KYB Excel-G Front Left Strut for Toyota Sienna

The KYB Excel-G 339101 is a front left suspension strut for 2007-2010 Toyota Sienna models with 7 passenger seating. Built to restore original ride control and handling, it is calibrated to return the vehicle’s designed steering response, stability, and braking feel.

As part of the KYB Excel-G line, this strut is made on KYB OE assembly lines using OE-quality components and an OE-style damping setup. It is a direct replacement choice for Toyota Sienna owners looking to bring suspension performance back to factory intent without changing the vehicle’s original character.

Detailed Description

KYB Excel-G 339101 is engineered as an OE-style replacement strut for the Toyota Sienna front left position. It is designed to restore the vehicle’s original ride control, lane-change response, and body motion management, which is important for daily driving, braking stability, and suspension balance. The Excel-G line is built to match original performance characteristics rather than alter them, making it a practical choice for maintaining factory-like handling on the Toyota Sienna.

This part cross-references Monroe Shocks & Struts 72364 and Gabriel G56798 for the same application. For reduced noise and vibration, KYB recommends replacing the strut mount with SM5423 during service.

What It Helps Address

• Excessive front-end bounce or float
• Reduced steering response during lane changes
• Uneven tire contact caused by worn damping
• Body movement that affects braking stability
• Oil or gas leakage from an aging strut assembly

Installation Notes and Tips

Compatible with 2007-2010 Toyota Sienna, front left, including 7 passenger seating applications. Verify the upper mount thread specification of 14X1.50 and confirm the compressed, extended, and stroke dimensions before installation. KYB recommends installing a new strut mount, part number SM5423, to help reduce noise and vibration during service.

Quality Assurance

KYB is a major OE supplier, and the Excel-G line is produced on the same assembly lines used for original equipment applications. The design uses OE-quality components and application-specific damping calibration to support factory-style suspension performance on the Toyota Sienna.
