Purpose and function of the component

The rear right bumper crash bar / shock absorber is a key structural element in the rear body area of the BMW X4 G02 / F98. Its tasks include:

• absorbing and dissipating impact energy in the rear zone,
• ensuring stable mounting of the rear bumper on the right side,
• maintaining the correct geometry of connections between the bumper and the supporting structure,
• limiting the transfer of loads to other body components.

Thanks to its precise fit for the specific X4 generation, the absorber works with factory mounting points and retains the original deformation characteristics in the event of a collision.

Construction and fitment for BMW X4 G02 / F98

The offered component has been designed specifically for use in the rear right side of the vehicle, which eliminates the need for any modifications or adaptations. The crash bar construction is optimized for:

• longitudinal and transverse stiffness,
• cooperation with the bumper beam and other reinforcements,
• proper distribution of forces in the impact zone.

As an original BMW component from the Bumpers and reinforcements group, the part maintains factory dimensional tolerances, which facilitates installation and reduces the time required for fitting in a body and paint shop.

Condition, origin, and benefits of using a used part

The element comes from dismantling and is offered as a used part, which is a cost-effective solution while maintaining the manufacturer's original specifications. In practice, this means:

• factory geometry and mounting points consistent with the BMW X4 G02 / F98 body,
• preservation of the designed operating characteristics in the crumple zone,
• the possibility of an economical post-accident repair without compromises in terms of fitment.

Using an original rear right bumper reinforcement allows for restoring the correct operation of the impact zone and aesthetic alignment of the bumper with the bodywork.

Installation in the rear right zone

The crash bar is intended for installation in the rear – right side of the vehicle area, in accordance with the factory design layout of the BMW X4 G02 / F98. When replacing, it is recommended to:

• verify the condition of the mounting points on the body,
