GMC Sierra 2500HD Suspension Lift Kit - ICON - Stage 1 - `11-`19 is a purpose-built Stage 1 suspension system designed for 2011–2019 GM 2500HD/3500 trucks. This kit provides a 0–2" lift and includes ICON upper control arms engineered for durable performance on daily-driven and off-road vehicles.

The system centers on ICON’s patented Delta Joint upper control arms. The Delta Joint is a heavy-duty, high-angle ball joint that combines the longevity and sealing of a ball joint with the articulation benefits of a uniball. A zinc-plated housing and tough grease seal protect internal components from contaminants, while metal-on-metal construction and a greaseable design extend service life. The design minimizes binding and operates quietly, maintaining predictable steering and suspension movement under load.
