The part number 7428641 (often found as the full BMW-style sequence 51117428641) refers to the Radiator Grille (Front Grill) for the Rolls-Royce Phantom VIII, produced from 2017 to present.

Unlike the Cullinan you asked about previously, the Phantom’s grille is even more integrated into the front fascia, often described as the most significant piece of “jewelry” on the car.

1. Technical Specifications

• Vehicle Compatibility: Rolls-Royce Phantom VIII (Chassis codes RR11 for Standard Wheelbase and RR12 for Extended Wheelbase).

• Material: Hand-polished stainless steel (or “Black Badge” darkened chrome, depending on the specific sub-variant).

• Design: This part number is typically associated with the main Chrome/Stainless Steel assembly.

2. Series I vs. Series II (2026 Context)

Rolls-Royce refreshed the Phantom VIII (Series II) recently.

• Series I (2017–2023): This part number (7428641) is the standard for the first iteration of the Phantom VIII.

• Series II (2024–Present): The newer version features a polished horizontal line between the Daytime Running Lights (DRLs) above the Pantheon Grille. While the main center structure is similar, the integration points and the illuminated “Glow” features of the Series II often carry newer part numbers.

3. Market Pricing & Availability

This is one of the most expensive cosmetic parts on any production vehicle.

• New OEM (Dealer): Expect a price range of $9,500 – $13,500.

• Used/Refurbished: High-quality used units (with no bent vanes or scratches) generally retail for $4,500 – $6,500.

• Shipping Warning: Because of its weight and extreme fragility (the vanes can be bent by hand pressure), shipping for this item is often quoted as $1,000+ to ensure it is crated in wood.

4. Important Installation Details

The “Spirit of Ecstasy” Housing: Note that part number 7428641 typically refers to the grille assembly itself. It does not usually include the motor-driven “Spirit of Ecstasy” retraction unit or the figurine. These are separate modules that bolt into the top of the grille frame.

Sensor Calibration: The Phantom VIII grille houses several proximity sensors and sometimes the night-vision camera. If you replace the grille, these sensors must be re-initialized by a technician with the Rolls-Royce/BMW diagnostic tool (ISTA) to ensure your Driver Assistance systems function correctly.
