Icon Vehicle Dynamics 71707XP 2.5 VS Remote Reservoir CDXS Rear Reservoir Adjustable Shock Lift 0-3.5" Chevrolet Silverado/GMC Sierra 2500/3500 AT4/AT4X/ZR2 11-26 Pair

ICON V.S. 2.5 Aluminum Series

Vehicle-specific 2.5" aluminum shocks engineered for outstanding off-road performance and a smooth on-road ride. Each shock is tuned and configured for the specific application in both length and damping. These shocks are 100% rebuildable and 100% revalveable. For piggyback and select remote reservoir applications, a 6061 billet aluminum manifold creates an internal "Bump Zone" that increases damping by 20% to help prevent harsh bottom outs and control high-velocity compression. ICON Compression Damping Dual Speed (CDXS) valves provide independent high-speed and low-speed compression adjustment with 10 detented settings for precise suspension tuning.

Key Features

• Compatibility: Supports 0–3.5" of front lift over stock on most applications.
• Extended travel: Requires aftermarket front upper control arms and provides maximum wheel travel.
• Internal Bump Zone: Increases damping by 20% to control compression near full travel.
• Design: Nitrogen-charged monotube with remote reservoir for improved heat dissipation and reduced shock fade.
• Adjustability: ICON CDXS for independent high-speed and low-speed compression control.
• Fluid: Premium grade 5WT shock oil for consistent damping across a wide temperature range.
• Piston: One-piece digressive piston with vehicle-specific valving for superior on- and off-road ride quality.
• Shaft: 7/8" diameter induction-hardened, chrome-plated shock shaft.
• Mounting: Press-in, bonded rubber bushing/bar pin assembly to damp road vibration and provide OE-type fitment.
• Construction: 6061 aircraft-grade aluminum CNC-machined components and one-piece hard-anodized, impact-extruded aluminum cylinders for corrosion resistance and consistent finish.
• Serviceability: 100% rebuildable and 100% revalveable.

Notes

• These systems are to be used with aftermarket upper control arms only.
• Shocks are fully serviceable. Lift heights indicated are for a stock-equipped vehicle.
• Compatible with 0–3.5" of front lift on most Chevrolet Silverado 2500/3500 HD and GMC Sierra 2500/3500 HD submodels. Compatible with 0–2" of front lift on Chevrolet Silverado 2500 ZR2 and GMC Sierra 2500 AT4X.
