Webb Wheel’s lightweight brake drums

Webb Wheel’s Steel Shell Brake Drums are engineered to allow for increased payloads. The lighter, stronger design features a one-piece outer shell with a fused cast-iron brake liner. The company currently offers three options for a 16.5-by-7-inch application and is planning two for a 16.5-by-5-inch application and one each for 16.5-by-8.62-inch, 16.5-by-8-inch and 15-by-4-inch applications.
