Product Details

KYB Strut-Plus SR4645 combines a KYB strut with a coil spring developed around vehicle attributes and corner weights. As an OE supplier, KYB builds this assembly to restore the handling and control characteristics expected from the original suspension design. For Toyota Corolla rear suspension service, SR4645 provides a direct-fit solution for the rear left position on 2014-2019 models, including 2019 Corolla applications except Japan-built vehicles.

The Strut-Plus line is designed as a complete strut assembly approach for suspension replacement, helping maintain proper ride height and steering pivot function while supporting vehicle stability. This part number, SR4645, is a practical choice when replacing worn rear suspension components on a Toyota Corolla.

What It Helps Address

• Sagging rear ride height
• Worn strut performance and reduced damping control
• Excessive body motion over bumps and uneven pavement
• Rear suspension noise related to aging strut assembly components
• Handling changes caused by tired coil spring and strut wear

Installation Notes

Verify rear left fitment before installation. This assembly is listed for 2014-2019 Toyota Corolla rear left applications, with 2019 coverage excluding Japan-built vehicles. Confirm vehicle build details, suspension configuration, and part match before service. Professional installation and a post-repair alignment are recommended after suspension replacement.
