Description

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.

About ICON Vehicle Dynamics

ICON Vehicle Dynamics is a premiere performance suspension manufacturer specializing in aftermarket suspension components for trucks, SUVs and off road suspension development. The companys business is customer-driven, technology-influenced, engineering-oriented and focuses on world-class manufacturing processes and techniques. Led by head engineer and SCORE champion driver Dylan Evans, ICON Vehicle Dynamics has the unique qualities to design and build the highest quality suspension components and test them in both real world applications as well as race conditions.

ICON is often asked how they develop such revolutionary performance suspension systems. The answer might surprise you. Their engineers actually start by determining a desired outcome of the vehicle they are working on. By studying forces and their effect on the vehicle in motion (Vehicle Dynamics) they are able to determine what improvements can be made. They determine how they can improve drivability of the vehicle, how to improve the handling characteristics and what changes can be made to improve the vehicle in real world situations. The end result of all this study is the highest quality and performing suspension products in the world. What also sets ICON products apart is our incredible commitment of time and energy dedicated to both ride development and testing. From vehicle dynamic theory to our years of experience and involvement in off road racing, rock crawling and just about anything you can do with a vehicle on or off the road. ICON engineers are in control and the driving force of the entire product line and manufacturing processes. This is made possible because all of their laser cutting, metal forming, CNC machining, welding and assembly is done in house.
