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, 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. If you are looking for a more user defined tune, consider looking into the Compression Damping Control Valve (CDCV).. ICON 2.5 Series shocks are designed to give you outstanding performance off-road and a smooth ride on the street. With a vehicle-specific design, these shocks are configured specifically for each application in both length and damping tune.. OEM Wheels & Tires Fitment: Not compatible with all available OE wheel/tire combinations. Aftermarket wheels with lower offset/less backspace recommended.. One piece, hard anodaized, digressive piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road. TECH NOTE: Compatible with 0-2.75” of front lift over stock of 2020-2022 F-250/F-350 4WD equipped with Tremor package. ICON's internal "Bump Zone" increases damping by 20% to provide more control as the shock approaches full compression.
