ST Suspensions X Coilovers - Dodge Challenger 2011-2023

The ST X coilover kit is a ride-height adjustable suspension system engineered for daily-driven 2011-2023 Dodge Challenger applications, balancing sporty handling with everyday road comfort. Dampers and spring rates are tuned in Germany for each specific application and built by hand at KW in Fichtenberg, with every damper shock-dyno tested. Galvanized zinc-coated steel struts and a friction-optimized polyamide composite spring perch with a stainless-steel insert resist corrosion for long-lasting height adjustability.
