Product Details

Arnott AS-3129 is engineered for the rear right suspension corner on the 2003-2018 Bentley Continental, the 2013-2019 Bentley Flying Spur, and the 2004-2006 Volkswagen Phaeton. The strut uses a custom-tuned Eibach damper to balance comfort and response, while the elongated piston helps deliver consistent suspension travel without requiring the OE reservoir. The construction combines an air sleeve, protective aluminum can, and precision-machined upper mount for a direct-fit replacement solution.

This part cross-references Bentley and Volkswagen OE numbers for the same application, including 3W0616002 and 3D0616002D.

Common Problems This Part Can Address

• Rear suspension sag on the passenger side
• Air leaks from a worn air sleeve or bladder
