GMC Sierra 2500HD Suspension Lift Kit - ICON - Stage 3 - `11-`19 is a Stage 3 suspension system engineered for 2011–2019 GMC Sierra 2500HD/3500 trucks. It provides a 0–2" lift and includes ICON upper control arms featuring the patented Delta Joint.

This kit centers on ICON's Delta Joint — a heavy-duty, high-angle ball joint that combines the durability of a ball joint with the articulation characteristics of a uniball. The joint uses a zinc-plated housing for corrosion resistance and a tough grease seal to keep contaminants out. Metal-on-metal construction and a greasable design extend service life while reducing noise in daily-driven applications. The Stage 3 package is intended for owners who want improved control arm articulation and a robust, serviceable front-end solution for 2011–2019 GM 2500HD/3500 platforms. Ships in multiple boxes.
