For the Rolls-Royce Cullinan (RR31), the front bumper is one of the most complex exterior assemblies in the Rolls-Royce catalog. In 2026, it is crucial to verify whether you are looking for the Series I (2018–2024) original design or the Series II (2025+) facelift version, as they are not directly interchangeable without a full front-end conversion.

1. Core Part Identification

The RR31 front bumper is a modular system. The main “cover” is the painted shell, but the “bumper” typically includes the following core part numbers:

2. Series I vs. Series II (Facelift)

If you are sourcing a replacement in 2026, the visual differences are significant:

• Series I (2018–2024): Features a more traditional, “blocky” design. The air intakes are horizontal, and the bumper line remains relatively flat across the face.

• Series II (2025+): Features the new “V-shape” yacht-inspired bow line. It has tall, vertical LED Daytime Running Light (DRL) cutouts on the outer edges and a simplified, monolithic lower intake.

3. Trim Variations

• Standard Trim: Characterized by polished stainless steel or chrome “widened veins” in the air intakes and a silver-finish lower center plate.

• Black Badge: The bumper features High-Gloss Black chrome accents. Additionally, the lower valance and side sills are typically painted in the body color (e.g., Tempest Grey) rather than textured black, creating a more lowered, aggressive stance.

4. Component Checklist

A “Complete” bumper assembly for the Cullinan must accommodate a high density of technology. Ensure the following are included or transferred:

• Active Grille Shutters: Behind the lower intakes for thermal management.

• Sensors: 6x Ultrasonic PDC sensors and the long-range ACC Radar (Adaptive Cruise Control).

• Camera System: Mountings for the front-view and night-vision cameras (if equipped).

• Headlight Washers: Internal telescopic nozzles (Part of the “Headlamp Cleaning System” option).
