KYB is a world-leading supplier of shocks and struts to new-vehicle manufacturers, and the Excel-G is made on the very same OE assembly lines using the same OE-quality components. It's calibrated to restore the vehicle's original designed performance rather than change it, and helps keep electronic safety systems performing as intended. If a worn rear shock is behind excess body movement or poor ride control, this KYB gas shock absorber is designed to bring damping back to spec.
