Dongfeng GX Lower right decoupling pin cover 8406062-C6200

Constructed from a high-performance blend of thermoplastic olefin (TPO) and ethylene propylene diene monomer (EPDM) (ratio 80:20), the 8406062-C6200 cover balances rigidity for shape retention and flexibility for impact resistance. With a thickness of 4.2mm, the material exhibits excellent low-temperature toughness (notched Izod impact strength of 8.3 kJ/m² at -35°C), avoiding cracking in cold climates, and high-temperature stability (resistant to warping at 90°C) during summer heat or under-hood radiation. The EPDM component enhances chemical resistance, withstanding degradation from diesel, brake fluid, and road salts even after 600 hours of exposure. Infused with UV-stabilizers, the blend passes 2200-hour xenon lamp aging tests with no brittleness or color fading, ensuring durability in outdoor, under-vehicle environments for over 7 years

Exclusively tailored for Dongfeng GX heavy-duty trucks (including cargo, long-haul, and dump variants), the 8406062-C6200 cover strictly adheres to original equipment (OE) specifications. Manufactured using 3D laser scanning of the GX’s lower right decoupling pin assembly and injection molding with CNC tooling, it achieves dimensional accuracy within ±0.15mm—matching every contour, groove, and mounting feature of the pin and surrounding bracket. The cover features a snap-fit design with 4 integrated retaining tabs that lock into the pin’s bracket recesses, creating a gap-free seal (IP65 dust/water resistance rating) that prevents contaminant infiltration. It is fully compatible with all Dongfeng GX models produced since 2022, including those with upgraded suspension systems, requiring no modification to the decoupling pin or bracket

The 8406062-C6200 cover is engineered for hassle-free, tool-free installation—ideal for truck fleet maintenance teams or on-site repairs. Installation involves aligning the cover’s retaining tabs with the decoupling pin bracket’s grooves and applying gentle, even pressure until an audible “click” confirms secure attachment. A single technician can complete the process in 3-5 minutes, eliminating the need for specialized tools, adhesives, or hardware. The snap-fit design resists vibration (tested to 10-2500 Hz frequency range), ensuring the cover stays firmly in place even on rough terrain or during heavy-load operation. For replacement, the cover can be easily removed by prying the tabs with a plastic tool (included in optional service kits), avoiding damage to the decoupling pin or bracket

Designed for minimal upkeep, the 8406062-C6200 cover features a smooth, non-porous surface that repels dirt and mud—daily cleaning requires only a damp cloth or quick hose-down, no harsh chemicals needed. The cover’s outer surface is marked with a high-visibility yellow identification stripe (3mm wide), making it easy for technicians to locate the decoupling pin during inspections or maintenance, reducing service time. Additionally, the cover’s inner surface is lined with a soft, oil-resistant felt pad that protects the decoupling pin’s original finish from scratches during installation and use, maintaining the component’s structural integrity. The cover also includes a 12-month warranty against material defects (e.g., cracking, tab breakage) and manufacturing errors, ensuring long-term reliability for truck operators
