ICON Vehicle Dynamics V.S. 2.5 Aluminum Series remote reservoir shocks are engineered to provide consistent damping performance for heavy-duty GM trucks whether on technical trails or high-speed washboards. These nitrogen-charged monotube shocks feature a 2.5-inch diameter hard-anodized aluminum body that provides superior heat dissipation compared to steel, significantly reducing shock fade during prolonged use. The remote reservoir design further increases oil capacity and cooling surface area, ensuring the 5WT premium shock oil remains stable under high-demand cycles.

A standout feature of this application is ICON’s internal “Bump Zone,” which utilizes a 6061 billet aluminum manifold to create an additional 20% of damping force as the shock reaches full compression. This helps prevent harsh bottom-outs and maintains chassis control during high-velocity impacts. Each shock is custom-valved with a one-piece digressive piston for a compliant street ride that firms up quickly for off-road stability.
