2005-2022 Ford F-250/F-350 Super Duty 4WD 4.5 Inch Lift Front 2.5 Vs Piggyback Reservoir Shocks Pair Icon Vehicle Dynamics

ICON’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. With a truly vehicle-specific design, these shocks are configured specifically for each application in both length and damping tune. Featuring one-piece impact extruded aluminum cylinders, these 2.5 Aluminum Series shocks offer lighter weight, improved corrosion resistance, and a more uniform finish than traditional plated steel cylinders. Like all ICON shock absorbers, these 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 InchBump Zone Inch that when used creates an additional 20 Percent of damping force. This additional force helps prevent harsh bottom-out conditions and controls the suspension effectively when compressing at high velocity. If you are looking for a more user-defined tune, consider looking into the Compression Damping Control Valve (CDCV) shocks. Features and Benefits: Premium grade 5WT shock oil for consistent suspension damping along a wide temperature range One piece digressive piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road 100 Percent Revalveable Nitrogen charged monotube design with piggyback reservoir 100 Percent Rebuildable One-piece impact extruded aluminum cylinders offer excellent corrosion resistance and consistent finish Remote reservoir design improves heat dissipation to reduce shock fade during prolonged use Double-sealed Schrader caps reduce risk of damage 6061 aircraft grade aluminum CNC machined components ICON’s internal InchBump Zone Inch increases damping by 20 Percent to provide more control as the shock approaches full compression 7/8 Inch diameter induction hardened, chrome plated shock shaft PTFE lined spherical bearings and application specific mounting hardware All ICON 2.5 Series Piggyback and Remote Reservoir shocks can be upgraded to ICON’s Compression Damping Control Valve (CDCV) Details Adjustable: No Boot Included: No Bore Diameter: 2.25 Cylinder Color: Silver Cylinder Material: Aluminum Damping Type: Oil External Reservoir: Yes Gas Charged: Yes Grade Type: Performance Lower Mount Type: Eyelet Mounting Hardware Included: Yes Oem Wheels & Tires Fitment: Not Compatible With All Available OE Wheel/Tire Combinations.
