Dongfeng GX truck parts Upper step right bracket assembly 8405272-C6101

Exposed to road salt, rain, and mud under trucks, the 8405272-C6101 bracket undergoes a rigorous anti-corrosion treatment to extend service life. The process includes zinc phosphate pretreatment (12-14μm thick) for adhesion, an electrophoretic primer (22-26μm thick) for uniform coverage (even in rib crevices), and a black polyester powder coating (75-85μm thick) that meets ISO 10289 standards. This system passes 1200-hour neutral salt spray tests without red rust, protecting against corrosion in coastal or snowy regions. The coating also resists scratches from boots or tools, maintaining structural integrity for over 8 years—reducing maintenance costs and replacement frequency for truck fleets

Exclusively tailored for Dongfeng GX heavy-duty trucks (including cargo and long-haul models), the 8405272-C6101 bracket strictly adheres to original equipment (OE) specifications. Manufactured using 3D laser cutting and robotic welding, it achieves dimensional accuracy within ±0.2mm—perfectly aligning with the truck’s right-side cab frame, step mounting points, and underbody brackets. Its overall dimensions (length: 280mm × width: 160mm × height: 110mm) match the GX’s cab contour exactly, eliminating gaps that could trap debris or cause abnormal noise. The bracket is fully compatible with all Dongfeng GX truck models produced since 2021, making it a direct replacement part for factory assembly or after-sales repairs—no drilling or modification required

Beyond basic support, the 8405272-C6101 bracket is engineered to optimize the upper step’s performance. It features a precision-machined step interface with 6 M8 threaded holes (15mm depth) that secure the step pad at a 10° anti-slip angle, preventing foot slippage during boarding. The bracket also includes 2mm-thick rubber gaskets between the step pad and bracket, which absorb vibration (reducing step wear by 30%) and block moisture from seeping into mounting holes. Its lower edge is curved to avoid interfering with truck tires or suspension components, even when the vehicle is fully loaded—ensuring no contact during rough road travel

The 8405272-C6101 bracket assembly is designed for hassle-free installation and minimal upkeep, ideal for truck fleets needing efficient servicing. It comes with a complete hardware kit: 6 grade 8.8 high-strength bolts, lock nuts, washers, and rubber gaskets—no additional parts needed. The lightweight design (5.2kg) and clear laser-engraved alignment marks allow two technicians to install it in 20-25 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 steel structure requires no periodic inspections beyond standard truck servicing. It also includes a 24-month warranty against material defects (e.g., welding cracks, coating peeling) and manufacturing errors, providing reliability for fleet managers
