Dongfeng GX Rear mudguard right bracket assembly 8403070-C6103

To endure the under-vehicle harsh conditions (rain, road salt, humidity, and industrial dust) that commercial vehicles face, the 8403070-C6103 bracket undergoes a rigorous anti-corrosion treatment process. First, a zinc phosphate pretreatment (11-13μm thick) creates a corrosion-resistant base and enhances coating adhesion. Next, an electrophoretic primer (22-26μm thick) provides uniform coverage, including hard-to-reach rib crevices. The final layer is a black polyester powder coating (75-85μm thick) that meets ISO 10289 standards, passing 1200-hour neutral salt spray tests without red rust or coating peeling. This protection ensures the bracket maintains structural integrity for over 9 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 rear mudguard right bracket strictly adheres to the original equipment (OE) specifications of part number 8403070-C6103. Manufactured using 3D laser scanning and robotic welding, it achieves dimensional accuracy within ±0.2mm—perfectly aligning with the Dongfeng GX’s rear axle frame, mudguard mounting points, and underbody contour. The bracket’s overall dimensions (length: 400mm × width: 170mm × height: 130mm) match the vehicle’s underbody space exactly, eliminating gaps that could cause abnormal noise or mud accumulation. It is fully compatible with all Dongfeng GX models produced since 2021, making it a direct replacement part for factory assembly or after-sales repairs—no trimming or drilling required

Beyond basic support, the 8403070-C6103 bracket is engineered to optimize the rear mudguard’s protective function. It features a precision-machined mudguard interface with 6 M10 threaded holes (15mm depth) that ensure the mudguard is mounted at a 15° angle—this angle redirects water and debris downward, minimizing splashing on following vehicles while preventing mud from accumulating between the bracket and mudguard. The bracket also includes a 2mm-thick rubber gasket between the mudguard and bracket surface, which absorbs vibration (reducing mudguard wear by 30%) and creates a waterproof seal to block moisture from seeping into the mounting holes. Additionally, the bracket’s lower edge is curved to avoid interfering with the rear wheel’s movement, even when the vehicle is fully loaded

The 8403070-C6103 bracket assembly is designed for user-friendly installation and minimal upkeep. It comes with a complete hardware kit, including 6 grade 8.8 high-strength bolts, lock nuts, washers, and rubber gaskets—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 25-30 minutes, 40% faster than non-OE brackets. For maintenance, the smooth powder-coated surface can be cleaned with a damp cloth to remove mud 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
