Unity Automotive Suspension Shock Absorber P/N:12-512800
Unity Automotive 13-512800 rear shock absorber for the 2006-2013 Mercedes-Benz R350 and other vehicles damps rear suspension movement. It replaces a worn or leaking rear shock absorber.
A worn suspension shock absorber can show up as a bouncy ride after bumps, oil on the shock body or uneven tire wear. Before you replace this shock absorber, rule out a problem in the air supply or the electronic suspension control, since the same ride signs can have other causes and a shop can test those systems.
It fits the 2006-2013 Mercedes-Benz R350, the 2007-2009 Mercedes-Benz R320 and the 2006-2008 Mercedes-Benz R500. This listing is one rear shock absorber and these cars take two at the rear, so order two and fit them together.
