The Rough Country N2.0 series nitrogen charged shock absorbers incorporate self adjusting "Velocity Sensitive Valving". This technology varies the resistance valving incorporated in the shock according to piston rod speed. 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.
These rear N2.0 shocks are good for stock height to 3.5" lift and have longer travel than stock shocks. These come with heavy duty stem cushions/bushings, cushion washers and polyurethane shock boots. They are powdercoated silver. These shocks are very reliable and are an excellent value.
