Arnott MR-3839 Front Magnetic Strut

Arnott MR-3839 is a front magnetic strut for GM full-size SUVs and trucks equipped with MagneRide. It is a new OES-style replacement that restores electronically controlled damping for the left or right front position on supported applications.

Magnetic Ride Features

• Magnetic strut with monotube internal construction
• Magnetorheological fluid changes damping response when energized by the vehicle system
• Adjustable damping for adaptive ride control
• Universal front fitment for left or right side on listed applications
• Spring seat included; mounting hardware included
• New unit with no air adjustment, no coil springs, and no boot included

Fitment and Application Details

Compatible with 2015-2020 Cadillac Escalade and Escalade ESV front suspension, 2015-2020 Chevrolet Tahoe front suspension with Magneride RPO Code Z95, 2015-2020 GMC Yukon and Yukon XL front suspension with Magneride RPO Code Z95, and 2015-2018 Chevrolet Silverado 1500 and GMC Sierra/Sierra 1500 front suspension with Magneride RPO Code Z95. Arnott MR-3839 connects to the vehicle ECU with no modifications and is built to match the adaptive behavior of the OE magnetic strut.

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

Common Problems It Can Address

• Front suspension noise from a worn magnetic strut
• Excessive bounce or reduced damping control
• Loss of adaptive ride response in MagneRide-equipped vehicles
• Uneven front ride quality on Cadillac Escalade, Chevrolet Tahoe, or GMC Yukon models
• Warning lights or drivability issues related to a failing front electronic strut

Installation Notes

Verify MagneRide RPO Code Z95 before ordering. MR-3839 is a universal front strut for the left or right side on the listed vehicles, and it connects to the ECU without modification. Always confirm the vehicle’s front suspension configuration and inspect related mounting points, sensors, and hardware before installation.

Quality Assurance

Arnott’s Magnetic Strut line is engineered for electronically controlled GM suspension systems and uses a monotube damper filled with magnetorheological fluid for rapid damping changes. Part number MR-3839 is a new replacement designed for direct electronic integration on supported Cadillac, Chevrolet, and GMC applications.
