The H&R Sport Spring kit for 2003–2008 Infiniti FX45 (2WD/AWD) reduces ride height to tighten fender gaps and lower the center of gravity for improved handling. The progressive-rate springs cut body roll while maintaining ride comfort. Constructed from shot-peened 54SiCr6 spring steel and produced in Germany, these lightweight springs are H&R's go-to choice for a sportier stance and potential fuel-economy benefits.
