Whether you are performing a conversion from a GT 43/53 or replacing a damaged GT 63 unit, this bumper ensures the aggressive “widened” stance and thermal management necessary for the 4.0L Biturbo V8.

Aerodynamic & Design Features

• High-Gloss Black Diffuser: A multi-finned center element designed to accelerate airflow under the vehicle, creating a low-pressure zone for increased stability.

• Aggressive Air Outlets: Functional side vents that extract hot air from the rear wheel arches and exhaust system.

• Quad Exhaust Integration: Precision-molded for the signature AMG trapezoidal twin-tailpipe trims.

• Aerodynamic Flics: Provisions for the lateral flics (canards) that further optimize airflow separation at the rear corners.

Technical Compatibility

*Note for GT 43/53 Owners: Upgrading to the GT 63 rear bumper requires the matching GT 63 exhaust tips and potentially modified inner wheel arch liners to accommodate the wider diffuser profile.

Material & Condition

• Construction: High-impact OEM Polypropylene (PP-EPDM), engineered to withstand high temperatures from the exhaust system.

• Finish: Available in factory primer (ready for paint) or as a high-quality “Take-Off” in original Mercedes-Benz colors.

• Sensors: Fully compatible with 6-PDC sensors, Rear-Cross Traffic Alert, and the hands-free trunk access (kick sensor).

Why Choose Genuine X290 Aero Parts?

The X290 is one of the most aerodynamically sensitive vehicles in the AMG fleet. Using a Genuine A290 Rear Bumper guarantees that the diffuser fins are angled precisely to the millimeter, maintaining the balance between front and rear downforce. Unlike aftermarket replicas, this OEM unit features internal heat shielding to prevent the bumper skin from warping or melting due to the extreme heat generated by the 63 S exhaust.
