Dongfeng KC Installation bracket for top cover interior panel B 5702086-C0300

Constructed from 1.5mm-thick high-strength cold-rolled steel (Q235 grade), this installation bracket delivers exceptional load-bearing capacity and structural rigidity—critical for securely holding the top cover interior panel (which typically weighs 2.5-3kg) in place during truck operation. The cold-rolled steel undergoes a stamping process to form a reinforced, angular structure that distributes weight evenly across the cab’s roof support beams, preventing bending or deformation under the panel’s weight or vibration. It also features a folded edge design (with a 5mm flange) that enhances impact resistance, protecting the bracket from damage during interior panel installation or cab maintenance. Through mechanical testing, the bracket withstands a static load of up to 15kg (6x the panel’s weight) without permanent deformation, ensuring long-term stability even in rough driving conditions (e.g., off-road construction sites or uneven highways)

To withstand the potentially humid or dusty environment inside truck cabs, the 5702086-C0300 bracket is treated with a multi-layer anti-corrosion coating system. First, it undergoes a zinc phosphate pretreatment to create a porous base layer that improves coating adhesion. Then, it is coated with an electrophoretic (E-coat) primer—providing uniform coverage even in hard-to-reach areas (e.g., mounting hole interiors) and forming a barrier against moisture. Finally, a top layer of high-temperature powder coating (available in black to match the KC’s interior trim) is applied, resisting scratches, oil, and dust while preventing color fading. This coating system meets the ISO 10289 standard for corrosion resistance, withstanding 500+ hours of salt-spray testing without rust or coating peeling. This ensures the bracket remains durable even in cabs exposed to condensation (e.g., temperature changes) or occasional spills, extending its service life to match the Dongfeng KC’s 8-10 year typical lifespan

Engineered to ensure the top cover interior panel B is installed with precision and stability, the bracket features a multi-point mounting design with three key functional areas. Two “fixed mounting points” (equipped with threaded holes) attach securely to the cab’s roof support beams, providing a stable base. A third “adjustable mounting point” (with a slotted hole) allows for ±2mm of lateral adjustment during installation, compensating for minor variations in the interior panel’s dimensions or cab frame alignment—ensuring the panel sits flush with adjacent interior components (e.g., A-pillars or front header trim). Additionally, the bracket includes a small locating tab that fits into a corresponding notch on the interior panel, preventing horizontal shifting of the panel during driving. This multi-point design not only secures the panel but also maintains the KC’s interior aesthetic, avoiding unsightly gaps or misaligned trim that can occur with generic brackets

Designed for hassle-free installation by technicians or fleet maintenance teams, the 5702086-C0300 bracket requires no specialized tools or complex modifications. It comes with pre-threaded holes (M6 size) that accept the Dongfeng KC’s original interior panel mounting screws (included with the bracket), eliminating the need for drilling or tapping. The bracket’s compact size (120mm x 45mm x 30mm) and lightweight design (only 85g) make it easy to handle in the tight space of the cab roof. Clear alignment marks (etched into the bracket’s surface) help technicians quickly position it correctly relative to the cab frame and interior panel, reducing installation time to less than 10 minutes per bracket (multiple brackets are typically used for the full interior panel). For maintenance, the bracket’s simple, one-piece construction allows for easy removal and replacement—if damaged, it can be swapped out without removing the entire interior panel, minimizing vehicle downtime and repair costs for Dongfeng KC operators
