This rear bumper lower section (part number 1609582-00-A) is an OEM-matching structural component exclusively engineered for 2021 and later Tesla Model X vehicles, precisely fitting the rear bumper’s lower contour—integrating a dedicated towing hook opening to align with the Model X’s factory towing system layout. Its core functions span structural support, protection, and functional compatibility: first, it reinforces the rear bumper’s lower rigidity, preventing deformation from minor rear impacts (e.g., reversing into a low parking block) and maintaining the bumper’s sleek factory shape; second, it acts as a barrier for the rear underbody, blocking road debris (gravel, mud), rainwater, and road salt from splashing into the rear chassis area—avoiding corrosion of towing hardware, rear suspension components, and wiring harnesses; third, the pre-integrated towing hook opening provides easy access to the Model X’s hidden towing hook (no need to cut or modify the bumper), ensuring compliance with emergency towing needs while preserving the rear-end’s unbroken visual aesthetics.

Crafted from OEM-grade TPO (Thermoplastic Olefin) with 15% glass fiber reinforcement, the bumper lower section balances durability and flexibility. The reinforced TPO material resists impact from low-speed collisions (tensile strength ≥280MPa) without cracking, and withstands extreme environmental conditions: it passes 720-hour salt spray tests (ASTM B117) to resist corrosion from coastal salt air or road salt, endures -40°C to 85°C temperature fluctuations (suitable for snowy winters or high-heat summers), and resists UV fading (500-hour ASTM G154 UV tests) to maintain long-term color consistency with the rear bumper. The surface features a matte black textured finish that matches the Model X’s factory rear trim, avoiding visual inconsistency.

Installation adheres to Tesla’s 2021+ Model X service guidelines, taking 40–50 minutes with standard tools (10mm socket, trim tool, jack stands): 1. Lift the vehicle’s rear end and secure it with jack stands (ensure stable support); 2. Use a trim tool to gently detach the rear underbody splash guard and disconnect the rear parking sensor wiring (if attached to the old bumper section); 3. Locate the old lower section, remove 8 factory bolts (10mm socket) and 6 plastic snap clips to remove the worn part; 4. Clean the mounting surface to eliminate dust, debris, or residual adhesive; 5. Align the CFN bumper section with the rear bumper’s upper frame, snap clips into place, and tighten bolts to 6±0.5 Nm (per Tesla torque specs); 6. Reconnect the parking sensor wiring (if applicable), reinstall the underbody splash guard, and lower the vehicle to check for a gap-free fit with the upper bumper.

After-sales support includes a 3-year warranty (covering manufacturing defects such as cracked material, misaligned mounting holes, or damaged towing hook opening edges; excluding collision damage or improper installation) and protective packaging: 1 piece per pack (wrapped in anti-scratch film + thick foam + hard carton) to prevent surface scratches or deformation during transport. For repair shops or Tesla service centers, bulk packs (10 pieces/box) are available, ensuring consistent quality for every 2021+ Model X rear bumper lower section replacement. This component is essential for maintaining the rear bumper’s structural integrity, towing functionality, and the Model X’s premium rear-end appearance.
