ABOUT
Our Experts Are the Finest
DONGSAN is a Korean brand born from a commitment to deliver precision, durability, and safety in the automotive aftermarket. Established with the vision of becoming a trusted global name in critical vehicle components, DONGSAN builds on Korea’s legacy of engineering excellence. The brand was created to specialize in high-performance clutch systems, braking components, and cooling system parts, with a particular focus on Clutch Discs, Clutch Covers, Brake Pads, Brake Shoes, Brake Discs, and Engine Thermostats.
Backed by decades of automotive industry experience and strong partnerships in both Korea and abroad, DONGSAN has grown rapidly in reputation among discerning distributors and OEM-level buyers across Asia, the Middle East, and Europe.
DONGSAN’s core engineering and R&D functions are based in South Korea, where product design, prototype development, and quality benchmarks are defined. Our Korean manufacturing base handles premium product lines that require the highest level of precision and material control.
To support large-scale global demand and maintain price competitiveness, selected production lines are established overseas under strict supervision from our Korean engineering team. These facilities follow the same manufacturing protocols and use approved raw materials, ensuring full alignment with DONGSAN’s standards.
Each overseas facility undergoes continuous audits and process validation, maintaining a seamless connection with our Korean technical office for process improvements and technical upgrades.

PRODUCTS

Clutch System
DONGSAN clutch systems are engineered for OE-level precision and durability. The clutch cover is made from high-tensile steel, CNC-machined for accurate fitment, and equipped with high-carbon diaphragm springs that ensure consistent clamping force and long service life. Each unit is dynamically balanced and surface-ground to minimize vibration and ensure smooth engagement. Clutch discs feature hardened spline hubs and friction linings made from Xentar-based , offering excellent heat resistance and torque capacity. Damping springs in the hub reduce drivetrain noise and absorb shock effectively. All components undergo strict testing for balance, load, and endurance, ensuring performance and reliability in demanding conditions.

Brake System
DONGSAN brake components are designed for superior safety, stopping power, and durability. Our brake pads and brake shoes are manufactured in Korea using advanced friction materials such as Metallic, Semi-Metallic, and NAO, ensuring low dust, reduced noise, and excellent heat resistance. Each compound is rigorously tested for fade resistance, wear rate, and braking stability. Our brake discs are made from high-grade cast iron, dynamically balanced, and precision-machined to OE tolerances to guarantee smooth braking and minimal vibration. Surface finish and runout are carefully controlled to ensure even pad wear and extended service life. All products comply with ISO and ECE R90 standards for consistent, dependable performance.

Cooling System
DONGSAN cooling and sensor components are engineered to ensure accurate thermal control and engine protection. Our engine thermostats and thermostat assemblies use high-precision wax elements and stainless steel springs, delivering reliable opening response and long-term durability. MAP-controlled thermostats feature high-grade heater elements for fast electronic regulation, meeting the demands of modern engines. Thermostat housings are molded from premium PA66 from LG or cast aluminum, offering high heat resistance and dimensional stability. Our water temperature sensors and thermo switches use advanced sensing elements and gold-plated terminals to ensure precise readings and long service life. All components are tested for accuracy, sealing performance, and thermal cycling to meet OE standards.
