The H&R Sport Spring kit for 2005–2010 Chrysler 300 C LX (without self-leveling, non-AWD) applications lowers ride height to tighten fender clearance and lower the center of gravity for crisper handling. Its progressive spring rate reduces body roll while keeping comfortable ride quality and can modestly improve aerodynamic drag. Built from 54SiCr6 spring steel with shot peening and block-setting, these lightweight springs are made in Germany and are a go-to suspension upgrade.
