Overview
Take the performance of your 2011-2019 GM HD truck to new levels with the ICON Vehicle Dynamics Delta Joint tubular upper control arm kit. All ICON tubular upper control arms are constructed from CNC bent 1026 DOM steel tubing and then powder coated to a semi-gloss black finish for maximum strength and corrosion resistance. ICON upper control arms are engineered with built-in caster correction for optimal alignment specifications and confidence inspiring handling. A main benefit of ICON upper control arms is the increased wheel travel (nearly 50%) when paired with our 2.0 or 2.5 series shock absorbers, this translates into superior performance and ride quality for your 2011-2019 GM HD.
These upper control arms feature ICON's patented Delta Joint. The 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. While the industry standard uniball does a great job of allowing the control arms of a vehicle to articulate with little bind, they do have an inherent weakness that leaves more to be desired when used in a daily driven application - exposure to the elements. The Delta Joint features 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. What makes the Delta Joint unique is that it brings the best of both worlds to ICON upper control arms with features that make it more robust than a uniball, and at the same time capable of greater angularity than a typical ball joint.
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 Expert's Opinion
"We've been big fans of Icon's total suspension approach since running the CDCV kit on our Tacoma back in 2017. Icon regularly provides the most travel in their shocks and suspension systems when compared to competitors, giving more lift height, or more usable travel."
INFORMATION
Questions? We've got answers
ICON shocks are tuned for performance-first ride quality, which means you can expect a ride that feels firmer and more controlled than stock, especially on the street. They reduce body roll, brake dive, and overall vehicle movement, giving your truck a more planted and responsive feel.
Where ICON really stands out is off-road. These shocks are designed to handle higher speeds and rough terrain, so you’ll notice excellent control over bumps, whoops, and uneven surfaces, with less fade during repeated impacts. Instead of feeling soft or floaty, the suspension stays composed and predictable.
Overall, ICON shocks are a great fit if you want a sportier, more aggressive ride with strong off-road capability. They may feel firmer than some comfort-focused options, but they deliver a high level of control and confidence both on and off the pavement.
Some ICON shocks are adjustable, but it depends on the specific model and series. Many of ICON’s standard shocks come with vehicle-specific valving and no external adjusters, designed to deliver strong performance right out of the box without needing tuning.
However, ICON offers several higher-end options with adjustability. For example, shocks equipped with CDC (Compression Damping Control) valves provide multiple levels of compression adjustment via a knob, allowing you to fine-tune the ride for different terrain or driving styles.
At the top end, ICON also offers advanced systems like CDXS or CDEV, which can provide more precise manual adjustments or even electronic, real-time damping changes based on driving conditions.
In short, not all ICON shocks are adjustable, but many upgraded versions offer a wide range of tuning options—from simple knob adjustments to fully electronic control.
Click the 'Select Your Vehicle' button above the 'Add to Cart' button to make sure the shocks fit your exact vehicle. If needed, the site will send you to the right shocks for your ride. If your vehicle has been lifted, use the dropdown menu to pick the correct lift height. For example, if you have a Rough Country 6-inch lift kit, choose Front 4–6" and Rear 3–4" (the rear is usually smaller than the front). Still not sure? Our sales team is happy to help.
ICON shocks are built as rebuildable, high-performance shocks, so their lifespan is a little different than basic “replace when worn out” shocks. For vehicles that are mostly driven on the street, you can typically expect around 50,000–80,000 miles before a rebuild is recommended to keep them performing at their best.
If your truck sees frequent off-road use, heavy loads, or aggressive driving, service intervals can come sooner—sometimes significantly sooner—since heat, dirt, and repeated impacts accelerate wear.
The key thing to know is that ICON shocks are designed to be serviced, not thrown away. With proper maintenance and periodic rebuilds, they can deliver years of consistent performance and continue working well long after that initial service interval.
