Brake Drum Sprockets

8 products

Combined brake drum and chain sprocket assemblies from MCS and Samwel — a single component unique to vintage Harleys. Fitment runs across 1930–1978 Big Twin and XL Sportster applications. Restoration-grade parts that integrate rear drum brake and final drive sprocket the way the factory designed them. Essential when keeping a period-correct classic Harley on the road.
