51137336646B Safety Bracket | Structural Reinforcement Component

Engineered to exacting standards, the 51137336646B Safety Bracket features cold-forged steel construction with zinc-nickel anti-corrosion coating. The multi-axis design incorporates six strategic reinforcement points that distribute impact forces across 180° angular planes. Precision laser-cut mounting holes maintain ±0.25mm positional accuracy for OEM-compliant installation.

Three-stage surface treatment combines phosphate conversion coating with electrostatic powder coating, achieving 800-hour salt spray resistance. The interlocking rib structure increases torsional rigidity by 40% compared to conventional designs. Compatibility extends across 35+ vehicle platforms with model-specific contour adaptation.
