This is true, I have one. I recently replaced all 4 brake rotors and brake pads. I work for an auto parts store and looked up all the parts (as a 2002 Chevy 1500HD
4X4 Crew Cab), purchased them and set to work. Front went together without a problem. Rears however, just weren't going to fit. So, back I went and re-looked everything up (thinking I had screwed up) but nope, computerized catalogue was wrong. I had to look up 2500
pads to get the ones that matched what I took off.
So, it appears that the GM 1500HD's were actually 2500's (right down to the 8 lug hubs and axles, 13 inch rotors and huge brake pads with dual piston calipers front AND rear) with half ton badging. Oh, and it also has a "hydroboost" power brake system. I think the only difference is in the spring rates. Even though I have "looked" at 2500 springs, they "look" the same as my 1500HD. If mine are a little "thinner" or "narrower" then that may be the difference.
The truck "handles" the load superbly, just wish I had more motor at times.
