ICON's Vehicle Specific (V.S.) 2.5 Series coilover shocks are designed and built to give your vehicle outstanding performance off - road and a smooth ride on the street. These shocks are configured specifically for each application in both length and damping tune. Upgraded coil springs are included to better support added weight from accessories such as front bumpers and winches. These extended length versions offer increased wheel travel but also require the installation of aftermarket upper control arms in conjunction with the coilovers. Like all ICON shock absorbers, V.S. 2.5 Series shocks are 100 rebuildable and 100 revalveable.
