OVERVIEW ICON’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. With a truly vehicle-specific design, these shocks are configured specifically for each application in both length and damping tune. Featuring one-piece impact extruded aluminum cylinders, these 2.5 Aluminum Series shocks offer lighter weight, improved corrosion resistance, and a more uniform finish than traditional plated steel cylinders. Like all ICON shock absorbers, these 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-out conditions and controls the suspension effectively when compressing at high velocity. If you are looking for a more user-defined tune, consider looking into the Compression Damping Control Valve (CDCV) shocks.
