Application and function in the suspension

The presented Mercedes W415 Rear Air Suspension Spring Strut Set Left Right operates on the rear axle, on both the left and right sides, responsible for maintaining the specified vehicle height and proper suspension characteristics. These components work in conjunction with the suspension control system, absorbing vertical loads and damping road irregularities.

Thanks to properly functioning air springs, the rear part of the vehicle maintains stable geometry, which translates into predictable handling, even tire wear, and correct operation of safety systems. The set is dedicated to Mercedes W415 series vehicles equipped with rear-axle air suspension.

Construction and operating characteristics

The set includes two elements working symmetrically on both sides of the rear axle. Each of them acts as a resilient suspension element, replacing classic steel springs. The pneumatic solution allows for more precise adjustment of suspension stiffness to the current vehicle load, which is particularly important with variable trunk loads or when carrying passengers in the back seat.

A properly selected set of air springs ensures:

• maintaining the specified rear body height across a wide range of loads,
• stable vehicle handling during braking and acceleration,
• more even distribution of forces on suspension components and the body,
• reduction of body roll during dynamic maneuvers.

Benefits of using an original Mercedes solution

Using a set dedicated to a specific vehicle series allows for maintaining the factory suspension operating characteristics. Proper fitment to the rear axle geometry minimizes the risk of incorrect body positioning, thereby reducing the need for additional modifications. This is particularly important in vehicles equipped with driver assistance systems that rely on the correct body position relative to the road.

Components from the Leaf springs and coil springs group have a key impact on ride comfort, which is why it is worth using components that are structurally consistent with factory solutions when replacing them. In the case of air suspension, this translates into predictable vehicle behavior both during city driving and on longer routes.

Condition, selection, and installation

The offered set is N/O/S (New Old Stock) and is intended for users looking for parts with proven compatibility with a specific vehicle series. Before installation, it is recommended to verify compatibility with your model and check the pneumatic system for line leaks and proper equipment operation.

When replacing air springs on the rear axle, it is worth:

• performing the replacement in pairs to maintain symmetrical suspension characteristics,
• checking the condition of mounts and mating components,
• performing an adaptation or calibration of the suspension height after installation, if required by the system.

Expanding Mercedes suspension upgrades

If you are planning a comprehensive repair or upgrade of the rear axle suspension zone in your Mercedes and need other elements from the same group, such as additional springs, leaf springs, or mating components, check the available parts in the Mercedes Leaf springs and coil springs category.
