Construction & Design

The ICON Stage 4 Suspension System is built with high-quality materials and meticulous engineering to withstand the demands of both on-road and off-road driving. The 2.0 Aluminum Series shocks feature lightweight yet durable aluminum bodies that resist corrosion and dissipate heat efficiently, ensuring consistent performance under extended use. The front lower links are constructed from tubular steel, providing exceptional strength and rigidity to maintain proper suspension geometry during articulation.

Coil springs are carefully calibrated with dual and triple-rate designs to balance comfort and load capacity, adapting to varying terrain and driving conditions. Billet aluminum sway bar links add precision and durability, reducing unwanted flex and improving steering response. Adjustable track bars allow fine-tuning of axle positioning, enhancing stability and tire wear.

Installation & Fitment
