Restore the original ride control, stability, and handling of your Lexus or Toyota with the KYB Excel-G Suspension Shock Absorber 349203, a nitrogen gas-charged, twin-tube damper built for the rear right position. It drops in as a direct-fit replacement for the 2010-2022 Lexus RX350, 2018-2022 Lexus RX350L, 2010-2022 Lexus RX450H, 2018-2022 Lexus RX450HL, 2014-2022 Toyota Highlander, and 2021-2026 Toyota Sienna — see the Buyer's Guide tab for engine-level fitment. Built on KYB's OE assembly lines using OE-quality components, the Excel-G is calibrated to restore designed performance rather than change it, earning its OEA (Original Equipment for the Aftermarket) classification.
- Twin-tube gas design: nitrogen gas-charged construction that includes the same quality components found in KYB's global OEM products.
- Triple-lip fluid seal: reduces the chance of oil and gas leaking out.
- Vehicle-specific damping: hand-assembled, in-house damping valves manage tire contact, steering response, and body movement.
- Strong strut bodies and brackets: among the thickest in the industry to minimize flex and help maintain correct alignment.
KYB helps keep electronic safety systems performing as designed, since they depend on the suspension, brakes, and tires operating as the manufacturer intended.
