Product Details

Arnott AS-2891 is engineered for rear air ride suspension service on Jaguar X350 and X358 chassis vehicles with Sport Suspension. The design replaces common OE weak points such as upper seal leakage, noisy upper mount operation, and lower rubber seal wear. Its hydraulic internal damper and progressive spring rate help maintain responsive rear suspension control, while the new air bladder and sealing components support consistent air suspension performance. This part cross-references Jaguar OE numbers such as C2C2261 and C2C20165 for the same application.
