ICON Stage 1 Suspension system 3.0 Series 2-3.5" Lift 20-26 GM 2500HD/3500HD L5P

Want a massive jump in ride quality and performance without going all the way to a race-level setup? The ICON 3.0 Suspension System is built for drivers who want serious performance gains over standard 2.5 systems, especially under load and extended use. This setup upgrades you to ICON’s larger 3.0 shock platform, giving you increased damping control, better heat management, and more consistent performance when the truck is pushed hard, whether that’s towing, long highway runs, or rough backroads. What really separates this system is the 3.0 shocks. The larger shock bodies provide more oil volume and better cooling, resulting in less fade and greater control over time. The result is a truck that feels smoother over small bumps, stays planted at speed, and maintains control under heavy loads without beating you up on daily drives. It’s a balanced setup that delivers real-world performance, not just lift. The billet aluminum upper control arms feature ICON’s Delta Joint system, combining high strength with increased articulation while remaining sealed for long-term durability and reduced maintenance. The included rear leaf packs are a full multi-leaf replacement designed to soften initial spring rate while maintaining load support, improving ride quality, traction, and overall suspension balance. The entire system is a 100% bolt-on package with corrosion-resistant materials, built to handle daily driving, towing, and aggressive use while delivering long-term reliability and performance.
