KYB 339208 Suspension Strut - Rear Right

KYB Excel-G Rear Right Strut for Lexus RX

KYB Excel-G suspension strut 339208 is an OE-style replacement built to restore original ride control, stability, braking response, and handling. It is a direct-fit rear right strut for select Lexus RX applications, including Lexus RX350 and Lexus RX400h models listed below.

The Excel-G line is KYB’s original-equipment replacement series, built on the same OE assembly lines and calibrated to return the vehicle to its designed damping characteristics rather than change them.

• Vehicle-specific damping valves for controlled tire contact, steering response, and body motion
• Triple-lip fluid seal to reduce oil and gas leakage
• Strong strut body and bracket construction to help minimize flex and maintain alignment
• Rear right application for Lexus RX fitments listed below
• Cross-reference: Monroe Shocks & Struts 72763 for the same application

What This Strut Helps Address

• Excessive bounce or poor damping at the rear right corner
• Reduced lane-change stability and body control
• Longer stopping distances caused by worn suspension control
• Uneven tire contact and steering response issues from suspension wear
• Noise or fluid leakage associated with aging strut seals

Installation Notes and Tips

Verify rear right placement before ordering and confirm the vehicle is not equipped with air suspension where excluded. For the 2008 Lexus RX400h application, follow the manufacturer instruction to replace the suspension strut and coil spring assembly as specified. Inspect related suspension components, mounts, and alignment settings during installation. KYB also recommends a strut boot such as SB104 to help protect the unit from dirt, debris, and road salt.
