Rolls Royce Cullinan bonnet

For the Rolls-Royce Cullinan (RR31), the bonnet (hood) is a substantial aluminum panel designed with precise tolerances for the Spirit of Ecstasy housing and the signature “V” lines. In 2026, the market is split between original Series I (2018–2024) parts and the newer Series II (2025–2026) components.

1. Genuine Part Numbers & Pricing

The Cullinan bonnet is typically supplied in a primed state. If you are looking for a painted “take-off” unit, prices vary based on the rarity of the color.

2. Technical Features & Requirements

• Material: 100% lightweight aluminum. It is extremely difficult to “dent pull” or repair due to the metal’s memory; insurance standards almost always dictate a full replacement.

• The Mascot Housing: The bonnet features a dedicated aperture for the Spirit of Ecstasy mechanism. If your vehicle is the Black Badge, ensure your plinth and mascot are switched to the darkened chrome version (Part No. 51145A38459).

• Pedestrian Protection: The Cullinan uses pyrotechnic actuators (51237419771) that fire to lift the rear of the bonnet in the event of a pedestrian impact. These are single-use items and must be replaced if the vehicle was in a front-end collision.

3. Market Availability in 2026

1. New OEM: Usually available within 1–2 weeks from the Goodwood facility or major distributors.

2. Take-offs: High-end tuning shops (e.g., Mansory, Novitec) often sell “as-new” factory bonnets removed from cars receiving carbon fiber widebody kits. These are often available in Diamond Black (R19) or Arctic White for roughly

3. Used/Recycled: Prices for used bonnets with minor blemishes range from

4. Installation & Alignment

The “Magic Carpet Ride” ethos extends to the bodywork.

• Tolerance: The factory gap (shut-line) between the bonnet and the front fenders should be exactly 3.5mm.

• Software: If your Cullinan has the Series II Illuminated Grille, the bonnet sensor may need to be recalibrated via the vehicle’s control module to ensure the lighting sequence is not interrupted when the latch is engaged.
