Arnott MR-3854 Suspension Shock Absorber - Rear Left

Arnott Magnetic Air Shock for Audi TT RS and TTS

The Arnott MR-3854 is a rear left magnetic shock for select 2016-2023 Audi TT and TTS models, including TT RS Quattro applications. It uses magnetorheological fluid and internal electromagnetic control to match the adaptive ride behavior of the original electronic suspension.

Built as part of Arnott’s Magnetic Air Shock line, this rear shock connects to the vehicle ECU with no modifications and is engineered for direct OE-style replacement on Audi TT/TT RS and TTS (8S) platforms.

Key Features

• Standard-grade suspension shock absorber for the rear left position
• Magnetic ride design with magnetorheological fluid for electronically controlled damping
• Monotube damper construction for consistent suspension response
• Direct ECU connection with no vehicle modifications required
• OE-style replacement for Audi TT/TT RS and TTS magnetic suspension systems
• Arnott part number MR-3854 for easy identification and ordering

Detailed Description

The MR-3854 is an Arnott Magnetic Air Shock designed for the rear left side of Audi TT RS Quattro and Audi TTS Quattro models equipped with electronic suspension. The shock uses a magnetic damping system that changes fluid viscosity and stiffness through electromagnetic control, helping preserve the adaptive ride characteristics expected from the factory setup. For buyers searching for a rear left magnetic shock for 2016-2023 Audi TTS Quattro or 2018-2023 Audi TT RS Quattro, MR-3854 provides a direct-fit replacement solution. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What This Part Helps Address

• Rear suspension damping loss or inconsistent ride control
• Electronic suspension warning concerns tied to the rear left shock
• Excessive bouncing, harshness, or reduced road isolation
• Wear in the original magnetic ride shock on Audi TT and TTS models
• Need for an OE-style rear left replacement on magnetic suspension vehicles

Installation Notes and Tips

Fits 2018-2023 Audi TT RS Quattro, rear left, w/Electronic Suspension; Magnetic Air Shock. Fits 2016-2023 Audi TTS Quattro, rear left, Magnetic Air Shock. Confirm the rear left position and electronic suspension configuration before installation. Because this shock connects to the ECU without modifications, it is intended for vehicles already equipped with the matching magnetic suspension system.

Quality Assurance

Arnott’s Magnetic Air Shock line is built for OE-style fit and electronic suspension integration on supported Audi applications. MR-3854 is engineered to restore factory-type magnetic damping behavior on the specified TT RS and TTS models.
