Dongfeng GX Wheel cover right bracket assembly 8403456-C6200

To endure the harsh under-vehicle conditions (rain, road salt, humidity, and brake dust) that commercial vehicles face, the 8403456-C6200 bracket undergoes a rigorous three-step anti-corrosion process. First, a zinc phosphate pretreatment (12-14μm thick) creates a corrosion-resistant base and enhances coating adhesion. Next, an electrophoretic primer (23-27μm thick) provides uniform coverage—even in hard-to-reach rib crevices—blocking moisture from contacting the steel. The final layer is a black polyester powder coating (78-88μm thick) that meets ISO 10289 standards, passing 1300-hour neutral salt spray tests without red rust or coating peeling. This protection ensures the bracket maintains structural integrity for over 9.5 years—even in coastal or high-salt regions—reducing maintenance costs and replacement frequency

Exclusively tailored for Dongfeng GX commercial vehicles (including heavy-duty trucks and cargo models), this wheel cover right bracket strictly adheres to original equipment (OE) specifications of part number 8403456-C6200. Manufactured using 3D laser cutting and robotic welding technology, it achieves dimensional accuracy within ±0.18mm—perfectly aligning with the Dongfeng GX’s right wheel hub, frame brackets, and wheel cover mounting points. The bracket features 8 pre-drilled mounting holes (M8 threaded, 15mm depth) with precision-threaded inserts, ensuring a tight fit with the wheel cover’s attachment points—eliminating gaps that could cause wind noise or debris accumulation. It is fully compatible with all Dongfeng GX models produced since 2022, including those with 22.5-inch or 24.5-inch wheels, making it a direct replacement part for factory assembly or after-sales repairs

Beyond basic support, the 8403456-C6200 bracket is engineered to optimize the wheel cover’s protective function for the right wheel hub. It includes a 2mm-thick rubber cushion pad at each mounting interface between the bracket and wheel cover, which absorbs 65% of vibration—reducing wear on both components and extending the wheel cover’s service life by 35%. The bracket’s inner edge is curved to avoid interfering with the wheel’s rotation or brake caliper movement, even when the vehicle is fully loaded (up to the GX’s maximum payload capacity). Additionally, the bracket features a small drainage slot (5mm diameter) at the bottom to channel rainwater and road salt away from the wheel hub, preventing corrosion of hub bearings and bolts—critical for maintaining wheel safety

The 8403456-C6200 bracket assembly is designed for user-friendly installation and minimal upkeep. It comes with a complete hardware kit, including 8 grade 8.8 high-strength bolts, lock nuts, washers, and rubber cushion pads—eliminating the need for separate part sourcing. The bracket’s lightweight design (6.8kg) and clear laser-engraved alignment marks allow two technicians to install it in 22-28 minutes, 45% faster than non-OE brackets that require custom modifications. For maintenance, the smooth powder-coated surface can be cleaned with a damp cloth to remove mud, brake dust, or debris, and the robust structure requires no periodic inspections beyond standard vehicle servicing. It also includes a 24-month warranty against material defects (e.g., welding cracks, coating peeling) and manufacturing errors, providing confidence for Dongfeng GX owners and repair facilities
