Wondering if anyone knows any information about converting from drum to disks. I have a 2013 Silverado W/T and i can’t find any conversion kits for the rear.

 

You could do it, but when Chevy went back to drum brakes in the rear they increased the disk size on the front, which does 75 percent or more of the braking. It would not at all be cheap to do so either. Were I you I'd just buy the best brake shoes you can get and forget about it.
