ICON Vehicle Dynamics V.S. Series 2.5" coil-over shocks are an incredible upgrade for the front end of 2009-2013 Ford F-150 4WD trucks equipped with a 6" lift subframe lift kit. ICON's Vehicle-specific valving provide a sport tuned feel on and off-road while lift height adjustability allows the fine tuning of the vehicle's ride height. Their full-length design eliminates the need for top-load coilover spacers that are commonly used with factory length coilovers for these taller lift kits. The larger 2.5" shock body and increased piston area over stock components provides improved damping ability and outstanding ride characteristics across varying types of terrain. When paired with ICON rear 2.0 Aluminum Series or 2.5 Series shocks vehicle control will be balanced front to rear, resulting in the best overall driving experience for your F-150 truck.
