Default 2011 4.8l 2wd Rear Drum Brakes 8.5" or 8.6"
2011 Silverado 2wd 4.8l rear drum brakes

Is it a 8.5" ring gear or the 8.6"

Conflicting info on the net.

It doesn't matter, the drum is the same size.

Even if you look on rockauto at AC DELCO parts, there is only 1 option for the rear drums. All the drums are 13.2inches.
