KYB Strut-Plus Front Right Assembly

The KYB Strut-Plus SR4119 is a front right suspension strut and coil spring assembly built for direct replacement on select Toyota applications. It combines an OE-restoring KYB strut with a vehicle-specific coil spring to help return ride height, steering response, and stability to factory specifications.

Product Details

KYB Strut-Plus is a suspension strut and coil spring assembly line focused on restoring original ride height and handling balance. For the SR4119, KYB pairs an OE-restoring strut with a high-carbon steel coil spring selected around vehicle attributes and corner weights, helping the suspension return to OE ride-height targets. This part number, SR4119, is built for the front right position and is designed for the 2003-2009 Toyota 4Runner and 2007-2009 Toyota FJ Cruiser.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Excessive front-end bounce or poor damping control
• Sagging ride height from a worn coil spring
• Loose or imprecise steering feel from a tired strut assembly
• Uneven handling response during braking, cornering, or lane changes
• Suspension wear that can affect ESC, ABS, and related systems

Installation Notes

Fits 2003-2009 Toyota 4Runner, front right. Fits 2007-2009 Toyota FJ Cruiser, front right. Verify that the vehicle is not equipped with X-REAS or adjustable suspension before ordering. Follow the manufacturer’s service procedure for strut and coil spring replacement, and confirm side-specific orientation before installation. SR4119 is pre-assembled, which helps reduce the need to transfer spring components during service.

Quality Assurance

KYB is an original equipment supplier, and the Strut-Plus line is engineered around OE fit, ride height, and handling characteristics. The SR4119 is assembled in the USA and built with application-specific components to support consistent suspension performance on the listed Toyota models.
