Help restore the designed ride control, stability, and handling of your Lexus SUV with the KYB Excel-G Suspension Strut (MPN 235906), a nitrogen gas-charged, twin-tube unit for the rear right position. It's a direct-fit replacement for the 2004-2006 Lexus RX330 and 2007 Lexus RX350 — see the Buyer's Guide tab for engine-level detail. Built on KYB's OE assembly lines with OE-quality components, the Excel-G is calibrated to restore original, designed performance rather than change it, earning its OEA (Original Equipment for the Aftermarket) classification.
- Nitrogen gas-charged, twin-tube design: includes the same quality components found in KYB's global OEM products; the #1 recommended OE replacement choice for Asian SUVs and crossovers.
- 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, helping keep electronic safety systems performing as designed.
- Strong, thick strut body and brackets: minimize flex to help maintain correct alignment in all conditions.
To reduce the chance of noise and vibration, KYB recommends installing new strut mounts, part number SM5491. Sold individually — replace struts in pairs across an axle for balanced ride and handling.
