ICON’s Vehicle-specific shock length and valving along with the larger 2.5” shock body and increased piston area over stock yield the maximum travel possible along with superior ride quality and suspension performance both on- and off-road.
Compression Damping Electronic Valve (CDEV) is an electronically controlled valve that meters the flow of oil to regulate the amount of damping force that is created by the shock when compressed. This infinitely variable valve can react in less than 40ms and has the ability to make extremely precise adjustments for varying terrain. CDEV’s hydraulic circuits are also custom tailored per application to create the highest resolution and dynamic range allowable for each specific vehicle. Powered by ICON Intelligent Control and proprietary ICON mobile app, the system uses information from the onboard G-force sensor and Gyroscope to perform calculations based on algorithms and user-defined settings to predict terrain and adjust shock settings via the CDEV accordingly.
- ICON's CDE Valve technology allows for in vehicle adjustment of compression damping settings and active adjustment via the ICON Intelligent Control (IIC)
- 6061 Aircraft grade aluminum CNC machined components
- Corrosion resistant CAD plated shock bodies with 7/8" induction hardened, chrome plated shafts
- FK rod end bearings for extended longevity and minimal deflection
- Bolt-on kit - no cutting or welding necessary for installation
- 100% Rebuildable
- 100% Revalveable
- Increased wheel travel and ride quality over stock
- Vehicle specific tuned for superior shock damping and control
- Adjustable for 0-3.5" of lift height over stock
- ICON engineered coil springs with 700 lbs/in spring rate
- External reservoirs to attain cooler operating temperatures during extended off-road use
Information:
APPLICATION NOTE #55: Shocks are fully serviceable. Lift heights indicated are for a stock equipped vehicle.
