ICON Stage 5 Suspension System 2-3.5" Lift 20-26 GM 2500HD/3500HD L5P

Want to unlock the absolute highest level of performance, control, and adjustability from your HD truck? The ICON Stage 5 Suspension System for GM HD trucks is built for drivers who demand more than just a better ride, it's a complete performance overhaul. This system takes everything from Stage 3 and pushes it further by adding CDCV-adjustable shocks front and rear, giving you total control over how your truck handles every situation. Whether you're daily driving, towing heavy, or pushing hard off-road, this setup lets you fine-tune the suspension to match your exact needs instead of settling for a fixed ride. With adjustable compression damping at all four corners, you can dial in a softer setup for comfort or a stiffer setup for aggressive terrain and load handling. Combined with increased wheel travel and corrected suspension geometry, this system delivers a planted, controlled feel at speed while eliminating the harshness and unpredictability of the factory suspension. It's the kind of setup that makes a heavy-duty truck feel precise, capable, and confidence-inspiring no matter how you use it. Built around ICON's premium 2.5 aluminum-bodied shocks, the Stage 5 system features remote-reservoir front shocks and piggyback rear shocks, all equipped with CDCV (Compression Damping Control Valve) adjusters for multi-level tuning. This design increases oil capacity and cooling efficiency, reducing fade and maintaining consistent damping under sustained abuse, heavy loads, and high-speed driving. The shocks are fully rebuildable and revalveable, making them a long-term performance solution rather than a disposable upgrade. The billet aluminum upper control arms feature ICON's Delta Joint system, combining the strength of a ball joint with the articulation of a uniball while remaining sealed against dirt, moisture, and corrosion. This improves durability for daily use while allowing increased suspension travel and proper alignment geometry. The entire system is engineered as a 100% bolt-on package using high-quality materials and corrosion-resistant finishes, delivering long-term reliability and top-tier performance for everything from towing and work use to aggressive off-road driving.
