Arnott MR-4358 Magnetic Strut for Cadillac XTS

Arnott MR-4358 is a front magnetic strut for the 2013-2019 Cadillac XTS equipped with GM MagneRide. This direct OE replacement uses a monotube damper with magnetorheological fluid and an electromagnetic coil to vary damping response through the vehicle ECU.

Key Features

• Direct OE replacement magnetic strut for the front suspension
• Fits the front left or front right side on the Cadillac XTS
• Monotube damper design for controlled suspension response
• Magnetorheological fluid changes viscosity when energized by the coil
• Connects to the vehicle ECU with no modifications
• New, standard-grade suspension strut from Arnott Magnetic Strut
• Part number MR-4358 for easy identification and ordering

Detailed Description

Arnott MR-4358 is built for 2013-2019 Cadillac XTS models with GM MagneRide front suspension. As part of Arnott’s Magnetic Strut line, this unit is engineered as a direct OE-style replacement for the original electronically controlled strut, helping restore factory suspension behavior on the Cadillac XTS front end. The design uses magnetorheological fluid and an internal electromagnetic coil to adjust damping stiffness in real time through the ECU. This part number, MR-4358, is specified for front left or right installation and is intended for vehicles that require a magnetic suspension strut replacement without wiring changes or custom modifications.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Front suspension noise or loss of damping control
• Electronic strut failure on GM MagneRide-equipped Cadillac XTS models
• Uneven ride quality at the front of the vehicle
• Warning lights or suspension performance issues related to the active strut system
• Replacement needs for worn OE magnetic struts

Installation Notes and Tips

Compatible With 2013-2019 Cadillac XTS, front left or front right. Verify MagneRide-equipped front suspension before ordering. Mounting hardware is not included. Because this is an electronically controlled suspension component, follow factory service procedures and confirm ECU connections are secure during installation of MR-4358.

Quality Assurance

Arnott manufactures this new magnetic strut as a direct OE replacement for the Cadillac XTS front suspension system. The part is built to match the vehicle’s electronic damping architecture and restore proper operation of the MagneRide setup.
