51127331600 Bumper Bracket | Rear Center Bumper Reinforcement

The 51127331600 Bumper Bracket utilizes hot-stamped boron steel construction with zinc-nickel anti-corrosion coating. Its three-dimensional laser-cut geometry matches original F10 chassis specifications within 0.4mm positional tolerance. The component features 8 M8 threaded inserts manufactured through cold-forming process for maximum thread integrity.

Surface treatment includes 7-stage phosphate conversion coating followed by cathodic electrocoating. The bracket's open-web design reduces weight by 22% compared to solid steel alternatives while maintaining 1800MPa tensile strength. Compatible with both standard and collision-repaired bumper assemblies.
