Purpose and function of the component

The rear right underbody shield has been designed specifically for the X156 body type, taking into account the characteristic construction of the rear underbody. Its placement in the rear right area allows for:

• protection of a section of the structural frame and components mounted in this zone,
• limiting the direct impact of water, mud, and road debris,
• stabilizing airflow under the vehicle at higher speeds.

Thanks to its fitment for the specific body model, the shield works in conjunction with adjacent body components, creating a cohesive system that protects the rear underbody.

Construction and body fitment

The component belongs to the Bumpers and reinforcements group, which means its geometry is linked to the rear bumper line and the construction of reinforcements in this zone. The shape and mounting points are prepared for factory brackets on the body, which facilitates installation and allows for maintaining proper alignment with other shields.

Placement on the vehicle in the rear right underbody section requires precise fitment – the original construction ensures proper adhesion to the bodywork and minimizes the risk of looseness or unwanted vibrations while driving.

Benefits of using an original shield

Using an original underbody shield in the rear right section provides a number of practical operational benefits:

• Better underbody protection – limiting contact of sensitive zones with water, road salt, and small stones.
• Stable airflow – maintaining the airflow under the car as intended by the manufacturer, which promotes predictable vehicle behavior.
• Structural consistency – matching factory mounting points and adjacent body components.
• Easier diagnostics and service – maintaining the original shield layout makes it easier for mechanics to access and identify underbody zones.

Condition and service application

The item is in used condition, making it a reasonable choice for post-accident repairs, replacing missing shields, or restoring the completeness of the underbody after previous interventions. It works well both in routine repairs and in more extensive service work, where it is important to restore the factory underbody protection system.
