The Rough Country Ford F-Series Nitro 9000 Series Shock Absorbers incorporate self adjusting "Velocity Sensitive Valving".

This allows for a super smooth highway ride and outstanding control in rugged off-road situations from the same shock, without turning any knobs or shock removal for re-adjustment.

Each shock sold features a performance proven 10-stage variable valving that allows for self adjusting pressure regulation to keep your shock performing at full potential. Fully charged with 200 psi of nitrogen to allow for a smooth ride while being under full compression. Incorporates poly-urethane bushings to help to keep your shock going for a lifetime.
