Excel-G Product Line Details

KYB Excel-G is engineered on the same OE assembly lines used for original equipment production and uses OE-quality components calibrated to restore original suspension performance rather than change it. For Lexus RX400h and Toyota Highlander rear suspension service, part number 339211 is built to match the vehicle’s designed ride control characteristics.

Detailed Description

The KYB Excel-G 339211 is a rear left suspension strut for 2006-2007 Lexus RX400h and 2006-2007 Toyota Highlander models. It is designed to return the suspension to factory-like response by controlling rebound and compression with vehicle-specific damping calibration. This helps maintain proper tire contact, steering response, and body control in everyday driving. This part cross-references Toyota 4854049365 for the same application.

What It Helps Address

• Excessive bounce or float from worn rear suspension damping
• Reduced stability during lane changes and cornering
• Uneven tire contact caused by weak strut control
• Noisy or inconsistent rear suspension response from aging components
• Loss of original ride control on Lexus RX400h and Toyota Highlander rear suspension

Installation Notes and Tips

Fits 2006 Lexus RX400h, rear left. Fits 2007 Lexus RX400h, rear left. Fits 2006-2007 Toyota Highlander, rear left. Replace the suspension strut and coil spring assembly according to the manufacturer’s instructions. KYB recommends installing new strut mounts, part number SM5492, to reduce noise and vibration, and a KYB strut boot, part number SB104, to help protect the strut from dirt, debris, and salt.
