51128745742 Moulding | BMW X7 G07 M Rear Right Rocker Panel

51128745742 Moulding - Rear Right Side Skirt Enhancement

Precision-engineered aerodynamic component for BMW X7 G07 models, the 51128745742 Moulding integrates seamlessly with factory body contours to optimize undercarriage airflow dynamics while providing enhanced protection against road debris impacts. This chrome-accented rocker panel molding features advanced polymer construction with UV-resistant surface treatment that maintains its lustrous appearance through extreme weather conditions. The precisely contoured design follows the vehicle's rear quarter panel curvature, creating a visual extension of the signature BMW character line while functionally reducing turbulent airflow around wheel arches. Integrated mounting points utilize vibration-dampening hardware that maintains structural integrity on rough terrain, with specialized sealing channels preventing moisture intrusion into body cavities. Manufactured to BMW Group tolerances, this molding maintains consistent 0.8mm panel gaps along its entire length while providing impact resistance against stones and debris thrown up at highway speeds. The chrome-finish insert is triple-layer coated for corrosion resistance, while the main body section incorporates glass-fiber reinforcement for dimensional stability across temperature extremes from -40°C to 85°C operational environments.

Vehicle Compatibility Specifications

Designed exclusively for BMW X7 G07 platform vehicles with M Sport or M Performance packages, the 51128745742 Moulding corresponds to right-rear positioning while the complementary 51128745741 serves the left-rear position. This component maintains compatibility with all wheelbase configurations and powertrain variants including xDrive40i, M50i, and Alpina XB7 models from 2019-2023 production years. The molding's geometric profile accommodates both standard and air suspension configurations while providing clearance for factory-installed running boards. Installation compatibility extends to vehicles equipped with rear-wheel steering systems, with precise contouring to avoid interference with suspension components at full articulation. This aerodynamic solution maintains factory-specified ground clearance while providing enhanced protection to lower body panels and door sills against road debris impacts. Verify specific vehicle configuration using VIN decoding to ensure proper integration with optional equipment packages.

Engineering Specifications

Manufactured through dual-material co-extrusion, the 51128745742 Moulding combines impact-modified thermoplastic olefin (TPO) with glass-fiber reinforcement exceeding ISO 180 impact resistance standards. The main body section features UV-stabilized polymer formulation that withstands 3000+ hours of accelerated weathering testing while maintaining color stability. Precision-engineered mounting points maintain ±0.5mm positional accuracy relative to factory attachment locations, with stainless steel retention clips rated for 500+ installation cycles. The chrome accent strip utilizes PVD (Physical Vapor Deposition) coating technology that provides 10X improved corrosion resistance compared to conventional electroplating. Internal reinforcement ribs prevent deformation under aerodynamic loads exceeding 150km/h, while integrated drainage channels prevent water accumulation. Production validation includes coordinate measuring machine (CMM) verification to ensure dimensional conformity across all sealing surfaces and attachment interfaces.
