The Down Sus line is developed specifically for daily-driven vehicles that want a lower stance and reduced body roll while retaining a comfortable, livable ride.\u003c\/p\u003e\n\u003ch4\u003eFAQ\u003c\/h4\u003e\n\u003cstrong\u003eWhat is the RSRT539D?\u003c\/strong\u003e\n\u003cp\u003eThe RSRT539D is a RS-R Down Sus lowering spring set built for the 2022 to 2026 Lexus NX350 AWD and NX350h FWD, dropping the vehicle roughly 1.0 to 1.8 inches depending on drivetrain and axle while retaining the factory shock absorbers.\u003c\/p\u003e\n\u003cstrong\u003eDoes this fit both the NX350 and NX350h?\u003c\/strong\u003e\n\u003cp\u003eYes, RSRT539D is matched for the NX350 AWD and the NX350h FWD drivetrain configurations. Confirm your specific drivetrain before ordering, since drop amounts differ slightly between the two.\u003c\/p\u003e\n\u003cstrong\u003eWill this spring set work with my factory shocks?\u003c\/strong\u003e\n\u003cp\u003eYes. RS-R Down Sus springs are engineered to pair with factory shock absorbers, so no additional dampers are required.\u003c\/p\u003e\n\u003cstrong\u003eHow much drop should I expect?\u003c\/strong\u003e\n\u003cp\u003eNX350 AWD sees roughly 1.6 to 1.8 inches front and 1.0 to 1.2 inches rear. NX350h FWD sees roughly 1.0 to 1.2 inches front and 1.2 to 1.4 inches rear.\u003c\/p\u003e\n\u003cstrong\u003eDo I need an alignment after installing these springs?\u003c\/strong\u003e\n\u003cp\u003eYes. Any ride height change affects camber and toe, so a full four-wheel alignment is strongly recommended after installation.\u003c\/p\u003e\n\u003cstrong\u003eCan I install this spring set myself?\u003c\/strong\u003e\n\u003cp\u003eInstallation requires a spring compressor and standard suspension tools. Experienced DIY mechanics can typically complete the job, though professional installation is recommended if you are unfamiliar with compressed coil springs.\u003c\/p\u003e\n\u003cstrong\u003eDoes this kit include new shocks or struts?\u003c\/strong\u003e\n\u003cp\u003eNo. RSRT539D replaces only the coil springs and is designed to work with your existing factory strut and shock assemblies.\u003c\/p\u003e\n\u003cstrong\u003eWill lowering my NX affect the factory warranty?\u003c\/strong\u003e\n\u003cp\u003eSuspension modifications can affect warranty coverage on suspension-related components.
