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.
