Product Description

The Bilstein 46-180766 is a B12 Pro-Kit complete suspension lowering kit engineered for RWD variants of the Mercedes-Benz W204 C-Class (C250, C300, C350; 2008-2014) and W212 E-Class (E350, E400, E550; 2010-2017). The kit combines Bilstein's B8 Performance Plus monotube dampers with Eibach Pro-Kit progressive lowering springs, matched and tuned together by Bilstein engineers for the specific suspension geometry and weight distribution of these platforms. The result is approximately 30mm of front and rear drop that meaningfully reduces body roll, sharpens turn-in response, and delivers a more planted, sport-oriented driving character without sacrificing daily usability.

Installation is direct bolt-on with no modification required, and OE suspension geometry is fully preserved at the lowered ride height - eliminating concerns about rubbing or binding. This kit is compatible with the full range of naturally aspirated and turbocharged engine variants across the C250, C300, C350, E350, E400, and E550 in RWD configuration, but is not suitable for 4MATIC AWD models or vehicles equipped with Active Body Control, AIRMATIC air suspension, or Agility Control adaptive damping. Backed by Bilstein's Limited Lifetime Warranty.
