Product Details

The KYB Excel-G line is engineered to restore the vehicle’s original suspension behavior rather than change it. For the Lexus RX400h and Toyota Highlander, this KYB 334385 rear left strut uses OE-quality components and factory-calibrated damping to help return the vehicle to its designed ride and handling balance. It is a practical choice for drivers addressing worn suspension on a Toyota Highlander rear left strut or Lexus RX400h rear left suspension repair.

This part cross-references Monroe Shocks & Struts 72214 for the same application.

What It Helps Address

• Excessive bouncing after bumps
• Reduced braking stability and nose dive
• Loose or delayed steering response
• Uneven tire contact and body roll
• Noise or vibration from a worn rear strut assembly

Installation Notes and Tips

Fits 2004-2007 Toyota Highlander, rear left. Fits 2006-2007 Lexus RX400h, rear left. For 2004-2007 Toyota Highlander and 2006-2007 Lexus RX400h applications, replace the suspension strut and coil spring assembly according to the manufacturer’s instructions.
