ICON Vehicle Specific 2.5 Aluminum Series Shock Absorbers for Chevy and GMC 2500/3500 HD

ICON Vehicle Specific (V.S.) 2.5 Aluminum 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. Like all ICON shock absorbers, V.S. 2.5 Aluminum 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. ICON's exclusive Compression Damping Control Valves are included for precisely dialing in your suspension performance. CDCV controls fluid flow under compression, allowing you to achieve the perfect tune whether driving on the street, slow-crawling through the rocks or mobbing across the desert at full throttle. ICON V.S. 2.5 Aluminum Series shocks are designed and built to give your vehicle outstanding performance off-road and a smooth ride on the street. They feature remote reservoirs and are 100% rebuildable/revalveable. APPLICATION NOTE #298: 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.

The ICON Vehicle Specific (V.S.) 2.5 Aluminum Series shocks are engineered to deliver exceptional off-road performance while maintaining a smooth and comfortable ride on paved roads. Designed specifically for 2011 Chevrolet Silverado 2500/3500 HD and GMC Sierra 2500/3500 HD models, these shocks feature a remote reservoir setup that enhances heat dissipation and reduces shock fade during extended use. The high-quality components, including impact-extruded aluminum cylinders and a nitrogen-charged monotube design, ensure durability and consistent damping performance across a variety of terrains.
The one-piece digressive piston with vehicle-specific valving provides precise control and optimal ride quality both on and off-road. ICON’s internal “Bump Zone” creates an internal damping zone that increases damping force by 20%, helping to prevent harsh bottom outs when compressing at high velocities. This feature is especially beneficial when navigating rough trails or high-speed desert runs, providing increased suspension control and driver confidence.
Equipped with ICON’s innovative Compression Damping Control Valve (CDCV) technology, these shocks offer ten levels of high-resolution compression adjustability. This allows you to fine-tune your suspension to match your driving conditions, whether you're crawling through rocks or cruising on highways, ensuring maximum comfort and stability. The shocks are designed to be 100% rebuildable and revalveable, giving you long-term reliability and the flexibility to customize performance as needed. Their extended travel length and compatibility with aftermarket control arms support maximum wheel travel, making them ideal for lifted or custom vehicles. The use of premium shock oil and high-grade materials guarantees consistent damping performance across a broad temperature range, ensuring reliability in all weather conditions.
With a robust 7/8” chrome-plated shock shaft and CNC-machined 6061 aircraft-grade aluminum components, these shocks combine strength with corrosion resistance. Their impact-extruded aluminum cylinders and bonded rubber bushings provide OE-like fitment and vibration damping, resulting in a smooth ride and enhanced durability. Suitable for vehicles with 0-3.5 inches of front lift, the ICON 2.5 Aluminum Series shocks are an excellent upgrade for off-road enthusiasts seeking improved handling, control, and ride quality.
