# ICON 11-26 GM 2500/3500 HD 0-2in Rear VS 3.0 RR CDXS 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 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.

-   One-piece linear compression/digressive rebound piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road
-   ICON CDXS equipped for independent adjustability of high speed and low speed compression force for handling response and aggressiveness
-   ICON’s internal “Bump Zone” increases damping by 20% to provide more control as the shock approaches full compression
-   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
-   Offset upper eyelet allows fitment into factory shock mounts
-   Nitrogen charged monotube design with remote reservoir
-   6061 aircraft grade aluminum CNC machined components
-   100% Rebuildable
-   100% Revalveable
