Aston Martin DB11 rear bumper/valance HY5317E955AK

piece that houses the exhaust tips and often integrates with the rear diffuser. Because the DB11 is sold globally, the suffix (“AK”) is critical for matching your specific market and trim level.

Technical Specifications

• Application: Aston Martin DB11 (V8 and V12 models, approx. 2017–2024).

• Type: Rear Bumper Insert / Valance Panel.

• Material: High-grade composite/plastic (often finished in Gloss Black or Graphite).

• Market Variant: The “AK” suffix typically corresponds to the ROW (Rest of World) or European specification, which differs from the “FED” (US/Canada) version primarily in the reflectors and the size of the license plate aperture.

Suffix Variants (Compatibility Check)

If you are sourcing this part, ensure the suffix matches your car’s original trim. The center assembly remains the same, but the finish varies:

• AK / AL: Often the standard “ROW” (Rest of World) spec in black or textured finish.

• DL: Typically the FED (North American) spec with specific reflector cutouts.

• GL: Often signifies a specific Black Pack or Gloss Black painted finish.

Common Issues & Replacement

1. Exhaust Heat: Because the exhaust tips sit directly within the cutouts of this valance, poor alignment of the mufflers can lead to “heat warping” or melting of the plastic around the edges.

2. Reverse Sensor Integration: This panel houses the rear PDC (Parking Distance Control) sensors. When replacing the unit, you must carefully swap the sensors and their silicone gaskets to avoid “false alarm” beeps.

3. The “Third Brake Light”: On some DB11 variants, a F1-style central rain light or reflector is integrated into this lower valance. Ensure the wiring harness is disconnected before pulling the panel away from the main bumper.

Installation Note

This valance is held in place by a series of T20/T30 Torx screws along the bottom and heavy-duty plastic clips along the top edge where it meets the main bumper skin.

Pro-Tip: Removing this part is significantly easier if the car is on a lift. If you are doing this on the ground, you will likely need to remove the rear wheel arch liners to reach the “hidden” clips on the far left and right corners.
