Product Line Details

KYB Excel-G is the brand’s Original Equipment for the Aftermarket line, focused on restoring factory ride characteristics rather than changing them. For drivers and technicians looking for a Lexus RX350 strut replacement or a Lexus RX450h front right suspension strut, KYB Excel-G 3340263 is built to match the vehicle’s original control and response.

Detailed Description

Part number 3340263 is a KYB Excel-G suspension strut for the front right position on select Lexus RX models. It is engineered for 2016-2022 Lexus RX350, 2018-2022 Lexus RX350L, 2020-2022 Lexus RX450h without air suspension, and 2018-2022 Lexus RX450hL. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application. If you need a KYB 3340263 replacement strut for Lexus RX350 or RX450h front right fitment, this unit is designed to restore the vehicle’s original suspension behavior.

What It Helps Address

• Excessive bouncing or reduced damping control
• Loose or unstable front-end feel during braking
• Reduced lane-change responsiveness
• Uneven handling over bumps and road transitions
• Loss of factory ride control on the front right corner

Installation Notes and Tips
