Bracket, Rear Bumper Outer Mounting, LH for Tesla Model S (2021-) | 1585737-00-B (CFN Brand)

1. Basic Information

2. Core Selling Points

• OEM-Precise Fit & Alignment: Precision-stamped using Tesla’s original CAD design data, with dimensions (length: 115mm±1mm, width: 42mm±0.5mm, thickness: 4mm) and mounting hole positions 1:1 matching factory parts. Directly aligns with left rear fender and frame bolt points—no drilling, bending, or trimming required, ensuring seamless bumper-to-fender flushness (gaps ≤1.5mm, consistent with Tesla’s factory standards).
• Heavy-Duty Durability & Anti-Corrosion: Galvanized steel base forms a primary rust barrier (prevents oxidation from road salt/water), while the black powder coating adds secondary protection against scratches and UV fading. Passes 900-hour salt spray tests (per ASTM B117) without rust, coating peeling, or discoloration—suitable for long-term use in coastal, snowy, or high-humidity regions.
• Reinforced Impact Resistance: Triangular rib structure at the bumper-fender connection point enhances load-bearing capacity (supports up to 50kg, matching OEM specs). Effectively absorbs force from minor side collisions (e.g., scraping curbs) and reduces bumper vibration during high-speed driving, avoiding outer edge sagging or deformation.
• Tool-Simple & Time-Saving Installation: Pre-drilled M8-compatible mounting holes fit Tesla’s factory hardware. Install with a standard 13mm socket, tighten bolts to 12±1 Nm (per Tesla’s official torque requirements), and complete the process in 20–25 minutes—no specialized tools or professional skills required.

3. Key Specs & Installation Tips

• Key Specifications: Material: Galvanized steel + black powder coating; Dimensions: 115mm (length) × 42mm (width) × 4mm (thickness); Tensile strength: ≥400MPa; Temperature resistance: -40°C to 140°C; Service life: ≥12 years (under normal driving conditions).
• Installation Steps: 1. Open the rear trunk, use a trim tool to carefully remove the left rear fender inner trim panel (avoid scratching the panel or body); 2. Locate the old LH bracket, detach 4 factory bolts (13mm socket) to remove it, then clean the mounting surface of rust, dust, or debris; 3. Align the new CFN LH bracket with the fender and frame bolt holes, insert bolts and tighten to 12±1 Nm; 4. Reinstall the inner trim panel, close the trunk, and check if the rear bumper’s left outer edge sits flush with the fender (adjust bolt tightness slightly if gaps are uneven).
• Critical Compatibility Note: Exclusive to 2021+ Tesla Model S—pre-2021 Model S has a revised rear bumper/fender structure and uses incompatible brackets. This is an LH-specific part; do not mix with RH (Right-Hand) outer mounting brackets (part number 1585738-00-B) as they are side-exclusive.

4. After-Sales & Bulk Support

• Warranty: 5-year warranty (covers manufacturing defects such as rust, bending, misaligned holes, or coating peeling; excludes damage from collisions, over-tightening bolts, or off-road use).
• Bulk Offers: Orders of ≥18 pieces enjoy 20% discount; bulk buyers (e.g., repair chains, dealerships) receive free technical support (including installation videos and torque verification guides) and flexible delivery schedules (support for urgent orders).
• Maintenance Tip: Inspect the bracket annually for loose bolts or coating damage—tighten bolts promptly if loose; clean the surface with a damp cloth (avoid abrasive cleaners) to remove road salt or debris, ensuring long-term anti-corrosion performance.
