This brake drum is made of high-quality cast iron or alloy materials. These materials undergo strict selection and testing, possessing excellent strength and wear resistance. During the braking process, the brake drum needs to withstand tremendous frictional forces and heat. High-quality materials ensure that it does not easily deform or crack during long-term use, effectively resisting wear and extending service life. At the same time, the good thermal conductivity of the materials helps to quickly dissipate heat generated during braking, maintaining the stability of the brake system. Specifically designed and manufactured to meet OE fitments and structures, complies with SAE3000 and/or SAE3500 gray cast iron standards, tested in the laboratory and on the road. Specifications: Customizable.
