Description

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.

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.
