so had to by new Yukon carrier), Yukon 8.25ifs spanner tool, Motive 4.88 gears, and a DTL-913A481 truetrac. BTW Decided to go with Gears on the truck since instead of a turbo setup. I need it to tow a little easier and just more "work" then play. The truck should run pretty good with a 33 tire and that steep of a gear ratio calc says 2400 rpm at 70 which is about as fast I go anymore. I may throw some N20 on it but have pretty much met my goal for the truck and will be picking up a datsun Z from a friend in the spring. The Z will be getting a boosted LS engine so I will need something to tow it home when I push it to hard.

I always recommend replacing all the bearings when i did gears, i really don't know if the bearing race is bigger, however, calling the dealer could clear that up. I've had to do that with new jeeps that i put gears in. Even had to get specific bearings from the dealer. You could also call Randy's ring and pinion. Sometimes their website isn't accurate but talking to them on the phone does wonders, those guys are pretty knowledgeable.

Yea I called them today and they confirmed that the outer pinion race is bigger on the 09+ 8.6 silverados. I already had the right master kit on order and the carrier bearings they include will work with g80, truetrac or detroit locker.
