Overview
ICON Vehicle Specific (V.S.) 2.5 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 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. If you are looking for a more user defined tune, consider looking into the Compression Damping Control Valve (CDCV) or the Omega Series bypass shocks.

Icon stage 4 tubular kit
I bought the Icon stage 4 tubular kit. Shock Surplus had it for a great price and I like their history of good customer service. The kit shipped fast and arrived with everything. I love the suspension upgrade on my 2015 Tacoma.
