Dongfeng GX Truck Vehicle Body Parts High Quality Upper Grille - Bumper 8406035-C6220

The 8406035-C6220 Upper Front Bumper Grille Assembly is an original equipment (OE) front grille module specifically engineered for the Dongfeng Tianlong GX and KX Flagship series of high-end heavy-duty trucks. Positioned at the upper center section of the front bumper, this grille serves both aesthetic enhancement and functional aerodynamic performance, contributing to improved airflow management, cooling efficiency, and brand identity.

Constructed from high-strength ABS+PC composite plastic, it delivers excellent impact resistance, dimensional stability, and long-term UV protection. The design features a honeycomb or horizontal flow-channel pattern, optimized via CFD (Computational Fluid Dynamics) simulation to balance air intake volume with drag reduction—supporting fuel economy in high-speed logistics operations.

With its matte black UV-resistant finish or primed paint-ready surface, this grille integrates seamlessly into modern DFCV front-end styling while meeting safety standards related to pedestrian impact energy absorption.
