Unity 11720 Front Strut Assembly

The Unity 11720 is a complete front strut assembly built to original equipment specifications for Mercedes R-Class models. It fits 2007-2009 R320, 2006-2013 R350 and 2006-2008 R500 vehicles and arrives fully preassembled with top mount, bearing plate, coil spring and gas-charged cartridge.

Direct-Fit Installation Limits

The unit bolts on using existing mounting points and requires no spring compressors or specialty tools during installation. Because it restores factory ride height, suspension geometry remains within the original design envelope and no alignment changes are introduced beyond normal wear adjustments.

Single-Side Capacity And Service Life

Each assembly is sold individually and rated at 19 lbs with a packaged dimension of 25 x 9 x 9 inch. It comfortably handles daily driving loads and restores damping performance on the fitted corner, though replacing both front struts together is advised for balanced handling and even tyre wear.

Questions about this item

Does the 11720 fit a 2009 R320 and a 2013 R350 the same way?

The 11720 is listed for 2007‑2009 R320, 2006‑2013 R350 and 2006‑2008 R500, so it covers both model years with the same direct‑fit design.

What does the pre‑assembled 11720 change on the car once fitted?

It restores factory ride height and ride feel using a gas‑charged cartridge, new coil spring, top mount, bearing plate, bump stop, insulators and dust boot — all installed as one unit.

How does the bolt‑on design of the 11720 affect the tools needed for installation?

Because the strut arrives fully assembled, no spring compressor or specialty tools are required; it bolts to the existing mounting points with standard hardware.
