Rear Left Air Spring for Porsche Macan
Arnott A-3945 is an aftermarket rear left air suspension spring for the 2015-2018 Porsche Macan (95B chassis) with auto leveling. It uses a multi-ply Continental ContiTech air sleeve and a rubber convoluted bellows to restore rear suspension support and ride height control.
The Arnott NEW product line focuses on replacement suspension components built for direct-fit service. This A-3945 assembly is made in the USA and includes a CNC-machined aluminum top and piston, heavy-duty crimping rings, a protective dust cover, and a new 6 mm air line fitting for faster installation.

Arnott A-3945 is used to replace a worn or leaking rear left air spring on Porsche Macan models with auto leveling. It is a direct replacement for the rear suspension air spring assembly and is built to match the original mounting style with a stud upper mount and base cup lower mount. This part cross-references Porsche OE numbers such as 95B616001A and 95B616001B for the same application.
- Rear ride height sits lower than normal
- Air suspension leak causes the vehicle to sag after parking
- Uneven rear stance on a Porsche Macan
- Compressor runs more often due to loss of air pressure
- Rear suspension warning messages related to leveling performance
Installation notes: verify rear left placement before removal, inspect the air line and surrounding suspension components for wear, and replace air springs in pairs as Arnott recommends. Confirm the vehicle is equipped with auto leveling and match the OE-style upper and lower mounts during installation. The 6 mm air line fitting supports a straightforward connection to the existing air system.
Quality assurance: Arnott manufactures this air spring in the USA using a Continental ContiTech air sleeve, heavy-duty crimping rings, and CNC-machined aluminum components for consistent fit and function.
