This heavy-duty brake drum is manufactured from premium grey cast iron. The black anti-rust paint provides reliable outer corrosion protection during storage and transit. The inner friction surface is precisely machined to deliver consistent friction, stable braking performance and strong resistance to thermal cracking under heavy load and frequent braking. It is widely compatible with semi-trailer and heavy commercial truck axles. We accept custom production based on OE numbers, samples or drawings, and support custom marking and packaging.
