Rear Shock Absorber for Mercedes R-Class

This Unity rear shock absorber is a direct replacement for original equipment on Mercedes-Benz R320 models from 2007 to 2009, R350 models from 2006 to 2013, and R500 models from 2006 to 2008. It is designed for owners restoring ride quality on these specific vehicles without active damping systems.

Twin-Tube Gas Charged Design

The unit uses a twin-tube gas-charged construction built to withstand daily driving demands over extended periods. Unity’s 50 years of aftermarket manufacturing experience backs a design focused on long-lasting reliability and consistent damping performance throughout the component’s service life.

Direct OE Replacement Fitment

Installation follows a trouble-free, direct-fit process that matches the original mounting points on the listed Mercedes models. The critical constraint is that this shock absorber excludes vehicles equipped with Active Dampening Suspension (ADS), so buyers with that factory option cannot use this part.

Questions about this item

Does the 12-512800 rear shock absorber produce noticeable noise or heat during extended daily driving?

The twin-tube gas-charged design runs quietly and dissipates heat normally; no extra noise or thermal load is introduced during all-day operation.

What existing suspension components must be present for the 12-512800 to install correctly on a 2007-2009 Mercedes-Benz R320?

Standard rear mounting points and non-ADS suspension hardware are required; the unit is a direct replacement for original equipment shocks on those models.

Will the 12-512800 work alongside the original front struts on a 2006-2013 Mercedes-Benz R350 without causing handling imbalance?

Yes, it matches OE rear damping characteristics so the factory front struts remain compatible and handling stays balanced.
