Description

Take the performance of your 2020-2022 GM Silverado/Sierra 2500HD/3500HD 4WD to new levels with the Icon 78732 0-2″ Internal Reservoir Shock System with Billet UCA from RDP. Crafted from CNC-machined 6061 billet aluminum, these components blend lightweight design with high strength. FK Rod End 3/4″ Heim joints ensure precise, smooth function throughout the full range of travel, while offering additional camber and caster adjustment for optimal alignment specifications, providing confident handling. When paired with our 2.5 series shock absorbers, the Icon upper control arms offer increased wheel travel, resulting in superior performance and ride quality for your GM HD truck.

These upper control arms feature Icon’s patented Delta Joint, a heavy-duty, high-angle ball joint that combines the durability of a ball joint with the performance characteristics of a traditional uni-ball. While the industry-standard uni-ball excels at reducing bind in the control arms, it is vulnerable to exposure to the elements in daily driving. The Delta Joint addresses this with a zinc-plated housing for corrosion resistance, a tough grease seal to protect the internal components, and a metal-on-metal construction for increased longevity and noise-free operation. The Delta Joint offers the best of both worlds, providing more robustness than a uni-ball, with greater angularity than a typical ball joint.

For compatibility, Icon now offers GM 2500HD/3500HD upper control arms only as part of a complete system with Icon shock absorbers. The included Icon Vehicle Specific (V.S.) 2.5 Series shocks are specifically designed for outstanding off-road performance and a smooth street ride. These shocks are configured with the ideal length and damping tune for each application. Like all Icon shock absorbers, the V.S. 2.5 Series shocks are 100% rebuildable and 100% re-valvable. The larger diameter and increased oil volume of the Icon 2.5 IR Series shocks offer better ride quality and improved heat dissipation compared to the standard 2.0 Aluminum Series IR shocks. For a more user-defined tuning experience, consider upgrading to the Compression Damping Control Valve (CDC Valve) shocks.
