Dongfeng GX truck parts Left side exterior rearview mirror and support assembly 8201005-C6107

The assembly’s support arm is constructed from high-strength 45# seamless steel (outer diameter: 34mm, wall thickness: 5.5mm) with a reinforced triangular mounting base, delivering a maximum static load capacity of 280N. This easily supports the mirror assembly’s weight (5.2kg) plus dynamic forces from high-speed wind (tested to 145 km/h) and road vibration. The steel undergoes quenching and tempering treatment, achieving a tensile strength of ≥680 MPa and yield strength of ≥400 MPa—resisting bending, twisting, or deformation even on rough highways. The support arm is welded to a 6mm-thick steel mounting plate with 5 pre-drilled holes (M10 threaded), ensuring a secure attachment to the truck’s cab. This robust structure prevents mirror misalignment, even during long-haul trips over uneven terrain, maintaining consistent visibility for over 9.5 years

To avoid blurred visibility from vibration, the 8201005-C6107 assembly integrates dual-layer anti-vibration technology. The mirror head is mounted on a rubber damping bracket (shore hardness: 62±5A) with a steel spring core, absorbing 85% of road vibration (frequency range: 10-3200 Hz)—reducing mirror shake by 92% compared to standard assemblies. The support arm’s streamlined aerodynamic shape (optimized via wind tunnel testing) reduces wind resistance by 38%, 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 wear-resistant POM (polyoxymethylene) washer, allowing 360° angular adjustment while maintaining position stability—even under strong crosswinds (up to 65 km/h)

Exposed to rain, road salt, humidity, and UV radiation, the assembly undergoes a rigorous three-step anti-corrosion treatment. First, a zinc phosphate pretreatment (14-16μm thick) creates a corrosion-resistant base and enhances coating adhesion. Second, an electrophoretic primer (22-26μm thick) provides uniform coverage—even in hard-to-reach areas like the support arm’s inner tube. Finally, a black polyester powder coating (80-90μm thick) meets ISO 10289 standards, passing 1400-hour neutral salt spray tests without red rust. The mirror housing is made of impact-resistant ABS+PC composite plastic with a UV-stabilized coating, preventing color fading and brittleness—passing 2400-hour xenon lamp aging tests with no structural damage. This protection ensures durability in coastal, snowy, or industrial areas

Exclusively tailored for Dongfeng GX heavy-duty trucks (including long-haul, cargo, and dump variants), the 8201005-C6107 assembly strictly adheres to OE specifications. Manufactured using 3D laser scanning of GX cab exteriors and CNC machining, it achieves dimensional accuracy within ±0.1mm—matching the cab’s left-side mounting points exactly (no drilling/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 32-38 minutes (48% faster than non-OE assemblies). For daily use, the mirror head features a tool-free adjustment knob that lets drivers fine-tune the angle with one hand, adapting to different heights or driving scenarios. The mirror glass is also replaceable separately, reducing maintenance costs if damaged by stones or debris
