Detailed Product Overview

The Bilstein B14 (PSS) series is built for drivers who want a lower, more controlled suspension setup without moving away from a direct-fit format. This kit uses monotube dampers paired with application-specific springs to maintain predictable response while allowing the ride height to be set for the vehicle’s intended use. Part number 47-231108 is listed for 2014-2019 Mercedes-Benz CLA250 and 2014-2019 Mercedes-Benz CLA45 AMG, with fitment notes for vehicles without electronic suspension.

This part cross-references Monroe Shocks & Struts (e.g., 10225065) for the same application. The Bilstein B14 (PSS) line is the product family to look for when you need adjustable lowering, direct-fit suspension geometry, and a corrosion-resistant threaded body in one package.
