51137397869 Trim | Rear Door Bright Black Molding System
51137397869 Trim
Precisely crafted for BMW 7 Series G11/G12 models, this bright black 51137397869 Trim creates seamless visual continuity along the rear door surfaces while adding protective reinforcement to the door edge. The deep gloss finish maintains its reflective quality through years of exposure.
Product Description
The 51137397869 Trim transforms the rear door profiles of BMW 7 Series G11/G12 models with its sophisticated bright black finish. Engineered as a critical exterior accent piece, this molding attaches along the door's upper edge to create visual separation while protecting vulnerable door edges from parking impacts. The high-gloss surface treatment achieves deep chromatic depth that resists micro-scratches and UV degradation. Flexible mounting clips distribute installation pressure evenly across the entire length, eliminating stress points that could cause deformation. Precision-engineered curvature matches factory door contours perfectly without gaps or misalignment shadows. Integrated moisture channels prevent water accumulation behind the trim while maintaining consistent adhesion along the entire surface. The rigid core structure maintains dimensional stability during temperature extremes ranging from -30°C to 85°C operational environments. Rear door specific design accounts for unique curvature requirements compared to front door applications. Dual-component construction combines impact-resistant polymer core with UV-stabilized gloss top layer that maintains its reflective quality for over 50,000 sun-hours. Seamless end caps eliminate sharp edges while creating smooth transitions at termination points. The bright black color coordinates with factory shadowline trim packages while providing elegant contrast against lighter paint colors. Installation alignment guides ensure perfect positioning without measurement tools or trial adjustments.

Technical Specifications
Material Composition
UV-resistant polymer core with scratch-resistant gloss coating, reinforced with fiberglass strands for dimensional stability. Hydrophobic top layer repels water spots and road contaminants.
Structural Design
Precision-curved profile matches factory door curvature within 0.5mm tolerance. Integrated mounting clips with stainless steel retention springs maintain constant pressure without deformation.
Environmental Resistance
Withstands temperature cycling from -30°C to 95°C without warping or adhesive failure. Chemical-resistant surface repels automotive fluids, de-icing salts, and environmental pollutants.
Optical Properties
Deep-gloss finish maintains 98% reflectivity after 5 years UV exposure. Color-stable pigments prevent fading or yellowing. Micro-textured surface minimizes light-scattering scratches.
Compatible Product Declaration
Compatible with 2015-2022 BMW 7 Series G11/G12 models requiring rear door bright trim replacement. This component aligns with original equipment specifications for bright black exterior trim applications. Verified OE references: 51137397869 (left), 51137397870 (right).
