Unity Automotive Air Suspension Strut P/N:18-573000
Unity Automotive 18-550000 rear air suspension strut for the 2012-2016 Tesla S replaces the factory air ride at the rear. It carries the rear load on an air sleeve and helps control wheel movement.
A rear end that sags, sits unevenly or rides rough can point to a worn or leaking air suspension strut. These signs alone do not prove the strut is at fault, since a leaking air line is another common cause. Rear struts are normally replaced together, and this listing covers a single one.
This direct-fit strut needs no modifications on the 2012-2016 Tesla S.
