Application in BMW F01 LCI, F07, F10, F11, F12 models
The offered steering rack has been designed specifically for selected F-series models: the luxury F01 LCI limousine, the practical F07 Gran Turismo, and the popular F10, F11, and F12 series. As a result, the component is structurally matched to the factory steering system, which facilitates installation and helps maintain the vehicle’s original driving characteristics.
Integration with the electric power steering motor enables smooth, predictable system operation, as well as compatibility with safety systems and driver assistants provided for these BMW generations.
Construction and function of the steering rack
The steering rack integrated with the power steering motor is responsible for converting the rotary motion of the steering wheel into the linear motion of the tie rods and for appropriately amplifying the force applied by the driver. In practice, this means:
- precise vehicle handling at higher speeds,
- light steering operation during maneuvering,
- stable lane keeping,
- consistent cooperation with the vehicle’s electronics.
As an element from the Steering racks and housings group, this part is a key component of the entire system, affecting both safety and driving comfort.
Benefits of using an original BMW steering rack
Using an original BMW steering rack allows you to maintain the factory handling characteristics, which are especially important in premium class vehicles. The appropriate gear ratio, correct power steering characteristics, and compatibility with factory control systems ensure that the steering system operates in a predictable manner consistent with the manufacturer’s specifications.
The element has a dedicated OEM part number and assigned replacement numbers, which facilitates verification of compatibility with a specific equipment version and vehicle year. This allows for an informed choice of parts, minimizing the risk of installation problems.
Condition and service purpose
The offered steering rack is a used component, intended for service applications as a replacement for the factory-installed part. This is a particularly cost-effective solution for steering system repairs when it is necessary to replace the complete steering rack with the power steering motor.
Choosing an original used component allows for high installation and functional compatibility while reducing costs compared to new subassemblies.
Selecting parts by OEM number and replacement numbers
To correctly select a steering rack for a specific BMW vehicle, it is recommended to verify the OEM part number and available replacement numbers in the service documentation or by VIN. This allows for confirmation of full compatibility with the given engine version, drivetrain, and vehicle equipment.
The productand specification section contain information about the OEM part number and related reference numbers, which makes it easier to compare with data from manufacturer catalogs and service systems.
