ORIGINAL ROLLS ROYCE CULLINAN Hood Bonnet Hood NEW

For the Rolls-Royce Cullinan (RR31), the bonnet (hood) is a massive, precision-engineered aluminum panel. In 2026, sourcing an “Original New” hood requires careful attention to the Series II facelift updates, as the front-end geometry has been subtly revised for better aerodynamic flow and cooling.

1. Core Part Numbers (2018–2026)

The hood is typically supplied primed (bare aluminum) from the factory.

• New “Take-off” Units: You can often find “take-off” hoods (removed from new cars for carbon fiber upgrades) for approximately These are genuine factory-painted units, often in Diamond Black (R19) or Arctic White.

2. Technical Specifications

The Cullinan hood is part of the “Architecture of Luxury” all-aluminum spaceframe.

• Material: Lightweight, high-tensile 6000-series aluminum.

• Spirit of Ecstasy Integration: The front leading edge features a reinforced cutout specifically for the Mascot Retraction Mechanism. Note that the mechanism itself is usually sold separately.

• Sound Insulation: A genuine new hood should be fitted with the factory acoustic dampening liner to maintain the cabin’s “Library Quiet” atmosphere.

3. Series II vs. Series I Differences

If you are buying for a 2025 or 2026 model, ensure you get the Series II spec:

• Front Leading Edge: The Series II hood is designed to sit flush with the new Illuminated Pantheon Grille, which has a slightly lower and more “V-shaped” profile than the original.

• Shut Lines: The precision required for the 3.5mm gap is achieved through updated hinge mounting points on the newer 41005A75901 part.

4. Sourcing Options (2026)

1. Authorized Dealer: The only way to get a “Brand New” factory-crated unit. Lead times can be 4–6 weeks as they are often shipped from the Goodwood facility.

2. Specialized Vendors: Companies like Miller Motorcars or Scuderia Car Parts hold stock of genuine OEM panels.

3. Aftermarket Carbon Fiber: If you want an upgrade rather than a standard replacement, DMC and Mansory offer Forged Carbon Fiber hoods for the Cullinan, retailing between 

5. Installation & Calibration

• The “Spirit” Alignment: After installing a new hood, the Spirit of Ecstasy retraction system must be recalibrated. If the hood is even $1\text{mm}$ out of alignment, the mascot may snag on the hood opening during its deployment/retraction sequence.

• Paint Depth: Rolls-Royce factory paint averages 150–200 microns in depth. If painting a primed hood, ensure your body shop uses a high-solids clear coat to match the “mirror finish” of the surrounding fenders.
