Rolls Royce Cullinan Grille Grille Radiator 7448950

For the Rolls-Royce Cullinan (RR31), the part number 7448950 (full OEM part number 51137448950) refers to the Front Radiator Grille Assembly.

This is the quintessential “Pantheon” grille for the Series I Cullinan (2018–2024). It is a massive, hand-finished component that defines the vehicle’s front profile.

1. Component Breakdown

A complete 7448950 assembly typically includes:

• The Outer Shell (Housing): The heavy, high-polished stainless steel frame.

• The Waterfall Vanes: The vertical slats that are meticulously aligned.

• Night Vision Cutout: This specific part number is designed to accommodate the Night Vision with Human Recognition camera (if equipped), usually positioned behind a specialized section of the vanes.

2. Finishes & Variations

While the part number generally refers to the High-Gloss Chrome (Stainless Steel) version, there are distinct versions for different trim levels:

• Standard Chrome: The most common finish, highly reflective and traditional.

• Black Badge (Dark Chrome): Often carries a different internal suffix. The “Black Badge” version uses a dark electrolyte finish that looks like liquid obsidian.

• Satin Finish: A rare, brushed metallic look found on certain Bespoke commissions.

4. Technical Compatibility & Installation

• Series I vs. Series II: This part (51137448950) is for the Series I (2018–2024). It will not fit the Series II (2025/2026 Facelift) bumper and headlights without a complete front-end swap.

• Mascot Retraction: The grille is the housing for the Spirit of Ecstasy retraction mechanism. When replacing the grille, you must carefully transfer the electric motor assembly (Part No. 51117347492).

• Airflow: Behind this decorative grille are the Active Grille Shutters. Ensure they are not obstructed by the new grille frame, as this will trigger an engine cooling fault.

5. Important Verification

If you are buying this part used, inspect the “Vanes” (slats) carefully. Because they are hand-set, any slight misalignment is highly visible to the naked eye. Also, verify if the listing includes the RR Badge (Plinth), as this is often sold as a separate, restricted part.
