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

When you're looking to get the most out of your 2011-2019 GM HD truck, both on and off the pavement, this ICON Vehicle Dynamics system is a solid choice. What you get in this kit are ICON's 2.5 Series Vehicle Specific (V.S.) shocks, complete with remote reservoirs and the CDCV (Compression Damping Control Valve) adjustment feature, along with a set of ICON's tubular upper control arms. These aren't just any shocks; they're built with a 6061-billet aluminum manifold that creates an internal 'Bump Zone' to add 20% more damping force as the suspension compresses, helping to prevent harsh bottom-outs. Plus, the CDCV lets you dial in 10 levels of compression damping with a simple knob turn, so you can tune the ride for different conditions.

The included upper control arms are constructed from strong, CNC-bent 1026 DOM steel tubing and finished with a semi-gloss black powder coat for durability and corrosion resistance. They feature ICON's unique Delta Joint, which is a heavy-duty, high-angle ball joint designed to offer the articulation of a uniball with the robustness and weather resistance needed for daily driving. This joint has a zinc-plated housing and a grease seal to keep out contaminants, and its metal-on-metal construction with a greaseable design means it's built to last and operate quietly. These control arms also include built-in caster correction for proper alignment and are designed to work with the shocks to nearly double your vehicle's wheel travel, leading to a much more capable and comfortable ride.

This system is designed to give your truck a 0-2 inch lift, and all the shocks are 100% rebuildable and revalveable, meaning you can service them yourself or have them tuned for future modifications. The shocks use premium 5WT shock oil to maintain consistent damping across a wide temperature range, and the remote reservoir design helps dissipate heat to reduce shock fade during hard use.
