ROAD CHOICE® BRAKE DRUMS are manufactured to meet the toughest requirements of the heavy-duty North American aftermarket based on recommended SAE practices and are covered by a limited warranty for the life of the drum. Every Road Choice full-cast brake rear drum is machine-balanced to 20 in-oz. specifications, with front drums balanced to 10 in-oz specifications, per industry standards. This helps to reduce vibration and improves roll characteristics for a better ride. Bolt holes are machine-drilled to provide tighter mounting tolerances. Available for the most popular front, rear, and trailer positions to meet RSD requirements, Road Choice brake drums provide quality, performance and value.
