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 RSRT525D?\u003c\/strong\u003e\n\u003cp\u003eThe RSRT525D is a RS-R Down Sus lowering spring set designed for the 2022 to 2026 Lexus NX350h F Sport AWD, dropping the vehicle roughly 1.0 to 1.4 inches in front and 1.2 to 1.6 inches in the rear using factory shocks.\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 the factory shock absorbers, so no additional dampers are required for installation.\u003c\/p\u003e\n\u003cstrong\u003eHow much does the NX350h drop with RSRT525D installed?\u003c\/strong\u003e\n\u003cp\u003eExpect approximately 1.0 to 1.4 inches of drop up front and 1.2 to 1.6 inches in the rear, giving a noticeably tighter fender gap while preserving ride comfort.\u003c\/p\u003e\n\u003cstrong\u003eDoes this fit the non-F Sport NX350h?\u003c\/strong\u003e\n\u003cp\u003eRSRT525D is matched specifically to the F Sport AWD suspension tuning. Non F Sport trims may ride differently with this spring rate, so confirm your trim before ordering.\u003c\/p\u003e\n\u003cstrong\u003eWill lowering springs affect my alignment?\u003c\/strong\u003e\n\u003cp\u003eAny change in ride height affects camber and toe. A professional alignment is strongly recommended after installation to protect tire wear and handling.\u003c\/p\u003e\n\u003cstrong\u003eIs this a full replacement of the strut and shock assembly?\u003c\/strong\u003e\n\u003cp\u003eNo. RSRT525D replaces only the coil springs and is designed to work with your existing factory strut and shock assemblies.\u003c\/p\u003e\n\u003cstrong\u003eCan I install these springs myself?\u003c\/strong\u003e\n\u003cp\u003eInstallation requires a spring compressor and standard suspension tools. Most experienced DIY mechanics can complete the job, though a professional installation is recommended if you are not comfortable working with compressed coil springs.\u003c\/p\u003e\n\u003cstrong\u003eDoes lowering the NX350h with this kit void the factory warranty?\u003c\/strong\u003e\n\u003cp\u003eSuspension modifications can affect warranty coverage on suspension-related components.
