Bring back the settled, controlled ride your truck left the factory with using the KYB Excel-G Rear Suspension Strut 341607. It installs as a direct-fit replacement for the 2003-2006 Ford Expedition (see the Buyer's Guide tab for engine-level applications), and it's built on the same KYB OE assembly lines using OE-quality components — earning the Excel-G its OEA (Original Equipment for the Aftermarket) classification, calibrated to restore the vehicle's original designed performance rather than change it.
- Nitrogen gas-charged twin-tube design: includes every quality component found in KYB's global OEM products, the choice preferred by professional technicians.
- Triple-lip fluid seal: helps reduce the chance of oil and gas leaking out.
- Vehicle-specific, hand-assembled damping valves: assembled in-house to manage tire contact, steering response, and body movement.
- Strong, thick strut body and brackets: minimize flex to help maintain correct alignment in a range of conditions.
As a KYB recommended OEM replacement strut for domestic SUVs and crossovers, the Excel-G helps restore the designed control and handling of your Ford Expedition and helps keep electronic safety systems performing as intended. For balanced ride control, replacing struts as a pair is a good practice.
