Smooth out the ride and restore control on your Super Duty with the KYB shock absorber, part number 344419 — a nitrogen gas-charged, twin-tube Excel-G rear shock that drops in as a direct-fit replacement for the 1999-2004 Ford F-250 Super Duty and 1999-2016 Ford F-350 Super Duty. Built on the same KYB OE assembly lines using OE-quality components, the Excel-G is calibrated to restore your truck's original designed damping — not to change it — which earned it KYB's OEA (Original Equipment for the Aftermarket) classification and helps keep the Electronic Safety Systems performing as the manufacturer intended.

  • Gas-charged twin-tube design: nitrogen gas-charged Excel-G construction that includes the quality components found in KYB's global OEM products.
  • Triple lip fluid seal: reduces the chance of oil and gas leaking out.
  • Strong strut bodies and brackets: thick bodies and brackets minimize flex to help maintain correct alignment in all conditions.
  • Vehicle-specific damping valves: hand-assembled in-house to manage tire contact, steering response and body movement.

Signs this rear shock may need replacing include excessive bounce over bumps, front-end dive under braking, body sway, and reduced stability during lane changes. If worn rear shocks are the cause of these symptoms, this Excel-G unit helps restore the designed control and handling.
