ICON Stage 6 Suspension System 2-3.5" Lift 20-26 GM 2500HD/3500HD L5P
Want the absolute top-tier suspension setup ICON offers for your HD truck? The ICON Stage 6 Suspension System for GM heavy-duty trucks is built for drivers who want total control, maximum performance, and zero compromise. This is the full package: adjustable shocks on all four corners, combined with a complete rear leaf spring upgrade, completely transforming how your truck rides, handles, and performs in every condition. Factory suspension on these trucks is stiff, unpredictable, and underperforming, but this system fixes all of it in one shot.
With CDCV-adjustable 2.5” remote reservoir shocks front and rear, you can fine-tune compression damping to match exactly how you use your truck. Soft for daily driving, firm for towing, or aggressive for high-speed off-road. The addition of full rear leaf packs eliminates the harsh, choppy factory ride and replaces it with a more controlled, progressive feel that stays comfortable unloaded but still supports weight when needed. The result is a truck that feels planted, responsive, and confidence-inspiring whether you're hauling, hitting rough terrain, or just driving it every day.
Built around ICON’s highest-end suspension components, this system features 2.5” aluminum-bodied shocks with remote reservoirs and CDCV adjusters at all four corners, allowing on-the-fly tuning of compression damping. The remote reservoirs increase oil capacity and cooling efficiency, reducing fade and maintaining consistent performance under sustained heat, heavy loads, and aggressive driving. These shocks are fully rebuildable and revalveable, making them a long-term performance investment rather than a disposable upgrade.
The billet aluminum upper control arms utilize ICON’s Delta Joint system, combining the strength of a ball joint with the articulation of a uniball while remaining sealed for long-term durability and reduced maintenance. The rear leaf packs are a full multi-leaf replacement designed to improve ride quality by softening initial spring rate while maintaining load support, giving you better compliance, traction, and overall balance. The entire system is engineered as a complete bolt-on solution using high-quality materials and corrosion-resistant finishes, delivering maximum durability and performance for everything from daily driving and towing to high-speed off-road abuse.
