ICON Vehicle Dynamics 78725 CDCV Shock System w/Upper Control Arms for the Chevy Silverado 2500HD/3500HD provides outstanding performance on and off-road. Included are ICON's 2.5 Series shocks, 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 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.

Also included in this kit are Icon tubular upper control arms. These arms are constructed from CNC bent 1026 DOM steel tubing for excellent strength. Featured are the amazing Delta Joints that combine the durability of a ball joint with the performance of a uni-ball. Ideal when paired with Icon coilovers to increase wheel travel which translates into better suspension performance and ride quality. Engineered with built-in caster correction for optimal alignment specs, serviceable dual stage poly bushings and a black semi-gloss powder coat finish for durability.
