ICON 71705CP: Vehicle-Specific 3.0 Rear Shocks Tuned for Your GM HD
The ICON 71705CP pairs two Vehicle Specific (V.S.) 3.0 Series remote-reservoir rear shocks with ICON's Compression Damping Control Valves (CDCV) for 2011-2026 GM 2500/3500 HD trucks running 0-2in of lift. Each shock is length- and damping-tuned specifically for this application, with 50% more piston surface area than ICON's 2.5 Series for greater stability and control at the extremes of off-road use, while the remote reservoir's 6061 billet aluminum manifold creates an internal "Bump Zone" for up to 20% additional damping force to prevent harsh bottom-outs.

Frequently Asked Questions
What is the ICON 71705CP?
The ICON 71705CP is a pair of Vehicle Specific 3.0 Series remote-reservoir rear shocks with Compression Damping Control Valves, built for 2011-2026 GM 2500/3500 HD trucks with 0-2in of lift.
What does CDCV do?
ICON's Compression Damping Control Valve lets you adjust compression damping to dial in ride quality for street driving, slow rock crawling, or high-speed off-road use.
Are these shocks rebuildable?
Yes. All ICON shocks, including the 71705CP, are 100% rebuildable and 100% revalveable.
How many shocks come in this kit?
This listing includes a pair — two rear shocks — for one vehicle.
Do I need new upper control arms to install these?
Not necessarily for the rear application; rear shock installation is typically a direct bolt-in. Front suspension kits from ICON may require upper control arms depending on lift height — confirm with ICON's fitment guide for your specific build.
What lift height are these shocks designed for?
These rear shocks are tuned for 0-2in of lift on 2011-2026 GM 2500/3500 HD trucks.
Will these fit both Chevrolet and GMC HD trucks?
Yes. They fit 2011-2026 Chevrolet Silverado 2500/3500 HD and GMC Sierra 2500/3500 HD trucks.
Does ICON offer a warranty on these shocks?
Contact ICON Vehicle Dynamics or your authorized dealer for current warranty terms on V.S. 3.0 Series shocks.

Suspension
Aftermarket suspension systems improve handling, ride quality, and ride height adjustment beyond what the factory suspension provides. From lowering springs and coilover kits for sport handling to lift kits and leveling kits for truck and SUV off-road capability, quality suspension components transform how a vehicle rides and handles. Popular Suspension Upgrades Popular suspension upgrades include coilover kits for adjustable ride height and damping, sport lowering springs for improved handling and reduced body roll, performance shock absorbers and strut assemblies, sway bar and end link upgrade kits, subframe brace kits, and complete suspension packages for lifted trucks and off-road SUVs. Alignment kits including camber bolts and camber arms are also frequently ordered after ride height changes. What is the difference between coilovers and lowering springs? Coilovers are complete shock and spring assemblies with adjustable ride height set by threading the spring perch on the shock...
