Lamborghini Huracan Door Right 4T0831435B Bianco Icarus

the part number 4T0831435B refers to the Right-Hand (Passenger side for LHD) Door Shell for the Lamborghini Huracán.

Searching for this part specifically in Bianco Icarus (LY9K) typically points toward the secondary market (take-offs or salvage), as new factory replacements from Lamborghini are delivered in a primer finish.

1. Technical Identification

• Part Number: 4T0831435B (Door Shell Only).

• Material: Lightweight Aluminum (specific to the Huracán spaceframe).

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

• Compatibility: This shell is compatible with the LP610-4, LP580-2, and Huracán Evo models. While the external skin is identical, internal electronics (Harness/Sensors) may vary by model year.

2. 2026 Market Pricing (Estimated USD)

Aluminum body panels for exotics carry a premium due to their “one-time use” nature in collisions (aluminum is difficult to reshape compared to steel).

3. The “Bianco Icarus” Paint Match

• The Flake Factor: Bianco Icarus is a metallic white. Finding a door already painted in this color saves significant money, but be aware that the metallic flake “lay” can vary between production batches.

• Weathering: A door from a 2016 model may have slightly different paint saturation than a 2024 Evo due to UV exposure.

• Professional Tip: Even with a pre-painted door, a high-end body shop will usually recommend “blending” the front fender and rear quarter panel to ensure the metallic transition is invisible.

4. Critical Installation Notes

• Hinges & Alignment: If the door is being replaced due to an accident, the Upper and Lower Hinges (4T0831402) should be inspected for even a $1\text{mm}$ bend. Aluminum doors are notoriously difficult to align if the hinges are compromised.

• Component Swap: If you buy the shell (4T0831435B), you will need to swap over your:

  • Window Regulator and Motor.

  • Side Mirror Assembly.

  • Electronic Control Module (Door ECU).

  • Soft-Close/Latch Mechanism.

• Airbag Sensors: The Huracán uses pressure-sensitive sensors inside the door for side-impact airbag deployment. These must be handled with care and often require a dealer-level diagnostic tool to clear any fault codes after the swap.
