KYB Suspension Shock Absorber P/N:3440137
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.
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.
