Upgrade your 2019-2023 GM Silverado/Sierra 1500 (Rear Lifted 0-2") with the Icon 77703P 2.5 VS Piggyback Shock Absorber (Pair) from SDS. 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% re-valvable. 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% 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) shocks.
