ST Suspensions X Coilovers - Chrysler 300 / Dodge Charger RWD 2011-2023

The ST X coilover kit is a height-adjustable suspension system for the RWD Chrysler 300 and Dodge Charger, engineered by KW in Germany for everyday drivers who want sharper handling without giving up ride comfort. It uses galvanized zinc-coated steel struts with a hardened chrome piston rod, a friction-optimized polyamide composite spring perch with a stainless-steel insert for corrosion-free height adjustment, and a multi-layer pressure-resistant sealing package with a mono-block guide system. Dampers and spring rates are application-specific and dyno-tested by hand in Fichtenberg, Germany.
