GMC Sierra HD Coilover Suspension Kit - ICON - 2.5 Series with Delta Joint - Black Semi-Gloss - 11–19. This complete shock and upper control arm system fits 2011–2019 GMC Sierra 2500/3500 HD trucks, supporting 0–2 in of lift for confident control on and off the road.

ICON’s tubular UCAs feature the patented Delta Joint, a heavy-duty, high-angle, greaseable ball joint that blends uniball-like articulation with daily-driver durability. A zinc-plated housing and tough seal help keep contaminants out, while 1026 DOM steel construction and a black semi-gloss powder coat add strength and corrosion resistance. Vehicle-specific V.S. 2.5 Series remote-reservoir shocks are nitrogen-charged, 100% rebuildable/revalveable, and include an internal Bump Zone that adds about 20% damping near full compression to reduce harsh bottom-outs. Built-in caster correction improves alignment, and together this system can deliver nearly 50% more front wheel travel.
