ICON Vehicle Specific (V.S.) 2.5 Series shocks are designed and built to provide outstanding performance off-road and a smooth ride on the street. These shocks are configured specifically for each application in both length and damping tune. They are 100% rebuildable and revalveable. For piggyback and specific remote reservoir applications, ICON's unique use of a 6061 billet aluminum manifold creates an internal Bump Zone that increases damping by 20% to prevent harsh bottom outs. The ICON CDC Valve is an externally adjustable valve offering 10 levels of compression damping force ranges.
