Restore the designed control and handling of your Lexus RX with the KYB Excel-G Suspension Strut 339244, a nitrogen gas-charged, twin-tube unit that drops in as a direct-fit replacement for the 2008-2009 Lexus RX350 in the rear right position. KYB is a world-leading supplier of shocks and struts to new-vehicle manufacturers, and the Excel-G is built on the same OE assembly lines using the same OE-quality components, calibrated to restore original, designed performance rather than change it — earning it the OEA (Original Equipment for the Aftermarket) classification.
- Nitrogen gas-charged twin-tube design: includes every quality component KYB's global OEM products use, and is the preferred choice of professional technicians.
- Triple-lip fluid seal: reduces the chance of oil and gas leaking out.
- Vehicle-specific, hand-assembled damping valves: correctly manage tire contact, steering response and body movement.
- Strong, thick strut bodies and brackets: minimize flex to help maintain correct alignment in all conditions.
Excel-G helps keep Electronic Safety Systems performing as designed. KYB recommends installing new strut mounts (part number SM5491) and protecting your new struts with a KYB Strut Boot (part number SB104). Made in USA.
