Lamborghini Huracan Door Left 4T0831436B Bianco Icarus

the part number 4T0831436B refers to the Left-Hand (Driver side for LHD) Door Shell for the Lamborghini Huracán. Sourcing this specifically in Bianco Icarus (LY9K) usually means looking for a “New Take-off” or a high-quality used part, as factory-new shells are typically shipped in primer.

1. Technical Identification

• Part Number: 4T0831436B (Shell Only).

• Material: Lightweight Aluminum.

• Color Code: LY9K (Bianco Icarus / Metallic White).

• Compatibility: This shell fits the majority of the Huracán range, including the LP610-4, LP580-2, and the Evo.

  • Note: The internal wiring harness and window glass may differ between early LP models and the later Evo/STO models, but the metal shell itself remains consistent.

3. Installation & Paint Considerations

• The “Metallic” Challenge: Bianco Icarus is a metallic paint (LY9K). Even if you find a door in the “correct” color, the metallic flake orientation and slight fading on your car may not match perfectly. Professional blending into the front fender and rear quarter panel is usually required.

• Weight & Hardware: The door is surprisingly light, but the hinges (4T0831401) are high-strength steel. If the door was damaged in a collision, the hinges are often bent and must be replaced to ensure the door flush-mounts correctly to the chassis.

• Transfer of Components: If you are buying just the shell (4T0831436B), you will need to transfer your existing:

  • Side Mirror Assembly.

  • Soft-Close/Latch Mechanism.

  • Window Regulator and Glass.

  • Interior Door Card.

4. Safety Warning (Hinge Sensors)

The Huracán uses specialized sensors within the door cavity for side-impact airbag deployment. When swapping doors, the electronic control unit (ECU) may require a “reset” or “re-coding” to recognize the door’s electronics, particularly if the donor door is from a different model year.
