Description

ICON Vehicle Specific (V.S.) 2.5 Aluminum Series shocks are designed and built to give your vehicle 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. Like all ICON'S Shock Absorbers, V.S. 2.5 Aluminum Series shocks are 100% rebuildable and 100% revalveable. For piggyback and specific remote reservoir applications, ICON'S unique use of a 6061 billet aluminum manifold a few inches below the top cap of the shock creates an internal Bump Zone that when used creates an additional 20% of damping force. This additional force helps prevent harsh bottom outs and controls the suspension when compressing at high velocity. ICON's exclusive Compression Damping Dual Speed (CDXS) valves are included for precisely dialing in your suspension performance. CDXS controls fluid flow under compression, with independent adjustability of high speed and low speed compression force. 10 discreet detented settings for both low and high-speed adjustment knobs allow separate adjustments for handling response and overall aggressiveness.

ICON Vehicle Dynamics specializes in performance suspension components, shocks, and accessories for todays most popular trucks & SUVs. Since 2008, ICON has been developing products that redefine the limits of what a “stock vehicle is capable of. ICON is part of a family of manufacturing companies that includes state of the art machining, laser cutting, and metal forming processes.
