Application and purpose

The suspension strut is designed for installation on the front right side of the vehicle, in the BMW 1 Series E81 120d model with the N47 engine in the M Sport version. Integrating suspension elements with braking system components allows for maintaining proper geometry, correct wheel guidance, and proper force transfer during braking and acceleration.

A unit configured in this way is particularly beneficial when replacing a damaged strut after a collision or intensive use, when the goal is to quickly restore full functionality of the front suspension without the need to assemble individual components.

Construction of the suspension and brake assembly

The presented item belongs to the Suspension replacement kits group, which means it includes key components responsible for wheel guidance, vibration damping, and cooperation with the braking system. The use of the factory BMW design guarantees a proper fit to the steering knuckle, hub, body mounts, and brake caliper, as well as compatibility with the standard operating characteristics of the M Sport chassis.

A properly selected spring and shock absorber ensure stable body support, roll control, and predictable vehicle behavior during dynamic driving. The integrated brake elements work with the factory system, which allows for maintaining even wear of discs and pads and maintaining braking efficiency in accordance with the manufacturer's specifications.

Benefits of using a complete set

Choosing a complete suspension strut with brake elements brings a number of practical service and utility benefits:

• consistency of the suspension operating characteristics on the right side with the other elements of the chassis,
• preservation of factory geometry and mounting points,
• reduction of the risk of incorrect selection of individual parts,
• acceleration of the assembly process compared to replacing scattered components.

For the user, this means more predictable handling, better control over the vehicle, and a lower risk of unwanted vibrations or noises resulting from component mismatch.

Condition, origin, and fitment

The item comes from a BMW vehicle and is part of the original M Sport configuration, which helps maintain uniform operating characteristics of the entire chassis. The product is offered as used, which allows for economical repair while utilizing the manufacturer's original design. By assigning it to a specific model and engine version, the risk of assembly problems and the need for modifications is minimized.

Additionally, the part has a dedicated OEM number and associated interchangeable numbers, which facilitates verification of compatibility with a specific vehicle configuration in service catalogs and parts selection systems.

Installation information and area of application

The strut is intended for installation on the front right side of the vehicle, in place of the factory suspension strut. Proper installation requires following BMW service procedures, including checking tightening torques, setting geometry, and verifying cooperation with the braking system after work is completed. Using a complete assembly facilitates workshop work and limits the number of potential points of error when assembling the suspension.
