Description

Arnott Industries MR-3854 rear left shock absorber for the 2018-2023 Audi TT RS Quattro and other vehicles uses magnetically controlled damping to manage the ride. Also called a suspension shock absorber, it is an OES magnetic shock that gives the same highly adaptive ride as the OE.

Monotube damper filled with magnetorheological fluid
Magnetorheological fluid is a synthetic hydrocarbon oil that holds easily magnetized iron particles
Two electromagnetic coils in the damper change the bonds between the iron particles, altering viscosity and stiffness when turned on
Connects to the vehicle's ECU with no modifications

A bouncy or unsettled ride, fluid on the shock body or uneven tire wear can mean this shock is worn, though a weak rear spring or a worn suspension bushing can also be behind them, so find the cause before replacing it. Replace the rear shocks as a pair for best results; this listing is one shock for the left side, and the right side is its own part.

Fits

It fits the 2018-2023 Audi TT RS Quattro and the 2016-2023 Audi TTS Quattro, and each takes one for the rear left position.
