Description

Want a massive jump in ride quality and performance without going all the way to a race-level setup? The ICON 3.0 Suspension System is built for drivers who want serious performance gains over standard 2.5 systems, especially under load and extended use. This setup upgrades you to ICON’s larger 3.0 shock platform, giving you increased damping control, better heat management, and more consistent performance when the truck is pushed hard, whether that’s towing, long highway runs, or rough backroads. What really separates this system is the 3.0 shocks. The larger shock bodies provide more oil volume and better cooling, resulting in less fade and greater control over time. The result is a truck that feels smoother over small bumps, stays planted at speed, and maintains control under heavy loads without beating you up on daily drives. It’s a balanced setup that delivers real-world performance, not just lift. The billet aluminum upper control arms feature ICON’s Delta Joint system, combining high strength with increased articulation while remaining sealed for long-term durability and reduced maintenance. The included rear leaf packs are a full multi-leaf replacement designed to soften initial spring rate while maintaining load support, improving ride quality, traction, and overall suspension balance. The entire system is a 100% bolt-on package with corrosion-resistant materials, built to handle daily driving, towing, and aggressive use while delivering long-term reliability and performance.

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.
