Product Details

The KYB Excel-G line is built on KYB OE assembly lines using OE-quality components and calibration focused on restoring the vehicle’s original performance rather than changing it. For Toyota 4Runner and Lexus GX460 front suspension service, this strut is designed to support consistent control during lane changes, braking, and everyday road use. Part number 340085 also cross-references Monroe Shocks & Struts 801371 for the same application.

Common Issues This Strut Can Address

• Excessive front-end bounce or float
• Reduced steering response during turns and lane changes
• Nose dive under braking
