On the AS-2540, the original epoxy-style upper seal is replaced with O-ring sealing technology to reduce the cracking and leakage issues commonly associated with aging air struts. The result is a front air suspension strut engineered for Mercedes-Benz S-Class vehicles that need restored ride height control, damping response, and air spring function. This part cross-references Mercedes-Benz 2213204913 and 2213209313 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat This Part Helps Fix\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eFront-end sagging from a leaking air spring bladder\u003c\/li\u003e\n\u003cli\u003eAir suspension warning lights caused by pressure loss\u003c\/li\u003e\n\u003cli\u003eUneven ride height at the front of the vehicle\u003c\/li\u003e\n\u003cli\u003eExcessive bounce or reduced damping control\u003c\/li\u003e\n\u003cli\u003eCracked upper seal areas that lead to air leaks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eFits 2011-2013 Mercedes-Benz S350, front.
