Product Details

The KYB Excel-G line is built on KYB OE assembly lines using OE-quality components and calibration focused on restoring factory performance rather than changing it. Part number 235906 is designed for the rear right position and is a practical choice when replacing a worn strut on a Lexus RX330 or Lexus RX350. This part cross-references Monroe Shocks & Struts 72213 for the same application.

For buyers searching for a rear right strut for 2004-2006 Lexus RX330 or 2007 Lexus RX350, KYB 235906 provides the OE-style damping and structural support expected from the Excel-G line. It is also a fitment-focused option for drivers looking to restore suspension response on the Lexus RX platform without altering the vehicle’s original ride characteristics.

What This Strut Helps Address

• Excessive bouncing or poor rebound control
• Reduced braking stability and longer stopping feel from worn suspension
• Loose steering response during lane changes and cornering
• Uneven tire contact caused by weakened damping
• Noise or vibration associated with worn rear suspension components
