BMW 1 Series E87 E87N LCI Rear Left Right Coil Spring Set A1 N/O/S

BMW 1 Series E87 E87N LCI Rear Left Right Coil Spring Set A1 N/O/S is an original suspension system component designed for installation on the rear axle of a BMW vehicle. The set includes springs for both the right and left sides, which ensures consistent suspension characteristics and stable vehicle handling. This is a solution for users looking for factory fitment and predictable vehicle behavior on the road.

Purpose and vehicle placement

The presented spring set is a rear suspension component that operates on both the right and left sides. This placement ensures even support for the body and proper cooperation with shock absorbers and other chassis components. As a result, the car maintains stability during acceleration, braking, and driving over uneven surfaces.

The springs work with components from the Shock absorber and strut mounts group, creating a cohesive system responsible for transferring loads from the body to the wheels. A properly selected set of springs is crucial for maintaining the correct suspension height, ride comfort, and predictable shock absorber performance.

Technical and functional characteristics

The rear springs in this set have been designed to operate in the demanding conditions typical for BMW vehicles. The properly selected deflection characteristics allow for:

• maintaining a stable body position under varying loads in the trunk and on the rear seat,
• effective vibration damping in cooperation with shock absorbers,
• maintaining predictable rear axle traction when driving over bumps.

As an original BMW part, the spring set is structurally matched to the suspension geometry of the specific model, which reduces the risk of incorrect installation and unwanted changes in vehicle handling. This is particularly important in cars where chassis precision and consistent steering response are essential.

Component condition and service application

The offered set belongs to the group of used parts, making it a reasonable choice for service repairs where the priority is to maintain original specifications while optimizing costs. This type of component is suitable both for replacing a single worn spring and for planned rear suspension maintenance, where replacing parts in pairs is recommended.

In workshop practice, using original BMW springs allows for reducing the risk of differences in performance characteristics between the right and left sides and avoiding suspension geometry issues after repair. This solution is particularly beneficial for users who expect consistent suspension behavior without interfering with factory settings.

Integration with the BMW suspension system

The rear springs from this set work with factory mounts, struts, and shock absorbers, allowing them to be installed in place of worn components without the need for structural modifications. Maintaining the original suspension geometry translates into:

• proper operation of safety systems dependent on wheel grip,
• even tire wear on the rear axle,
• stable vehicle handling at higher speeds.

For users who value predictability and ride comfort in BMW cars, using original springs in the rear suspension is a solution that allows maintaining the factory character of the car, without introducing changes to stiffness or suspension height.
