Unity 257150 Rear Shock Absorber

The Unity 257150 is a direct-replacement rear shock absorber designed for specific Audi models including A4, A5, A6, A7, S4 and S5 across model years 2008 to 2018. It targets owners and mechanics restoring ride control on vehicles equipped with sport suspension or standard setups excluding Magnetic Ride Control and adaptive damping systems.

Twin-tube gas-charged construction

The twin-tube gas-charged design provides consistent damping force during extended driving rather than fading after repeated compression cycles. Unity's manufacturing focus on suspension components aims to deliver reliable performance over the vehicle's remaining service life without the degradation typical of worn original equipment units.

Verify fitment before ordering

Confirm your exact model year, trim and suspension type against the listed applications because this unit excludes Magnetic Ride Control and adaptive damping configurations. Check that the rear mounting points match the original equipment design for a trouble-free installation on your specific Audi.

Questions about this item

Does the twin-tube gas-charged design run hotter than oil-only shocks during long drives?

The gas-charged twin-tube construction helps dissipate heat more evenly than oil-only units, so temperature stays stable on extended journeys.

What tools are needed to install this rear shock absorber on an Audi A4?

Standard metric sockets, a torque wrench and a spring compressor are required to remove the old unit and fit this direct-replacement shock.

Will this shock fit a 2015 Audi S4 that still has its original adaptive suspension?

No, the part is listed for the 2015-2016 S4 only without adaptive control, so it will not match the magnetic-ride-equipped model.
