Keep the adaptive magnetic ride of your Audi tuned and controlled with the Arnott Industries Suspension Shock Absorber (MR-3854), an OES-design magnetic damper for the rear-left corner. It drops in as a direct-fit replacement for the 2018-2023 Audi TT RS Quattro and 2016-2023 Audi TTS Quattro (8S), matching the highly adaptive ride behavior of the factory unit.

  • Magnetorheological monotube damper: The monotube is filled with magnetorheological fluid — a synthetic hydrocarbon oil carrying easily magnetized iron particles.
  • Two electromagnetic coils: Coils inside the damper instantly change the bonds between the magnetized iron particles, altering the viscosity and stiffness of the suspension when energized.
  • Connects to the ECU: Arnott's universal magnetic-ride shock connects to the vehicle's ECU with no modifications.
  • OES design and components: Precision-tuned to deliver the same adaptive ride control as the original equipment.

This is the rear-left shock. For best results, Arnott recommends replacing the shocks in pairs. If a worn or failed magnetic shock at this corner is the cause of poor ride control, this replaces it.

Frequently Asked Questions

Which vehicles does the Arnott MR-3854 fit?

It is a direct-fit replacement for the 2018-2023 Audi TT RS Quattro and 2016-2023 Audi TTS Quattro (8S). See the Buyer's Guide tab to confirm your vehicle.

What position is this shock for?

This is the rear-left magnetic shock absorber. Order the matching corner for your vehicle.

How does this magnetic shock work?

The monotube is filled with magnetorheological fluid holding iron particles; two internal electromagnetic coils change how those particles bond, altering suspension viscosity and stiffness when energized.

Does it connect to the factory system?

Yes. Arnott's universal magnetic-ride shock connects to the vehicle's ECU with no modifications.

Should I replace shocks in pairs?

Arnott recommends replacing the shocks in pairs for best results. This listing covers the rear-left unit only.
