Gear swap on 2010 newer question.
I saw this information on another forum but was hoping someone here could confirm for me?
Starting in 2010, 1/2 ton Silverado's will only take up to a 3:42 without needing a new carrier. They changed the deck height on the carrier and it now requires an new carrier for anything above 3:42. The other issue is that the rear pinion carrier has changed a bit. The ID on the pinion bearings are the same, but both outer races are much bigger on mine than on the older models. They are super proud of the bearings to the tune of about $150 for the pair.
