What is the benefit of ICON's Delta Joint compared to a traditional uniball?

The Delta Joint combines the high-angle articulation of a uniball with the durability and element protection of a sealed ball joint. Its zinc-plated housing and grease seal help keep contaminants out, increasing longevity for daily driven applications.

What does the "Bump Zone" feature on the shocks do?

The internal "Bump Zone" creates an additional 20% of damping force as the shock approaches full compression. This helps prevent harsh bottom-outs and provides better control during high-velocity suspension compression.

Can these shocks be serviced or tuned?

Yes, all ICON 2.5 Series shocks included in this system are 100% rebuildable and revalveable. This allows for maintenance and customization of the damping characteristics to suit your driving needs.

Product Details

This ICON kit gives you everything you need to upgrade the front suspension on your 2011-2019 GM HD truck, including the 2.5 Series piggyback shocks and the upper control arms featuring ICON's unique Delta Joint. The Delta Joint is a heavy-duty ball joint designed to offer the durability and high-angle articulation of a uniball, but with better protection from the elements thanks to its sealed, zinc-plated housing and greaseable design. This means you get a robust joint that can handle tough terrain while still providing a quiet, smooth ride for daily driving.

The included 2.5 Series shocks are specifically tuned for your GM HD truck, aiming for outstanding off-road capability and a comfortable street ride. They are built with a 1026 DOM steel body and a 7/8" induction hardened, chrome plated shock shaft for strength. A nitrogen-charged monotube design with a remote reservoir helps manage heat and reduce shock fade during extended use. ICON's internal "Bump Zone" feature adds an extra 20% of damping force as the shock nears full compression, helping to prevent harsh bottom-outs at high speeds. The control arms themselves are made from CNC-bent 1026 DOM steel tubing and feature built-in caster correction for improved alignment and handling.

This complete system is designed to work together to nearly double your wheel travel when paired with compatible shock absorbers, leading to significantly improved performance and ride quality. All ICON shocks are 100% rebuildable and revalveable, so you can service them and adjust their performance to your needs over time.
