The ICON Stage 2 Jeep JK 4.5" suspension system includes dual-rate coil springs, track bar drop brackets, high-steering components, bump stop spacers, rear brake lines, rear sway bar links, complete set of front and rear links, and 2.0 Aluminum Series remote reservoir shocks. Tested and tuned, the ICON JK Stage 2 suspension system offers stability and drivability over a wide range of off-road terrains, while keeping a smooth on road feel for every day driving. Adding the remote reservoirs to the 2.0 shocks keeps them at a cooler operating temperature during heavy use for more consistent shock damping and overall performance. Installing this kit allows proper clearance for 35" tall tires with no modifications and 37" tires with aftermarket high clearance fenders.
