1999-2025 Ford F-250/F-350/F-450 Super Duty 0-3 Inch Lift Rear V.S. 2.5 Aluminum Series Shocks Piggyback Reservoir W/ CDCV Pair Icon Vehicle Dynamics

ICON Vehicle Specific (V.S.) 2.5 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 Percent rebuildable and 100 Percent 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 Percent of damping force. This additional force helps prevent harsh bottom outs and controls the suspension when compressing at high velocity. The ICON CDC Valve is an externally adjustable valve that restricts oil flow into the reservoir which creates 10 levels of compression damping force ranges. Features and Benefits: ICON’s CDC Valve technology allows for 10 levels of high-resolution compression adjustability with the turn of a knob ICON’s internal InchBump Zone Inch increases damping by 20 Percent to provide more control as the shock approaches full compression Remote reservoir design improves heat dissipation to reduce shock fade during prolonged use Premium grade 5WT shock oil for consistent suspension damping along a wide temperature range Nitrogen charged monotube design with piggyback reservoir One piece digressive piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road 7/8 Inch diameter induction hardened, chrome plated shock shaft PTFE lined spherical bearings and application specific mounting hardware 6061 aircraft grade aluminum CNC machined components One-piece impact extruded aluminum cylinders offer excellent corrosion resistance and consistent finish 100 Percent Rebuildable 100 Percent Revalveable Details Active Or Passive Suspension: Passive Adjustable: Yes Adjustable Compression: Yes Adjustable Damping: Yes Adjustable Rebound: No Boot Included: No Bore Diameter: 2.25 Cylinder Color: Gray Cylinder Diameter: 2.5 Cylinder Material: Aluminum Damping Adjustment Type: Manual Damping Type: Oil External Reservoir: Yes Gas Charged: Yes Grade Type: Performance Includes Bump Stop: No Lower Mount Type: Eyelet Mounting Hardware Included: Yes Reservoir Type: Piggyback Service Parts: 257342 – 7/8 Shaft 16.85 Oal, 12.00 Travel, 252001 – 2.5 Fixed Spanner Wrench, 254100G – 1 Gallon Icon Performance Shock Oil, 252002 – Universal Spanner Wrench (2.0/2.5/3.0), 252011 – 2.5 Piggyback/Remote Resi/Bypass Rebuild Kit, 252003 – Seal Install Tool 2.5/3.0, 191015 – 10 Inch Finned Resi Upgrade Kit Shaft Diameter: 0.875 Shaft Material: Chrome Shock Absorber Body End Measuring Point: Center Of Eyelet Shock Absorber Rod End Measuring Point: Center Of Eylet Tube Outside Diameter: 2.5 Upper Mount Type: Eyelet Valving Type: Digressive
