51117331764 Bumper Trim | Structural & Aesthetic Integration

The 51117331764 Bumper Trim utilizes glass-fiber reinforced polypropylene with CNC-machined surface texturing that replicates OEM light diffusion patterns. Its interlocking edge design maintains 0.5mm panel gap consistency across temperature variations from -40°C to 110°C. The three-stage injection molding process ensures 0.1mm dimensional accuracy for seamless integration with bumper contours.

Aerodynamic underbody channels reduce high-speed wind noise by 19dB compared to standard replacements. The thermal-compensated mounting system allows ±3mm bumper flex without stress fractures, using stainless steel reinforcement clips rated for 75,000 vibration cycles. Pre-aligned sensor cutouts maintain functionality with parking assist systems.
