Purpose and vehicle placement

The spring set is dedicated to the rear axle of the vehicle and can be installed on both the left and right sides. This solution facilitates service – the set allows for the simultaneous replacement of both components, which helps maintain balanced suspension operation and consistent vehicle reactions during acceleration, braking, and cornering.

Operating characteristics and benefits of installation

Springs from the Leaf and coil springs category are responsible for transferring loads between the body and the wheels, as well as maintaining the correct vehicle height. The use of original geometry and stiffness translates into:

• maintaining factory comfort in damping road irregularities,
• stable handling at higher speeds,
• proper cooperation with safety systems (ABS, ESP),
• even load distribution on other suspension components.

As a result, the car retains predictable reactions, and the driver receives consistent, repeatable handling feedback, which is essential both in daily use and when the vehicle is under heavier loads.

Professional selection and installation

The set of rear left and right springs allows for service to be performed in accordance with best workshop practices – replacing them in pairs minimizes the risk of differences in deflection and reduces uneven wear of tires and mating components. For optimal results, installation in a workshop environment is recommended, with a suspension geometry check upon completion. This approach promotes maintaining driving stability and proper steering system operation.

Why choose an original Audi solution

Components prepared for a specific model platform are designed taking into account the vehicle's weight, load distribution, and shock absorber characteristics. In practice, this means:

• secure fitment to the rear axle mounting points,
• no need to modify other suspension components,
• consistency with factory chassis settings.

For users who want to keep their car in a configuration close to the original, this choice is a technically safe and predictable solution for long-term operation.

Used OEM component vs. service cost optimization

Choosing a used OEM component allows you to significantly reduce repair costs while maintaining a design consistent with the manufacturer's specifications. This solution is particularly beneficial for comprehensive suspension maintenance, where several components are replaced at the same time.
