Stock front rotor on a DRW truck is GM: 12549137, AC Delco: #177-804
What I put on was the rotor that came with those suspension parts off of a 2000 K2500 (GMT-800) and it is GM: 15942195, AC Delco: #177-1038
Stock: 12.5 in x 1.535 in
Current: 12.795 in x 1.5 in
When I need to replace the front brakes I will likely move to the GMT-800 DRW front rotors, P/N's: 15733625/#177-878 which are the exact same dimensions as current. Where they differ is in the thickness of the wear surface, the DRW ones are much thicker. Visually the region of the rotor where the vanes are is half as wide.
