51117349363 Molding | Precision Lower Rocker Protection for 5-Series Vehicles
51117349363 Molding: Rocker Panel Finisher for BMW 5-Series F10/F11/F07
Specifically engineered for BMW 5-Series vehicles produced between 2010-2017, the 51117349363 Molding combines aerodynamic refinement with impact protection through its glass-reinforced polypropylene construction. The precisely extruded profile features integrated drainage channels and thermal expansion joints that maintain structural integrity across temperature extremes from -22°F to 176°F. UV-stabilized matte black surface resists fading while hydrophobic treatment prevents road salt adhesion. Aerodynamically optimized contours reduce wind noise by 18% at highway speeds compared to aftermarket alternatives. The 51117349363 Molding integrates seamlessly with factory jacking point covers and M Sport side skirts through precision-engineered end caps that maintain original body lines.
Technical Specifications: 51117349363 Molding
Material Science
Glass-fiber reinforced copolymer matrix provides 43% higher impact resistance than standard polypropylene while maintaining flexibility at sub-zero temperatures. Multi-layer UV protection system combines pigment stabilization with surface resin coating to prevent color fading. Chemical-resistant formulation withstands prolonged exposure to road salts, brake dust, and automotive fluids. Precision extrusion process ensures consistent wall thickness within ±0.15mm tolerances across the entire 1480mm length. Internal reinforcement ribs increase stiffness by 27% compared to previous generation moldings while reducing overall weight. Sacrificial impact zones absorb 15J of energy during low-speed collisions to protect underlying body panels.
Functional Design
Aerodynamically tuned leading edge reduces air turbulence by 22% at 75mph compared to flat profiles. Integrated alignment guides ensure ±1.5mm installation precision across the rocker panel length. Thermal expansion compensation joints accommodate 4.2mm of dimensional change during temperature swings. Factory-spec mounting channels accept original fasteners without modification or additional hardware. End cap sealing system prevents debris ingress at bumper junctions while allowing natural panel movement. Ground clearance maintains factory specifications within ±3mm tolerance across all suspension configurations. Compatible with OEM mud flaps and side skirt extensions through precision-molded connection points.
Verified fitment for BMW F10 Sedan, F11 Touring, and F07 Gran Turismo models. Compatible with all engine configurations including N20/N55/N63 gasoline, N47/N57 diesel, and ActiveHybrid 5 powertrains. Maintains proper clearance for adaptive suspension systems and factory-installed side skirts. Accommodates both standard and M Sport body kits through vehicle-specific contouring. Designed for precise integration with factory jacking point covers and underbody panels. Confirmed compatibility with all-wheel drive variants and vehicles equipped with enhanced cooling packages.
