ICON 61804EP 3.0 Series Rear Shocks CDEV IIC 0-3" for 2017-2026 Super Duty 4WD

Vehicle Fitment

• 2017-2026 Ford F-250 Super Duty (4WD, All Cab Styles, All Engines) - 0-3" rear lift range
• 2017-2026 Ford F-350 Super Duty (4WD, Crew Cab, SuperCab, Regular Cab - Non Cab & Chassis) - 0-3" rear lift range

Fitment Notes

• 4WD models only - does not fit 2WD Super Duty
• Does NOT fit F-350 or F-450 cab & chassis models
• Does NOT fit F-450 Super Duty in any configuration - these are F-250/F-350 only
• Compatible with 0-3" of rear lift over stock
• Offset upper eyelet design allows direct fitment into factory rear shock mount locations - no modification required
• Requires installation of applicable ICON IIC Install Kit and ICON CDEV front shocks for full system operation - sold separately
• ICON Intelligent Control (IIC) app requires an iOS device
• OEM wheels and tires fit with these shocks installed
• Shocks are fully serviceable and rebuildable

Features

• ICON Compression Damping Electronic Valve (CDEV) is an infinitely variable electronically controlled valve that meters oil flow to regulate compression damping - reacts in under 40ms for near-instantaneous terrain response
• ICON Intelligent Control (IIC) uses onboard G-force sensors and gyroscope, processing data over 1,000 times per second, to automatically predict terrain and adjust CDEV damping at each shock without driver input
• ICON's internal Bump Zone increases damping by 20% as the shock approaches full compression - preventing harsh bottom-outs under high-velocity impacts
• 3.0" body diameter delivers 50% more piston surface area than ICON's 2.5 Series shocks for superior stability and vehicle control under extreme off-road demands
• Increased internal oil volume and larger external surface area versus 2.5 Series shocks provide superior heat dissipation and sustained fade resistance
• Offset upper eyelet engineering allows direct bolt-in fitment to factory rear shock mounts
• Cerakoted steel cylinders offer excellent corrosion resistance for demanding work and off-road environments
• One-piece linear compression/digressive rebound piston design with vehicle-specific valving; 100% rebuildable and re-tunable

Product Description

The ICON 61804EP is a vehicle-specific V.S. 3.0 Series rear remote reservoir shock pair with CDEV, engineered for the 2017-2026 Ford F-250/F-350 Super Duty (4WD, non-cab & chassis). These are the rear counterpart to the 61802EP front shocks and are designed to work as a complete CDEV-equipped system when paired with the appropriate ICON front shocks and IIC Install Kit. The 3.0" body delivers 50% more piston surface area than ICON's 2.5 Series, combined with greater internal oil volume and a piggyback remote reservoir for dramatically superior heat dissipation and fade resistance during sustained hard use. An integrated internal Bump Zone adds 20% more damping force as the shock nears full compression - protecting against harsh bottom-outs under high-velocity impacts on rough terrain.

The offset upper eyelet is engineered specifically to bolt directly into the factory rear shock mounts with no modification required. Like the front 61802EP, CDEV damping responds in under 40 milliseconds to commands from the IIC computer, which processes chassis G-force and gyroscope data at over 1,000 readings per second to automatically adapt to terrain changes in real time. The IIC iOS app provides full manual control via drive modes, custom presets, and data logging. Full system operation requires a compatible ICON IIC Install Kit and CDEV front shocks - sold separately. Note: these shocks do not fit F-350 or F-450 cab & chassis models, and are not compatible with 2WD Super Duty.
