Rear Shock Absorber for Audi A4 and A5

Unity 257050 is a twin-tube gas-charged shock absorber designed as a direct OE replacement for the rear suspension. It fits 2009-2016 Audi A4 Sedan and Quattro models, plus 2008-2016 Audi A5 and A5 Quattro variants. The part excludes vehicles equipped with Sport or Electronic Suspension systems.

Thermals noise and power draw

As a passive suspension component, this shock absorber generates no heat, draws no electrical power and produces no audible noise during normal operation. Its twin-tube gas-charged design manages hydraulic fluid flow to control damping forces across varying road conditions.

Build fit and clearance

Installation requires standard suspension tools and the existing mounting hardware on compatible Audi chassis. The unit frees the vehicle from worn OE damping characteristics and restores original ride quality. Orders of $75 or more ship free directly from the manufacturer.

Questions about this item

How is the Unity 257050 rear shock absorber installed, and which step do people get wrong?

It installs as a direct replacement for the original equipment shock on 2008‑2016 Audi A4 and A5 models, excluding Sport and Electronic Suspension; the common error is fitting it to a vehicle that has electronic damping, which this unit does not support.

What maintenance or replacement will the Unity 257050 rear shock absorber need later?

As a twin‑tube gas‑charged shock absorber, it requires no scheduled servicing; replacement is only necessary if the unit begins to leak fluid, loses damping control, or shows physical damage after extended use.

What limit appears first on the Unity 257050 rear shock absorber under sustained use?

The first limit is thermal fade — prolonged heavy driving can heat the hydraulic fluid enough to reduce damping consistency until the shock cools down.
