Restore the ride control, stability, and handling of your Honda or Acura with the KYB Excel-G Suspension Strut 340066. This nitrogen gas-charged, twin-tube front strut drops in as a direct-fit replacement for the 2004-2008 Acura TL, 2004-2008 Acura TSX, and 2003-2007 Honda Accord. Built on KYB's OE assembly lines with the same 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.
- Twin-tube, gas-charged design: includes every quality component found in KYB's global OEM products, the preferred choice of professional technicians.
- Vehicle-specific damping valves: hand-assembled in-house to 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.
- Triple-lip fluid seal: reduces the chance of oil and gas leaking out.
The Excel-G also helps keep electronic safety systems performing as the vehicle manufacturer intended. To reduce the chance of noise and vibration, KYB recommends installing new strut mounts (part number SM5058), and protecting the strut with a KYB Strut Boot (part number SB108).
