BMW Z4 E85 Sachs Rear Left Right N/O/S Shock Absorber Spring Strut Set 312 468

BMW Z4 E85 Sachs Rear Left Right N/O/S Shock Absorber Spring Strut Set is a complete, used suspension strut designed for the rear axle, prepared for installation on both the left and right sides. The set provides a solid foundation for restoring the proper operation of the suspension in a BMW Z4 E85 roadster, ensuring stable handling and predictable vehicle behavior. Thanks to the shock absorber and strut design, the set allows for a consistent replacement of the components responsible for vibration damping and spring support.

Purpose and vehicle placement

The presented set of suspension struts is designed for use on the rear axle of the BMW Z4 E85, with the possibility of installation on both the left and right sides. This solution facilitates the servicing of the entire axle – one pair of components covers the full range of replacement within the rear of the vehicle, which promotes uniform damping characteristics and consistent suspension performance.

Placement on the vehicle includes:

• the rear part of the body,
• the left side,
• the right side.

This makes the set particularly useful for comprehensive suspension maintenance when it is necessary to replace both struts on the axle simultaneously.

Construction of the shock absorber and strut set

The set belongs to the Shock Absorbers and Struts category, meaning it combines the function of vibration damping with the mechanical structure of supporting the suspension spring. This configuration allows for precise wheel guidance, control of suspension deflection, and stable transfer of loads from the body to the chassis.

The combination of the shock absorber and strut:

• ensures rigid mounting in the body and steering knuckle,
• facilitates maintaining suspension geometry within acceptable tolerances,
• reduces excessive body roll during braking, acceleration, and driving over uneven surfaces.

An element configured in this way is crucial for maintaining the predictable traction and driving comfort characteristic of the BMW Z4 E85.

Performance characteristics and service application

As a used set of shock absorber and strut, the product is a practical solution in situations where an element with factory geometry and operating parameters is sought, while maintaining a reasonable service budget. The set will prove useful for, among other things:

• post-accident repairs of the rear suspension,
• replacing worn or leaking shock absorbers,
• restoring the original handling characteristics after previous modifications.

A suspension strut of this type helps to limit phenomena such as excessive rear-end squat, instability during load changes, and unwanted body vibrations. As a result, the driver receives more predictable vehicle behavior in corners and during high-speed driving.

Brand, compatibility, and technical aspects

The product is marked as Unbranded, which in practice means that it is not signed with the vehicle manufacturer's logo, but remains functionally matched to the design of the BMW Z4 E85. The use of appropriate part numbers and interchangeable numbers (visible in the technical specification) facilitates the verification of compatibility with a specific model version.

Before installation, a standard service procedure is recommended, including checking mounting points, associated components (bump stops, dust covers, spring mounts), and suspension geometry after the work is completed. This approach allows for fully utilizing the potential of the set and reducing the risk of premature wear of other components.
