Front Magnetic Coil Strut for GM SUVs

The Arnott MR-3840 is a new front magnetic coil strut assembly for 2015-2020 Cadillac Escalade, Chevrolet Tahoe, and GMC Yukon models equipped with Z95 MagneRide. It restores factory ride height and preserves the adaptive response expected from a MagneRide suspension system.

Built as a direct replacement, the MR-3840 arrives pre-assembled for front-position installation and is engineered for GM K2 platform short wheelbase 2WD SUVs. Arnott also offers a separate ride-height option in this product line for applications that need additional lift.

Key Features

  • Fits 2015-2020 Cadillac Escalade, front
  • Fits 2015-2020 Chevrolet Tahoe, front
  • Fits 2015-2020 GMC Yukon, front
  • Magnetic internal damper with magnetorheological fluid for real-time damping response
  • Pre-assembled strut with coil spring, upper strut mount, bump stop, spring seat, and isolators
  • Powder-coated spring and black finish for corrosion resistance
  • New, direct replacement suspension strut and coil spring assembly
  • Designed and assembled in the USA

Product Details

The Arnott Magnetic Coil Strut Assembly MR-3840 uses an OES monotube damper filled with magnetorheological fluid, where iron particles react to the electromagnetic coil and change fluid viscosity as conditions change. That allows the suspension to adjust stiffness in real time while maintaining the factory character of the MagneRide system. This part number, MR-3840, is intended to restore original ride height on the front of GM short wheelbase 2WD SUVs with Z95 MagneRide, including Cadillac Escalade, Chevrolet Tahoe, and GMC Yukon applications.

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

Common Problems This Part Can Address

  • Front-end sag or reduced ride height
  • Loss of proper MagneRide damping response
  • Worn or noisy strut mount and spring components
  • Uneven ride quality at the front suspension
  • Need for a direct OE-style replacement on GM K2 platform SUVs

Installation Notes

MR-3840 is a front-position assembly and is supplied pre-assembled for plug-and-play installation. Verify Z95 MagneRide equipment, short wheelbase 2WD configuration, and front fitment before installation. Arnott recommends replacing struts in pairs to maintain balanced suspension performance. A detailed installation manual is included.

Quality Assurance

Arnott manufactures this magnetic coil strut assembly as a new replacement part with OE-style construction and application-specific engineering for GM MagneRide systems. The assembly is built to restore factory ride height and maintain adaptive suspension function on the listed Cadillac Escalade, Chevrolet Tahoe, and GMC Yukon models.
