# ICON 20-26 GM 2500/3500 HD 0-3.5in Front VS 3.0 RR CDCV Pair

ICON Vehicle Specific (V.S.) 3.0 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. 3.0 Series shocks boast 50% more piston surface area compared to 2.5 Series shocks. This translates into increased stability and vehicle control at the extremes of off-road use, with benefits also making themselves apparent in on-road driving conditions. Increased internal oil volume and more external surface area compared to 2.5 Series shocks offer improved heat dissipation and resistance to shock fade under hard use. Like all ICON shock absorbers, V.S. 3.0 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 Control Valves are included for precisely dialing in your suspension performance. CDCV controls fluid flow under compression, allowing you to achieve the perfect tune whether driving on the street, slow-crawling through the rocks or mobbing across the desert at full throttle.

-   One-piece linear compression/digressive rebound piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road
-   ICON’s internal “Bump Zone” increases damping by 20% to provide more control as the shock approaches full compression
-   ICON's CDC Valve technology allows for 10 levels of high-resolution compression adjustability with the turn of a knob
-   Extended travel length requires ICON Delta Joint Pro front upper control arms and provides maximum wheel travel
-   Press in, bonded rubber bushing/bar pin assembly damps road vibration and provides OE factory type fitment
-   Premium grade 5WT shock oil for consistent suspension damping along a wide temperature range
-   Remote reservoir design improves heat dissipation to reduce shock fade during prolonged use
-   Cerakoted steel cylinders offer excellent corrosion resistance and consistent finish
-   Vehicle specific design and tuning for superior shock damping and control
-   3.0” Body diameter for increased oil volume and larger piston area
-   7/8” diameter induction hardened, chrome plated shock shaft
-   Nitrogen charged monotube design with remote reservoir
-   6061 aircraft grade aluminum CNC machined components
-   Compatible with 0-3.5" of front lift over stock
-   100% Rebuildable
-   100% Revalveable
