This is our entry level suspension system for the 2010-UP Toyota 4Runner and 2010-2014 FJ Cruiser. The Stage 1 system works well in most on and off-road scenarios by significantly improving factory body roll and overall driving ability. ICON 2.5 Series front coilover shocks feature a vehicle-specific tune to give your Toyota 4Runner great ride quality on or off-road, and they are adjustable from 0 to 3.5" of lift. Our rear 2.0 Aluminum Series shocks in this system are tuned to match the front 2.5 Series coilovers in every aspect, providing smooth and consistent damping performance front to rear. This system is finished off with a pair of 2" lift rear coil springs that have been engineered to further improve ride quality and handling.
