KYB SR4386 Suspension Strut and Coil Spring Assembly - Front Right

KYB Strut-Plus Front Right Assembly

The KYB Strut-Plus SR4386 is a suspension strut and coil spring assembly for the front right position on select Nissan and INFINITI models. Built to restore ride height, handling response, and steering control, it combines an OE-restoring KYB strut with a high carbon steel coil spring matched to vehicle attributes and corner weights.

Compatible with 2013-2016 Nissan Pathfinder, front right, 2014-2015 INFINITI QX60, front right, and 2013 INFINITI JX35, front right. The KYB Strut-Plus line is focused on complete strut assemblies that return the suspension to original ride geometry and support consistent vehicle stability.

Detailed Description

KYB Strut-Plus SR4386 is built for drivers replacing a worn front right strut assembly on the Nissan Pathfinder, INFINITI QX60, or INFINITI JX35. As a suspension strut and coil spring assembly, it addresses the structural and dynamic role of the front suspension by supporting vehicle weight, helping maintain ride height, and serving as a steering pivot point. KYB’s OE supplier background is reflected in the way this assembly is engineered to return the vehicle’s original handling balance and suspension geometry. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Solve

• Front-end sag or uneven ride height
• Excessive bounce or reduced damping control
• Loose, unstable, or imprecise steering feel
• Noisy or worn strut assembly operation
• Loss of original suspension response after wear

Installation Notes and Tips

Install SR4386 only on the confirmed front right application listed above. Verify compressed length, extended length, and stroke length against the removed assembly before installation. Because this is a complete strut and spring assembly, it is suited for service where restoring ride height and suspension control are priorities. After installation, a professional wheel alignment is recommended to confirm steering and suspension geometry.

Quality Assurance

KYB manufactures OE-focused suspension components, and the Strut-Plus line is engineered around original ride characteristics and vehicle-specific spring rates. The assembly uses a high carbon steel coil spring and an OE-restoring strut design to support consistent fitment and suspension performance.
