I bought some Raybestos drums for a 54 GMC and a 56 Ford Passenger car. They are all made in China.
I will not install any more Chinese drums on my semis. I bought a pallet of them from International with International part numbers. About 25% of them broke to pieces which is not only a dangerous situation, but also a DOT out of service. I don't need points on my CSA 2010, nor do I need to pay tow charges for red flagged vehicles. Fleetpride made me a deal on 6 pallets of Centrifuse drums. They cost 3 times as much as the Chinese junk, but we haven't had a single failure. And we are hard on brakes. Grossing 84,000 on 5 axles and a lot of stopping in the metropolitan San Antonio area traffic.
I would strongly consider used drums. These guys cut a lot of old 3/4 ton pickups.
