Arnott Industries MR-3856 front suspension strut for the 2009-2015 Audi TTS Quattro and other vehicles adjusts damping with magnetorheological fluid and two electromagnetic coils. It is an OES magnetic strut that restores factory ride and handling and gives the same highly adaptive ride as the OE.
- Monotube damper filled with magnetorheological fluid, a synthetic hydrocarbon oil that contains easily magnetized iron particles
- Two electromagnetic coils inside the damper change the fluid's viscosity and stiffness when turned on
- Universal design that works on either the left or the right side
- Connects to the vehicle's ECU with no modifications
- OES design and components
