Detailed Description

The Arnott MR-4360 is engineered for drivers searching for a rear left magnetic shock for Cadillac XTS MagneRide suspension systems. As part of Arnott’s Magnetic Shock product line, this unit replaces the original rear left strut on 2013-2019 Cadillac XTS models while maintaining electronic control through the factory ECU. The design uses a monotube damper filled with magnetorheological fluid, allowing the suspension stiffness to change when the electromagnetic coil is energized.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. Search terms such as Cadillac XTS rear left magnetic strut, 2013-2019 Cadillac XTS MagneRide shock, and Arnott MR-4360 rear suspension replacement align with this application.

What It Helps Address

• Rear suspension noise or harshness from a worn magnetic strut
• Loss of damping control in MagneRide-equipped Cadillac XTS models
• Uneven rear ride quality on the left side
• Warning lights or suspension performance issues related to the factory electronic shock
• Need for a direct OE-style rear left replacement on the 2013-2019 Cadillac XTS

Installation Notes and Tips

Install on the rear left position only. Verify MagneRide-equipped fitment before ordering, and transfer no assumptions from non-magnetic suspension setups. Because the unit connects to the ECU without modification, factory-style electrical integration is retained. Follow OEM service procedures for suspension removal, torque specifications, and post-installation inspection.

Quality Assurance

Arnott manufactures this MR-4360 as a direct OE replacement for the Cadillac XTS rear left magnetic shock application. The part is built as a standard-grade suspension shock absorber and is pre-assembled for safety and service readiness.
