ICON 11-19 GM HD 0-2in 2.5 CDCV Shock System w/Upper Control Arm

To ensure compatibility, ICON is no longer offering GM 2500HD/3500HD upper control arms as individual components. Upper control arms can only be purchased in unison with ICON shock absorbers as a complete system. The included 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 of ICON's Shock Absorbers, the 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. The ICON CDC Valve is an externally adjustable valve that restricts oil flow into the reservoir which creates 10 levels of compression damping force ranges.

Reference Information

11-19 GM HD 0-2" 2.5 CDCV SHOCK SYSTEM W/ UCA

Icon's GM 2500HD/3500HD upper control arms are packaged with their shock absorbers as a complete system, ensuring compatibility and performance. Icon Vehicle Dynamics 2.5 VS/UCA shock systems contain shocks configured specifically for each application in both length and damping tune for outstanding performance off-road and a smooth ride on the street, along with Icon's Delta Joint tubular or billet control arm kits.

Icon's 2.5 VS CDCV shock systems offer Compression Damping Control Valve (CDCV) RR (remote reservoir) shocks with an externally adjustable valve that restricts oil flow into the reservoir, creating 10 levels of compression damping force ranges. The remote reservoir design improves heat dissipation to reduce shock-fade during prolonged use. And of course, they are 100 percent rebuildable and revalvable.

Icon's Delta Joint upper control arm kits provide the advantage of increased wheel travel, when paired with the shocks. The patented Delta Joint is a heavy-duty high-angle ball joint that combines the durability of a ball joint with the performance characteristics of a traditional uniball. They feature a zinc plated housing providing the first layer of corrosion resistance, while a tough grease seal keeps potentially harmful elements out of the inner workings of the joint. Metal-on-metal construction and a greaseable design increase the longevity of the Delta Joint while at the same time allowing for noise-free operation.
