ICON: 4.5″ Lift Front VS 2.5 Aluminum Series Shocks RR Pair – 2023-25 Ford F-250/F-350 Super Duty 4WD

Description

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% rebuildable and 100% revalveable. Remoyte reservoirs greatly increase shock oil volume and heat dissipation surface area to resist overheating and cavitation under hard use, which can lead to damper fade. 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-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.

Key features:
• Premium grade 5WT shock oil for consistent suspension damping along a wide temperature range
• Nitrogen charged monotube design with
• Remote reservoirs maintain cooler operating temperatures during extended off-road use and allow for longer suspension travel
• One-piece digressive piston design with vehicle specific valving for unsurpassed performance and ride quality on and off-road
• 7/8″ diameter induction hardened, chrome plated shock shaft
• Polyurethane bushings and forged steel mounting stems for OE factory type fitment
• 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
• Fully rebuildable and retunable
