Product Details

When you're looking to lift your 2011-2019 GM HD truck between 0 and 2 inches, this ICON system gives you a complete package. You get a set of ICON 2.5 Internal Reservoir (IR) Series shock absorbers and a pair of ICON tubular upper control arms. This system is designed to work together, providing a significant upgrade in both on-road comfort and off-road capability.

The heart of this upgrade is ICON's patented Delta Joint, found on the upper control arms. It's a heavy-duty ball joint designed to offer the articulation of a uniball but with better protection from the elements. The zinc-plated housing and tough grease seal help keep dirt and moisture out, while the metal-on-metal construction and greaseable design mean it's built to last and operate quietly. These control arms are made from CNC-bent 1026 DOM steel tubing and feature built-in caster correction to help ensure proper alignment and confident handling. The larger 2.5-inch diameter shocks offer improved heat dissipation and ride quality compared to smaller shocks, and they're fully rebuildable and revalveable, meaning you can tune them to your specific needs.

This kit is sold as a complete system because ICON found that the upper control arms perform best when paired with their shocks, allowing for nearly 50% increased wheel travel. The shocks themselves use a one-piece digressive piston with vehicle-specific valving, premium shock oil, and a nitrogen-charged monotube design with an internal reservoir for consistent performance. All the CNC-machined aluminum components and the black semi-gloss powder coat finish on the steel parts ensure durability and corrosion resistance for years to come.
