Arnott states the internal settings were tested to replicate OE performance, giving the assembly the ride characteristics expected from the original suspension layout. The steel twin-tube body, hydraulic damper, and passive operation make this a practical replacement for restoring consistent rear suspension response. Part number SK-4209 is also referenced by JL1Z18125C and JL1Z18125J for the same application.\u003c\/p\u003e\u003cp\u003eArnott's product line focuses on replacement suspension components that mirror original equipment behavior while using new components and application-specific engineering. For buyers looking for a Lincoln Navigator or Ford Expedition rear left strut assembly, SK-4209 provides a complete suspension unit with spring and related support components already integrated.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRear suspension sag or reduced ride height\u003c\/li\u003e\n\u003cli\u003eExcessive bounce or inconsistent damping response\u003c\/li\u003e\n\u003cli\u003eNoisy or worn strut and spring components\u003c\/li\u003e\n\u003cli\u003eLoss of OE-like ride control in CCD-equipped vehicles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify fitment by year, make, model, position, and CCD equipment before installation.
