Icon Vehicle Dynamics 71704EP Suspension Shock Absorber Set for Chevy/GMC

20-26 GM 2500/3500 HD 0-3.5" FRONT VS 3.0 RR CDEV 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. Compatible with 0-3.5" of front lift over stock Vehicle specific design and tuning for superior shock damping and control 3.0” Body diameter for increased oil volume and larger piston area Extended travel length requires ICON Delta Joint Pro front upper control arms and provides maximum wheel travel ICON’s internal “Bump Zone” increases damping by 20% to provide more control as the shock approaches full compression
