Restore the designed ride control and handling of your truck with the KYB Excel-G rear shock absorber (P/N 344414). This KYB shock absorber drops in as a direct-fit replacement for the listed 2004-2008 Ford F-150 and 2006-2008 Lincoln Mark LT applications. Excel-G is a nitrogen gas-charged, twin-tube gas shock absorber built on the same KYB OE assembly lines with the same OE-quality components, calibrated to restore the vehicle's original designed performance rather than change it — earning it the OEA (Original Equipment for the Aftermarket) classification.
Worn shocks may show up as excess body movement, a bouncy ride, or reduced stability during lane changes and braking. Rear shocks work as a set — replacing both sides together is recommended for balanced ride control. See the Buyer's Guide tab for the full engine-level fitment.

What are the signs my shocks may need replacing?
Common signs include a bouncy ride, excess body movement, reduced stability during lane changes, or oil seepage. Diagnose the cause before replacing, as other suspension parts can contribute.
