Restore a level, controlled ride on your Mercedes-Benz with the Arnott Industries Air Suspension Spring A-2791 (also written A2791), a rear-left air spring assembly that replaces the worn factory unit. It's a direct-fit replacement for the listed applications, including the 2012-2014 CLS350, 2015-2018 CLS400, 2012-2018 CLS500, 2012-2018 CLS550, 2012-2014 CLS63 AMG, 2014-2018 CLS63 AMG S, 2012-2016 E200, 2011-2012 and 2014-2016 E250, 2010-2016 E300, 2010-2016 E350, 2013-2016 E400, 2010-2016 E500, 2010-2016 E550, 2010-2016 E63 AMG, and 2014-2016 E63 AMG S — see the Buyer's Guide tab for the full list and engine specifics.
The air spring supports the vehicle's corner, absorbs road inputs, and maintains proper ride height when the compressor and air lines are working correctly. If a leaking or collapsed original rear-left air spring is the cause of a sagging corner or a harsh ride, this assembly replaces it.
- Tested: Lab-verified and road-proven, built to Arnott's development standards.
- ISO quality: Manufactured under strict ISO quality standards.
- Durable: Engineered for strength to withstand demanding road conditions.
- Pair recommendation: For best results, replace in pairs.
