Arnott MR-3447 Suspension Shock Absorber - Rear Right

Arnott MR-3447 Rear Right Magnetic Ride Shock

Arnott MR-3447 is an OES rear right magnetic ride shock for select Cadillac DTS and Buick Lucerne applications with GM magnetorheological damping. It restores the adaptive ride control behavior expected from the factory system while connecting to the vehicle ECU with no modifications.

Built as a monotube damper, this Arnott NEW line shock uses magnetorheological fluid and electromagnetic coils to adjust damping response in real time. That makes MR-3447 a direct-fit solution for drivers searching for a rear right magnetic ride shock for 2009-2015 Cadillac DTS or a rear right Magneride shock for 2006-2011 Buick Lucerne.

Key Features

• OES rear right magnetic ride shock for GM magnetorheological damper systems
• Monotube design with magnetorheological fluid for adaptive damping response
• Electromagnetic coil control changes fluid viscosity and suspension stiffness instantly
• Connects to the vehicle ECU with no modifications
• Arnott NEW product line replacement for factory-style ride control
• Part number MR-3447 for fitment-based search and ordering

Detailed Description

MR-3447 is engineered for vehicles equipped with the GM Z95 RPO magnetic ride system, delivering the same type of electronically controlled damping used by the original equipment setup. The shock’s internal fluid contains iron particles that respond to magnetic fields, allowing the suspension to vary firmness as road conditions change. This makes it a practical replacement for owners needing a Cadillac DTS rear right magnetic ride shock or a Buick Lucerne rear right Magneride shock that retains factory electronic communication.

This part cross-references Cadillac 15211376 and 19302769 for the same application. Arnott MR-3447 is a focused replacement for the rear right position on the listed vehicles, with fitment centered on factory magnetic ride configurations.

What It Helps Address

• Rear suspension ride quality that has become harsh or inconsistent
• Electronic damping faults tied to the magnetic ride shock at the rear right corner
• Loss of adaptive response in GM magnetorheological suspension systems
• Factory shock wear on Cadillac DTS and Buick Lucerne models with Magneride
• Need for a direct-fit replacement that communicates with the ECU

Installation Notes and Tips

Fits 2006-2011 Buick Lucerne, rear right, with Magneride RPO Code F55. Fits 2006-2011 Cadillac DTS, rear right, with Magneride RPO Code F55. Confirm the vehicle is equipped with the GM magnetorheological damper system before ordering MR-3447, and verify the rear right position matches the original shock location.

Quality Assurance

Arnott’s NEW line focuses on replacement parts built for factory-style fit and electronic integration. MR-3447 is made to connect to the vehicle ECU without modification and to replicate the adaptive behavior of the OE magnetic ride system.
