This OE 5301509-CS030Y primer front mask is strictly produced per Dongfeng Bright X9 original factory mold specifications. The inner dense grid reinforced rib structure greatly improves overall rigidity, effectively resisting minor front collision deformation and long-term road vibration bending. The uniform white primer base surface has excellent paint adhesion performance, supporting any custom water-based or solvent topcoat color matching to fleet cab livery. All mounting holes and positioning buckles are pre-formed according to vehicle body standards, realizing seamless gap-free installation without cutting or drilling modification, fully restoring factory front fascia structural protection performance.
