As an element from the Steering Racks and Housings category, the product works with the steering column, tie rods, and other system components, creating a cohesive system responsible for the safety and predictability of the car's behavior on the road. Its original Mercedes origin promotes the maintenance of correct geometry and compatibility with the vehicle's factory electronics.

Purpose and Application in Mercedes W177

This electric steering rack has been specifically designed for the W177 platform, meaning it fits factory mounting points and works with the safety systems and driver assistance features intended for this model. This allows for the preservation of original handling parameters without the need for modifications to the body structure or suspension system.

Replacing the steering rack with an original part from the same family helps reduce the risk of incorrect power steering operation, steering wheel play, or uneven wheel response to steering inputs. This is particularly important in vehicles equipped with advanced traction control and stability systems, which require seamless integration with the steering system.
