Lower Rear Bumper Cover with Textured Surface for 2021+ Tesla Model X | 1609584-00-A (CFN Brand)

1. Underbody Protection: Acts as a durable barrier for the rear underbody, blocking road debris (gravel, mud), rainwater, and road salt from splashing into the rear chassis area—avoiding corrosion of rear suspension hardware, wiring harnesses, and hidden towing components.
2. Structural Support: Reinforces the rear bumper’s lower edge rigidity, preventing deformation from minor rear impacts (e.g., reversing into low parking blocks or curbs) and maintaining the bumper’s sleek factory shape over long-term use.
3. Visual & Functional Coherence: The integrated textured surface matches the Model X’s original rear trim texture, eliminating visual inconsistencies that aftermarket smooth-surface covers often cause; it also fits seamlessly with adjacent components (e.g., rear underbody splash guards, exhaust trim) to preserve the vehicle’s premium rear-end appearance.

• Weather Resistance: Endures -40°C to 85°C temperature fluctuations, suitable for snowy winters, coastal high-humidity areas, or high-heat summers.
• Corrosion & UV Resistance: Passes 720-hour salt spray tests (ASTM B117) to resist rust from road salt or coastal air, and 500-hour ASTM G154 UV tests to prevent fading—ensuring long-term color and texture consistency with the original rear bumper.
• Textured Surface Durability: The matte textured finish resists scratches from small debris (e.g., kicked-up stones) and maintains its tactile feel even after repeated car washes.

1. Lift the vehicle’s rear end and secure it with jack stands (ensure stable support to avoid safety risks).
2. Use a trim tool to gently detach the rear underbody splash guard and disconnect the rear parking sensor wiring (if the sensor is mounted on the old bumper cover).
3. Locate the old lower rear bumper cover, remove 7 factory bolts (10mm socket) and 5 plastic snap clips to detach the worn part.
4. Clean the mounting surface with a dry cloth to eliminate dust, debris, or residual adhesive—ensuring a tight fit for the new cover.
5. Align the CFN bumper cover with the rear bumper’s upper frame, snap the plastic clips into place, and tighten the bolts to 6±0.5 Nm (per Tesla’s official torque specifications).
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 and adjacent trim.
