Product Details

KYB is an original equipment supplier, and the Strut-Plus line is built for direct suspension replacement where ride height, steering pivot function, and stability are critical. The SR4783 is engineered for the front left position on the Toyota Highlander and uses a matched spring and strut assembly to restore suspension geometry and road feel. This part number, SR4783, is a practical OE-style replacement for Highlander owners addressing worn front suspension components.

The Strut-Plus line focuses on complete strut assembly replacement rather than rebuilding individual components. For the 2014-2019 Toyota Highlander, that means a front left assembly built around KYB’s OE-restoring strut design and a coil spring developed to match the vehicle’s load characteristics. This helps maintain proper ride height and suspension performance after replacement.

Common Issues This Part Addresses

• Front-end sag or reduced ride height
• Worn strut performance causing loose or unstable handling
• Noisy or tired front suspension response
• Uneven steering feel from a worn front left strut assembly
• Loss of factory ride quality on a Toyota Highlander

Installation Notes and Tips

Fits 2014-2019 Toyota Highlander, front left. Confirm the vehicle’s trim and suspension configuration before ordering, and verify the existing strut matches the listed position. Because this is a suspension strut and coil spring assembly, professional installation and a wheel alignment are recommended after replacement. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
