Construction & Design

The ICON Stage 4 Suspension System is engineered for durability and long-lasting performance. Its dual rate progressive wound springs feature a softer initial rate for comfortable daily driving and a firmer secondary rate that activates during compression to prevent harsh bottoming out on rough trails. This adaptive spring design ensures a versatile suspension that performs well in diverse driving conditions.

ICON’s 2.5 Aluminum Series Reservoir shocks incorporate remote reservoirs that increase fluid capacity and improve heat dissipation. This design maintains consistent damping performance even during extended off-road use, while the lightweight aluminum construction enhances corrosion resistance and reduces unsprung weight for better handling and longevity.
