Dongfeng GX truck parts lower part of non-metallic middle bumper 8406614-C6200

Crafted from glass-fiber reinforced polypropylene (PP-GF22)—an upgrade from standard PP-GF20—the bumper lower part balances exceptional strength and lightweight design. Weighing only 2.4kg (42% lighter than aluminum alternatives), it reduces the truck’s front-end unsprung mass without compromising resilience. The PP-GF22 material exhibits 10% higher impact resistance than standard grades: it absorbs energy from minor collisions (up to 6km/h, e.g., curb scrapes) without cracking or permanent deformation, unlike brittle steel that bends or low-grade plastic that shatters. It also resists extreme temperatures, remaining functional at -35°C (colder than standard -30°C) and 90°C (hotter than standard 85°C), and passes 2200-hour UV aging tests with no brittleness—ensuring reliability in diverse climates, from freezing winters to hot summers

Exclusively tailored for 2022+ Dongfeng GX heavy-duty trucks (cargo, long-haul, dump variants), the 8406614-C6200 adheres strictly to original equipment (OE) specifications. Manufactured using 3D laser scanning of the GX’s middle bumper assembly and lower chassis, it achieves dimensional accuracy within ±0.15mm—matching every contour of the middle bumper upper part, front chassis brackets, and wheel well edges. The lower part includes 10 integrated snap-fit tabs (2 more than standard) and 5 pre-drilled holes that align perfectly with the middle bumper upper section and chassis mounting points, eliminating gaps that trap dirt or cause wind noise. It features a factory-applied textured black finish that matches the GX’s original middle bumper trim, avoiding post-installation painting and preserving the truck’s cohesive front-end appearance

Beyond protection, the 8406614-C6200 integrates practical design elements for enhanced performance. Its surface features 8mm-wide, 25°-angled vents that direct fresh air toward the lower radiator and intercooler, boosting heat dissipation by 15% compared to solid bumper lower parts—critical for preventing engine overheating during heavy-load operation (e.g., hauling cargo uphill). The vents also minimize wind resistance by reducing turbulent air under the middle bumper, contributing to a 0.6-0.9% improvement in fuel efficiency. For added utility, the lower part includes pre-cut slots for middle fog lamps (compatible with GX’s OEM fog lamp assemblies), eliminating the need for aftermarket drilling that weakens the bumper shell and risks water infiltration

The 8406614-C6200 is designed for efficient installation and minimal upkeep, ideal for fleet maintenance teams. It comes with a complete OE-spec hardware kit: 5 stainless steel self-tapping screws (M6×16), 10 replacement snap tabs (2 spares), a printed alignment guide, and 2 rubber gaskets (to prevent metal-to-plastic friction). Installation requires only basic hand tools (Phillips screwdriver, plastic pry tool) and can be completed by a single technician in 18-22 minutes: align the lower part with the middle bumper upper section using the guide, secure the snap tabs for initial hold, fasten the screws to 12±1 N·m (per Dongfeng’s torque specifications), and verify a 25mm clearance from the front axle. For maintenance, the PP-GF22 surface wipes clean with a damp cloth or pressure washer—no harsh chemicals needed—and the snap-fit design allows easy removal for chassis inspections, ensuring convenient access without damaging the bumper
