Arnott Industries MR-3839 front suspension strut for the 2015-2018 Chevrolet Silverado 1500 and other vehicles damps front-wheel movement as part of an active magnetic suspension. It is a magnetically controlled strut with OES design and components.
- Monotube damper filled with magnetorheological fluid, a synthetic hydrocarbon oil with easily magnetized iron particles
- Two electromagnetic coils inside the damper change the bonds between the iron particles, altering viscosity and suspension stiffness when turned on
- Universal design: one strut fits the left or right front side
- Connects to the vehicle's ECU with no modifications
- Active suspension with adjustable damping
Quick facts
- Part: Arnott Industries MR-3839 suspension strut
- Fits: 2015-2018 Chevrolet Silverado 1500 and other vehicles
- Position: Front
- Condition: New
A worn or leaking strut can show up as fluid on the strut body, a bouncy or harsh ride, or a clunk over bumps. Before replacing it, look the strut body over for fluid with the engine off; if the strut is the cause, this one replaces it, and a shop can test the electronic side.
Fits
This strut is a direct replacement for the GM MagneRide shock on the 2015-2018 GMC Sierra 1500 and the 2015-2020 Chevrolet Tahoe, and these vehicles take two. This listing is one strut; the other front side takes its own, and the pair is normally replaced at the same time. If your vehicle is not named here, find its year and model in the "Vehicles it fits" section.
