2020-2026 GM HD 3.0 RR Rear Shock Kit (ICO71705EP)

Upgrade the ride on your 2020-2026 GM HD with ICON 3.0 Series shocks. Vehicle-specific valving delivers better damping, less body roll, and a more planted feel on any surface. Remote reservoirs keep operating temps low during extended off-road sessions.

Features

• Vehicle specific design and tuning for superior shock damping and control
• 3.0" Body diameter for increased oil volume and larger piston area
• Extended travel length requires ICON Delta Joint Pro front upper control arms and provides maximum wheel travel
• ICON’s internal “Bump Zone" increases damping by 20% to provide more control as the shock approaches full compression
• Nitrogen charged monotube design with remote reservoir
• Remote reservoir design improves heat dissipation to reduce shock fade during prolonged use
• ICON's CDE Valve technology allows for in vehicle adjustment of compression damping settings and active adjustment via the ICON Intelligent Control (IIC)
• Premium grade 5WT shock oil for consistent suspension damping along a wide temperature range
• One-piece linear compression/digressive rebound 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
• Offset upper eyelet allows fitment into factory shock mounts
• 6061 aircraft grade aluminum CNC machined components

Important Notes

• Will not fit Cab & Chassis models
• Included rear shocks are compatible with 0-2" of rear lift over stock
• Shocks Are Fully Serviceable. Lift Heights Indicated Are For A Stock Equipped Vehicle.
• An iOS operated device is required to run ICON Intelligent Control app
• Also requires installation of applicable IIC kit and CDEV front shocks

Manufacturer Description

ICON Vehicle Specific (V.S.) 3.0 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. 3.0 Series shocks boast 50% more piston surface area compared to 2.5 Series shocks. This translates into increased stability and vehicle control at the extremes of off-road use, with benefits also making themselves apparent in on-road driving conditions. Increased internal oil volume and more external surface area compared to 2.5 Series shocks offer improved heat dissipation and resistance to shock fade under hard use. Like all ICON shock absorbers, V.S. 3.0 Series shocks are 100% rebuildable and 100% 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% of damping force. This additional force helps prevent harsh bottom outs and controls the suspension when compressing at high velocity. The ICON CDE Valve upgrade is included for those desiring an easy way to tune the ride electronically from inside the vehicle. 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.
