Are you looking to maximize the performance and ride quality of your GM truck? The ICON Stage 1 Suspension System delivers a major upgrade in ride quality, control, and front-end performance while keeping things simple and reliable. From the factory, these trucks are stiff, harsh, and limited in suspension travel, especially when you start pushing them off-road or running heavier setups. This system fixes that by replacing weak points with properly tuned shocks and upgraded geometry components, giving you a smoother on-road ride and far more control when the terrain gets rough.

Built around ICON’s proven suspension, this system features aluminum-bodied shocks designed for consistent performance under heat, load, and repeated abuse. The 2.5” front shocks are specifically valved for the heavy-duty platform, delivering controlled damping that works with the truck’s high spring rate rather than fighting them, while the 2.0 rear shocks balance ride quality and stability.

The billet aluminum upper control arms are a major upgrade over factory components, featuring ICON’s Delta Joint system, which combines the strength of a ball joint with the articulation of a uniball. This design improves durability while reducing noise and long-term wear, making it ideal for trucks that see both daily driving and off-road use. The entire system is engineered as a 100% bolt-on package with no cutting or fabrication required. It uses high-quality materials and corrosion-resistant finishes to ensure long-term durability in harsh environments.
