Product Specifications

Aston Martin DBX Rear Bumper Reinforcement

The MY8317758A rear carrier forms part of the DBX rear bumper structure. Current European parts catalogues identify it as a rear bumper reinforcement/beam, while current used-parts listings describe it as a genuine Aston Martin rear bumper reinforcement impact bar.

This makes it a suitable replacement component for a DBX that has sustained rear-end collision damage or requires replacement of the original bumper reinforcement during body repair.

OEM Part Number

The main identification number is:

MY8317758A

You may also encounter the part written in hyphenated format as:

MY83-17758-A

Some current listings additionally cross-reference MY8317758AC / MY83-17758-AC, so the exact suffix should be checked before purchasing.

Application & Compatibility

Current listings identify MY8317758A with the Aston Martin DBX rear bumper reinforcement. One current listing specifically identifies the part as suitable for DBX models from 2019 onward, while another lists compatibility across DBX model years 2019–2026.

Because bumper structures can vary by production specification, model year and revision, buyers should verify the VIN, existing OEM number and physical mounting configuration before installation.

Replacement Use

This rear bumper reinforcement is appropriate for:

• Rear accident repairs
• Replacement of a bent bumper reinforcement
• Collision-damaged DBX restoration
• Rear bumper structural repairs
• OEM bodywork replacement
• Aston Martin specialist repairs
• DBX restoration projects
• Replacement of damaged original hardware

A damaged reinforcement should be inspected carefully before reuse. If the vehicle has been involved in a collision, the surrounding mounting points and rear body structure should also be checked by a qualified repairer.

Condition

The condition of the specific part should be confirmed from the supplied photographs and listing information.

For a used reinforcement, inspect the beam for:

• Bends or deformation
• Impact marks
• Cracks
• Corrosion
• Damaged mounting points
• Missing hardware
• Previous repair or modification

The part number should remain clearly identifiable before installation.

Installation

Installation should be carried out by a qualified automotive body repair specialist familiar with Aston Martin vehicles.

The original bumper assembly normally needs to be removed to access the reinforcement. Before fitting, compare the replacement component with the original for part-number accuracy, mounting points, shape and overall configuration.

Buyer Verification

Before ordering, provide the seller with the vehicle’s:

• VIN/chassis number
• Model year
• Exact DBX variant
• Existing bumper reinforcement part number
• Photographs of the original component where possible

This is particularly important because MY8317758A and MY8317758AC appear in current listings as related references. Confirm which revision is required for your specific vehicle.
