51118747849 Bracket | Front Bumper Lower Reinforcement Bracket for G38 LCI M-Sport

Specifically engineered for the BMW 5 Series G38 LCI M models (2018-2022), the 51118747849 Bracket delivers critical structural reinforcement to the front bumper assembly. This precision-crafted component serves as the primary mounting interface between the bumper cover and vehicle frame, distributing impact forces while maintaining alignment integrity. Manufactured from high-strength cold-rolled steel with zinc-nickel anti-corrosion treatment, the bracket withstands repeated stress cycles without deformation. Production incorporates laser-cut mounting holes positioned to ±0.2mm tolerance for factory-correct positioning. Post-forming heat treatment optimizes grain structure for enhanced fatigue resistance, while robotic welding ensures consistent joint integrity across all stress points.

The 51118747849 Bracket features vehicle-specific contouring that precisely follows the G38 LCI M bumper profile. Integrated reinforcement ribs provide torsional rigidity while reducing harmonic vibrations at highway speeds. Surface preparation includes phosphate conversion coating followed by electrostatic powder coating, creating a durable barrier against road chemicals and moisture intrusion. Installation requires no modification to existing bumper components, with all mounting points aligning with factory captive nuts. Designed to accommodate the increased aerodynamic loads of M Sport configurations, this bracket maintains structural integrity during high-speed driving while providing impact protection for critical cooling components. Production validation includes coordinate-measuring machine verification to ensure dimensional accuracy across all production batches.
