Product Details

Bilstein B12 (Pro-Kit) is a suspension kit line built around matched components rather than mixed aftermarket parts. The dampers and springs are selected for each vehicle application to deliver a lowered stance while maintaining predictable road manners. For Mercedes-Benz CLK350, CLK550, C280, C350, CLK500, C240, C320, and CLK320 models, part number 46-181817 provides a front and rear suspension solution for vehicles without self-leveling suspension.

This part cross-references Eibach E90-25-001-02-22 for the same application.
