ICON Vehicle Dynamics 2.5 Series remote reservoir shock system with tubular upper control arms is built for 2020‑up GM HD trucks with 0–2" lift. These vehicle-specific shocks are configured in length and damping tune, are rebuildable and revalveable, and feature an internal Bump Zone for added damping near full compression. Paired tubular UCAs increase wheel travel and include built-in caster correction for improved alignment and handling.
