Product Details

The KYB Excel-G line is KYB’s OE replacement series, built on the same assembly lines and with the same quality components used for original equipment applications. This strut is calibrated to return the suspension to factory-style performance rather than change ride characteristics. Part number 339102 is a direct-fit front right suspension strut for 2007-2010 Toyota Sienna models, including 8-passenger seating applications listed in the fitment data.

This part cross-references Monroe Shocks & Struts 72365 for the same application.

What This Strut Helps Address

• Excessive front-end bounce or float
• Reduced steering response during turns and lane changes
• Uneven tire contact caused by worn damping control
• Brake dive and unstable stopping feel
• Noise or vibration from a worn front right strut assembly

Installation Notes

Fits 2007-2010 Toyota Sienna, front right. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends installing new strut mounts, part number SM5423, to reduce noise and vibration. Verify upper mount type 14X1.50 and confirm all suspension components are in serviceable condition before installation.

Quality Assurance

KYB is a major OE supplier, and Excel-G is engineered to match original suspension performance targets for ride control, stability, and handling. Electronic safety systems depend on suspension, brakes, and tires operating as designed, and this strut helps maintain that factory-intended behavior.
