Keep the rear of your Lexus RX300 riding and handling the way it was engineered with the KYB Excel-G Suspension Strut 334270, a nitrogen gas-charged, twin-tube gas strut that installs as a direct-fit replacement for the 1999-2003 Lexus RX300. Cataloged for the rear left position, the Excel-G is built on the same KYB OE assembly lines with the same OE-quality components and is calibrated to restore the vehicle's original designed performance — earning KYB's OEA (Original Equipment for the Aftermarket) classification.
- Twin-tube, nitrogen gas-charged design: includes the quality components found in KYB's global OEM products.
- Triple-lip fluid seal: helps reduce the chance of oil and gas leaking out.
- Vehicle-specific, hand-assembled damping valves: manage tire contact, steering response and body movement.
- Thick strut bodies and brackets: minimize flex to help maintain correct alignment; made in USA.
The Excel-G helps restore the designed control and handling of your RX and supports the electronic safety systems that depend on the suspension working as intended. KYB recommends installing new strut mounts (part number SM5175) and protecting the unit with a KYB Strut Boot (part number SB101).
