Product Details

KYB Strut-Plus SR4395 is built around KYB’s OE-restoring strut design and a high-carbon steel coil spring selected to match vehicle attributes and corner weights. That approach helps restore ride height within OE specifications while supporting the handling and control characteristics expected from the original suspension. For Lexus ES300h and Lexus ES350 front left service, this assembly provides a direct replacement format that reduces the need to transfer separate spring and strut components during installation.

The Strut-Plus line focuses on complete, application-specific suspension assemblies for drivers who want a factory-style repair path. KYB’s role as an original equipment supplier informs the damping and spring tuning used in this assembly, making the SR4395 a practical choice for restoring front suspension performance on the Lexus ES300h and Lexus ES350.

What It Helps Address

• Excessive front-end bounce or oscillation
• Uneven or incorrect ride height at the front left corner
• Reduced steering precision or vague road feel
• Noisy or worn suspension strut and spring components
• Loss of stability during braking, cornering, or lane changes

Installation Notes

Fits 2013-2018 Lexus ES300h, front left. Fits 2013-2018 Lexus ES350, front left. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions.
