Product Description

The 51137352091 Trim provides comprehensive front threshold protection for BMW X1 F49 models through advanced polymer engineering featuring UV-resistant additives that maintain color integrity under sun exposure. Precision-molded contours replicate factory body lines within ±0.25mm tolerance, enabling seamless visual integration with vehicle design language. Integrated drainage channels prevent water accumulation while specialized non-slip surface texturing ensures secure footing during vehicle entry. Reinforced mounting points distribute structural loads across multiple contact areas, and integrated sealing ridges create moisture barriers protecting underlying metal components from corrosion. Abrasion-resistant coating withstands repeated shoe contact while impact-dispersing matrix absorbs door closure vibrations. The polymer formulation maintains dimensional stability across extreme temperatures (-35°C to 115°C), preventing warping or cracking. Vehicle-specific curvature accommodates body flex while maintaining uniform panel gaps along the entire threshold length.
