Product Details

KYB Excel-G is KYB’s Original Equipment for the Aftermarket line, built to restore the vehicle’s original suspension performance rather than alter it. This rear suspension strut uses OE-quality components and calibration intended to match the Lexus LS430’s factory ride characteristics. It is a practical choice for replacing worn rear struts on 2001-2006 Lexus LS430 models, especially when the goal is to recover stable braking, lane-change response, and consistent body control. This part cross-references Monroe Shocks & Struts (e.g., 72342) for the same application.

What This Strut Helps Address

• Excessive rear bounce or float over uneven pavement
• Reduced braking stability from worn suspension damping
• Loose or delayed handling response during lane changes
• Uneven tire contact caused by weakened strut control
• Suspension noise or fluid leakage from an aging rear strut
