Product Details

KYB Strut-Plus SR4130 is part of KYB’s Strut-Plus line, a suspension solution focused on restoring original ride characteristics with OE-style geometry and damping control. As an original equipment supplier, KYB builds this assembly to help return proper ride height and handling balance while maintaining the steering pivot function of the strut. The SR4130 is engineered for front right use on 2003-2009 Toyota 4Runner, front right, except X-Reas and adjustable suspensions, and 2007-2009 Toyota FJ Cruiser, front right. This part cross-references Monroe Shocks & Struts (e.g., 171352L) for the same application.

What It Helps Address

• Front-end sag or uneven ride height
• Excessive bounce, body motion, or reduced damping control
• Loose or imprecise steering feel from worn strut components
• Noise or instability caused by aging suspension hardware
• Restoration needs after replacing a worn front right strut assembly

Installation Notes and Tips

Install the SR4130 on the front right position only. Verify vehicle configuration before ordering, since 2003-2009 Toyota 4Runner applications exclude X-Reas and adjustable suspensions. Follow the manufacturer’s service procedure for strut replacement and alignment checks after installation. Because this is a pre-assembled strut and coil spring assembly, it is intended to simplify professional suspension service while preserving OE-style fitment.

Quality Assurance

KYB is an original equipment supplier, and the Strut-Plus line is engineered around vehicle-specific ride height, damping, and handling requirements. The SR4130 is assembled in the USA and built with application-specific components to support consistent suspension performance on the listed Toyota 4Runner and Toyota FJ Cruiser applications.
