Product Details

KYB Strut-Plus SR4678 is built for drivers replacing a worn front left strut assembly on a Kia Sorento. As an OE supplier, KYB applies original equipment fit and performance targets to the strut and spring package, helping restore ride height within OE specifications while supporting stable handling and steering control. This part number, SR4678, is a direct-fit suspension strut and coil spring assembly for 2011, 2012, and 2013 Sorento applications at the front left corner.

The Strut-Plus line focuses on complete corner service, pairing a KYB strut with a matched coil spring rather than replacing only one component. That approach helps maintain suspension geometry and consistent ride characteristics after repair. This KYB SR4678 assembly is also relevant for shoppers searching for a 2011-2013 Kia Sorento front left strut assembly or OE-style replacement strut and spring unit.

What It Can Help Address

• Front-end sag or ride height loss
• Excessive bounce or reduced damping control
• Loose or inconsistent steering feel
• Uneven suspension response at the front left corner
• Wear-related replacement of the original strut assembly

Installation Notes

Fits 2011-2013 Kia Sorento, front left. Verify spring orientation, mounting points, and suspension condition before installation. Because this is a complete strut and coil spring assembly, it is suited for replacing the full corner unit rather than transferring the original spring. Professional installation and a wheel alignment are recommended after suspension service.

Quality Assurance

KYB is an original equipment supplier, and the Strut-Plus line is engineered to restore handling, control, and ride height using OE-focused components. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
