Restore the designed ride control, stability, and handling of your Lexus RX400h with the KYB Excel-G Gas Strut 339210, a nitrogen gas-charged, twin-tube damper built for the rear right position. It drops in as a direct-fit replacement for the 2006-2007 Lexus RX400h and 2006-2007 Toyota Highlander, and it's assembled on the same KYB OE lines using the same OE-quality components — earning its OEA (Original Equipment for the Aftermarket) classification, calibrated to restore original performance rather than change it.
- Twin-tube, nitrogen gas-charged design: includes every quality component found in KYB's global OEM products.
- Hand-assembled, vehicle-specific damping valves: manage tire contact, steering response, and body movement.
- Strong, thick strut body and brackets: help minimize flex to maintain correct alignment in varied conditions.
- Triple-lip fluid seal: designed to reduce the chance of oil and gas leaking out.
Worn struts can show up as excessive body movement, reduced stability, or poor handling; if the original strut is the cause, this replaces it. To reduce the chance of noise and vibration, KYB recommends installing new strut mounts (part number SM5491), and you can protect the new strut from dirt, debris, and salt with a KYB Strut Boot (part number SB104).
