Dongfeng GX Left toolbox door assembly 5407009-C6100 in stocked

Built to withstand daily use and harsh operating conditions, the 5407009-C6100 assembly features a robust core structure. The door panel is crafted from 1.2mm-thick cold-rolled steel (Q235 grade), offering high impact resistance to prevent dents or bending from accidental collisions—common in construction, logistics, or off-road environments. The surface undergoes a two-step treatment: galvanization for corrosion resistance, followed by a powder-coating finish that resists scratches, UV damage, and chemical exposure (e.g., road salt, oil). Additionally, the door’s reinforcement ribs (located along the edges and center) enhance structural rigidity, ensuring it maintains shape even when storing heavy tools. Rigorous durability tests (10,000+ open/close cycles) confirm long-lasting performance, reducing maintenance costs

A key design focus of the 5407009-C6100 assembly is its advanced weatherproof sealing, safeguarding the toolbox’s interior from external elements. The door’s perimeter is fitted with a high-density EPDM rubber gasket, which compresses tightly against the toolbox frame when closed, creating a waterproof and dustproof barrier. This gasket resists hardening, cracking, or shrinking even in extreme temperatures (-30°C to 80°C), ensuring consistent sealing performance in rain, snow, or dusty work sites. Additionally, the door’s latch mechanism (included in the assembly) features a moisture-resistant coating, preventing rust that could cause jamming. By keeping tools, spare parts, or documents dry and clean, this assembly preserves the value and usability of stored items

The 5407009-C6100 assembly prioritizes user convenience with its intuitive latch system and ergonomic design. The integrated latch is a spring-loaded, push-to-open mechanism that requires minimal force to operate—even with gloved hands, a critical feature for workers in industrial settings. When closed, the latch engages securely to prevent accidental opening during vehicle movement, while a built-in release tab allows quick access. The door also includes a recessed handle (molded into the panel) that provides a comfortable grip, avoiding sharp edges and ensuring easy opening/closing. Additionally, the door’s weight is balanced to align with Dongfeng GX’s original hinge system, preventing sagging over time and maintaining smooth operation

Designed for efficiency, the 5407009-C6100 assembly simplifies installation, minimizing vehicle downtime for both professional technicians and DIY users. It includes all necessary mounting hardware (bolts, washers, and the latch mechanism) pre-packaged, eliminating the need for separate purchases. The door’s pre-drilled holes align precisely with Dongfeng GX’s factory hinge and latch mounting points, and clear alignment marks on the panel guide quick positioning. Installation requires only basic hand tools (socket wrench, screwdriver) and can be completed in 45 minutes or less—ideal for commercial fleets that rely on toolbox access for daily operations. A detailed installation manual (with step-by-step diagrams) is also included, ensuring correct fitment and avoiding errors that could compromise functionality
