Want serious performance gains with real-world usability without jumping all the way to race-level complexity? The ICON Stage 3 Suspension System with 3.0 Shocks is built for drivers who demand more control, comfort, and consistency from their truck. This system upgrades you to ICON’s larger 3.0 shock platform with compression adjustability while also replacing the factory rear leaf springs, fixing both damping performance and ride quality in one complete package.
The result is a truck that feels completely different. You get a smoother ride over small bumps, better control at speed, and the ability to fine-tune how the suspension reacts based on your driving style or load. Whether you're towing, daily driving, or pushing rough terrain, this setup delivers a balanced, planted feel without the harshness or unpredictability of the factory suspension. It’s the sweet spot for guys who want high-end performance without going full race setup.
Built around ICON’s 3.0 aluminum-bodied shocks, this system is designed for increased oil capacity and superior heat dissipation compared to standard 2.5 shocks, allowing for more consistent damping under load and extended use. The shocks feature remote reservoirs and CDCV (Compression Damping Control Valve) adjusters, giving you multiple levels of compression tuning so you can dial in ride quality for comfort, towing, or aggressive driving.
The billet aluminum upper control arms utilize ICON’s Delta Joint system, combining the durability of a ball joint with the articulation of a uniball while remaining sealed against dirt and moisture for long-term reliability. The rear leaf pack is a full multi-leaf replacement designed to soften initial spring rate while maintaining load support, improving small bump compliance and overall ride balance. Together, this system is engineered as a complete bolt-on solution using high-quality, corrosion-resistant materials, delivering long-term durability and consistent performance in everything from daily driving to heavy-duty use.
