Product Details

KYB Strut-Plus SR4703 is engineered as a direct suspension replacement for the front left corner on the INFINITI QX60 and Nissan Pathfinder. KYB’s OE supplier background is reflected in the assembly’s focus on restoring original ride height and suspension geometry, while the spring is selected to match vehicle attributes and corner weights. For shoppers searching for a front left strut assembly for 2016-2020 INFINITI QX60 or a 2017-2020 Nissan Pathfinder front left suspension strut and coil spring assembly, SR4703 provides a complete service solution in one unit. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues This Part Addresses

• Front-end sag or reduced ride height
• Loose or inconsistent steering feel
• Excessive body motion over bumps and dips
• Uneven suspension response at the front left corner
• Worn strut performance affecting vehicle stability

Installation Notes and Tips

Install on the front left position only. Verify vehicle year, make, model, and suspension configuration before ordering, and inspect related components such as mounts, control arms, and alignment settings during service. Because this is a complete strut and spring assembly, it is suited for replacing a worn front left unit without transferring the spring from the old strut.

Quality Assurance

KYB manufactures suspension components as an original equipment supplier, and the Strut-Plus line is built to restore handling, control, and ride height using OE-focused engineering and matched spring rates.
