Dongfeng GX truck parts Front rearview mirror assembly 8219010-C6200

The assembly’s support arm is constructed from high-strength 40Cr alloy steel (outer diameter: 32mm, wall thickness: 5mm) with a one-piece forged structure, delivering a maximum static load capacity of 250N—easily supporting the mirror assembly’s weight (4.5kg) plus dynamic forces from high-speed wind (tested to 140 km/h) and road vibration. The steel undergoes quenching and tempering treatment, achieving a tensile strength of ≥650 MPa and yield strength of ≥380 MPa, which resists bending, twisting, or deformation. The mirror housing is made of impact-resistant ABS+PC composite plastic (thickness: 3mm) that can withstand collisions with small debris (e.g., stones, branches) without cracking. This robust structure prevents mirror misalignment or housing damage even on rough highways, maintaining consistent visibility for over 9 years of use

To avoid blurred visibility from vibration, the 8219010-C6200 assembly integrates advanced anti-vibration technology. The mirror head is mounted on a dual-layer rubber damping bracket (shore hardness: 60±5A) that absorbs 80% of road vibration (frequency range: 10-3000 Hz), reducing mirror shake by 90% compared to standard assemblies. The support arm’s streamlined aerodynamic design reduces wind resistance by 35% (tested in wind tunnels), minimizing wind-induced flutter that blurs visibility at high speeds. Additionally, the mirror’s pivot joint uses a precision-machined ball-and-socket mechanism with a high-friction POM washer, allowing 360° angular adjustment while maintaining position stability—even under strong crosswinds (up to 60 km/h)

Exposed to rain, road salt, humidity, and UV radiation, the assembly undergoes a rigorous anti-corrosion treatment to extend service life. The support arm and mounting plate receive a three-step coating process: 1) zinc phosphate pretreatment (13-15μm thick) for coating adhesion; 2) electrophoretic primer (20-24μm thick) for uniform corrosion resistance (even in hard-to-reach areas); 3) black polyester powder coating (75-85μm thick) that meets ISO 10289 standards. This system passes 1300-hour neutral salt spray tests without red rust, protecting against corrosion in coastal, snowy, or industrial areas. The mirror housing is coated with a UV-stabilized paint that resists color fading and brittleness—passing 2200-hour xenon lamp aging tests with no peeling or discoloration

Exclusively tailored for Dongfeng GX heavy-duty trucks (including cargo, long-haul, and dump variants), the 8219010-C6200 assembly strictly adheres to original equipment (OE) specifications. Manufactured using 3D laser scanning and CNC machining, it achieves dimensional accuracy within ±0.12mm—perfectly aligning with the truck’s cab front mounting points (no drilling or modification required). The assembly includes a complete hardware kit: 5 grade 10.9 high-strength bolts, lock nuts, and anti-vibration washers—allowing two technicians to install it in 30-35 minutes (45% faster than non-OE assemblies). For user convenience, the mirror head features a tool-free adjustment lever that lets drivers fine-tune the angle with one hand, adapting to different driving heights and scenarios. The mirror glass is also replaceable separately, reducing maintenance costs if damaged (e.g., from stone impacts)
