Restore the designed ride control, stability, and handling of your Lexus and Toyota with the KYB Excel-G Suspension Strut 334400, a nitrogen gas-charged, twin-tube unit for the FRONT LEFT position. It installs as a direct-fit replacement for the 2004-2006 Lexus RX330, 2007-2009 Lexus RX350, 2006-2008 Lexus RX400H, and 2001-2007 Toyota Highlander. Built on the same KYB OE assembly lines with the same OE-quality components, the Excel-G is calibrated to restore original designed performance rather than change it — earning KYB's OEA (Original Equipment for the Aftermarket) classification.
- Triple-lip fluid seal: reduces the chance of oil and gas leaking out.
- Vehicle-specific damping valves: hand assembled in-house to correctly manage tire contact, steering response, and body movement.
- Strong strut body and brackets: among the thickest in the industry, minimizing flex to help maintain correct alignment in all conditions.
- Safety-system support: helps keep Electronic Safety Systems performing as designed.
KYB recommends installing new strut mounts (part number SM5423) to reduce the chance of noise and vibration, and protecting the strut with a KYB Strut Boot (part number SB102). It's the #1 recommended Original Equipment replacement choice for Asian SUVs and Crossovers.
