51127226939 Center Bracket: Central Reinforcement for E70 X5 Rear Assembly
Engineered for 2010-2013 BMW E70 X5 LCI models, the 51127226939 Center Bracket provides critical midline support between the rear bumper cover and vehicle substructure. This structural plastic component distributes impact forces across the bumper assembly while maintaining dimensional stability in temperature extremes (-40°C to +85°C operational range). The glass-fiber reinforced polypropylene construction features UV-stabilized formulation to prevent material degradation, with injection-molded ribs matching OEM geometric patterns for perfect sensor alignment. Precisely positioned mounting bosses accept factory fasteners without modification, while integrated alignment guides ensure 2mm installation tolerance for parking assist system calibration.
Technical Specifications: 51127226939 Center Bracket
Material Engineering
Manufactured from 30% glass-fiber reinforced PP-T40 material with ISO 527-2 tensile strength rating of 75MPa. The dual-stage injection molding process creates structural ribs with 2.8mm wall thickness in critical load areas. UV stabilization additives provide 10+ years of sunlight resistance without embrittlement. All mounting surfaces feature CNC-machined flatness within 0.15mm tolerance to prevent bumper cover distortion. The material formulation passes FMVSS 302 flammability requirements with self-extinguishing properties.
Functional Design
Maintains 4.5mm clearance from exhaust components in all drivetrain configurations. The asymmetric rib pattern accommodates both left-hand and right-hand drive variants without modification. Integrated cable routing channels protect parking sensor wiring from abrasion. All fastener receptacles include steel reinforcement inserts to prevent thread stripping during torque application (8-10Nm specification). The bracket's energy absorption design complies with ECE R42 low-speed impact standards while supporting up to 15kg auxiliary loads from bumper-mounted accessories.
Vehicle Compatibility Information
Direct replacement for all 2010-2013 BMW E70 X5 LCI models including xDrive35i, xDrive50i, and xDrive30d variants. Not compatible with pre-LCI models or vehicles equipped with factory trailer hitch packages requiring reinforced brackets. The 51127226939 Center Bracket maintains proper functionality of rear parking sensors and backup camera systems when installed with original fasteners. For optimal performance, inspect and replace all related mounting hardware during installation.
