Dongfeng GX truck parts White non-metallic bumper with bracket assembly 8406610-C6204

Crafted from glass-fiber reinforced polypropylene (PP-GF20)—a premium non-metallic material—the bumper shell balances lightweight performance and heavy-duty protection. The assembly weighs only 6.8kg (40% lighter than steel bumper+bracket combinations), reducing the truck’s unsprung mass and improving fuel efficiency by ~2.5% over 100,000km of operation. Despite its light weight, PP-GF20 exhibits exceptional impact resilience: it absorbs and disperses energy from low-speed collisions (up to 6km/h) without cracking or permanent deformation—unlike brittle steel that bends or plastic that shatters. Testing confirms the bumper retains structural integrity after 15+ minor impacts (e.g., debris collisions, curb scrapes), and its flexibility prevents stress fractures in extreme temperature cycles (-30°C to 80°C)

The assembly features a factory-applied automotive-grade white finish that matches Dongfeng GX’s original color code, ensuring seamless visual integration with the truck’s front end. The finish undergoes a three-step curing process (primer → base coat → clear coat) that delivers scratch resistance (passes 3H pencil hardness tests) and UV stability—maintaining its bright white appearance for over 6 years without fading, even under prolonged sun exposure (2000-hour xenon lamp aging test certified). In terms of fit, the bumper shell is 3D-molded to match the GX’s front grille, headlight housings, and fog lamp cutouts—eliminating unsightly gaps that plague aftermarket bumpers. The pre-installed brackets also align perfectly with the chassis’s mounting points, ensuring the bumper sits flush with the truck’s body lines, preserving a professional fleet appearance

Engineered to protect the truck’s front-end systems, the assembly covers key components including the radiator, oil cooler, headlight lower housings, and fog lamps. The bumper’s 3.5mm-thick outer shell and internal reinforcing ribs (spaced 70mm apart) form a rigid barrier that deflects road debris (rocks, gravel) and minimizes damage from minor collisions. Its lower edge includes a 25mm-tall skid lip that prevents the bumper from catching on uneven terrain (e.g., construction sites, unpaved roads), while the upper edge is contoured to channel water and mud away from the engine bay—reducing corrosion risk for chassis components. For added utility, the bumper includes pre-cut holes for fog lamps (compatible with GX’s OEM fog lamp assemblies), eliminating the need for aftermarket drilling that weakens the shell

The PP-GF20 material and factory finish make the 8406610-C6204 assembly highly resistant to harsh conditions, ideal for trucks operating across diverse climates. It is impervious to water, salt, and humidity—preventing rust (a major issue with steel bumpers) in coastal or snowy regions. The material also resists degradation from road chemicals, including de-icing salts, diesel fuel, and engine oil: testing shows no discoloration or material breakdown after 600+ hours of exposure. Additionally, the assembly maintains performance in extreme temperatures: it remains flexible at -30°C (avoiding brittleness) and does not warp at 80°C (engine bay heat), ensuring reliable protection year-round. The non-metallic construction also eliminates electrolytic corrosion (common between steel brackets and aluminum chassis), extending the assembly’s service life to over 10 years
