Product Details

KYB Excel-G is built on the same KYB OE assembly lines used for original equipment production and calibrated to restore designed performance rather than change it. For this application, part number 334264 is a rear left suspension strut for 1999-2003 Lexus RX300 and 2001-2003 Toyota Highlander models. This part cross-references Monroe Shocks & Struts (e.g., 71499) for the same application. The Excel-G line is focused on restoring the vehicle’s original ride control, which is important for import SUV handling, stopping stability, and electronic safety system performance.

What This Strut Helps Address

• Excessive bouncing or poor rebound control
• Loose rear-end handling during turns or lane changes
• Uneven tire contact caused by worn suspension damping
• Noise or vibration from a fatigued rear strut assembly
• Reduced braking stability from worn suspension components

Installation Notes and Tips

Fits 1999-2003 Lexus RX300, rear left. Fits 2001-2003 Toyota Highlander, rear left. Manufacturer instructions call for replacing the suspension strut and coil spring assembly as directed for this application. KYB recommends new strut mounts, part number SM5175, to reduce noise and vibration, and a KYB strut boot, part number SB101, to help protect the strut from dirt, debris, and salt.

Quality Assurance

KYB is a major OE supplier of shocks and struts, and Excel-G is classified as an Original Equipment for the Aftermarket replacement line. Part number 334264 is engineered to match original suspension behavior for the listed Lexus RX300 and Toyota Highlander applications.
