ICON Vehicle Dynamics V.S. Series 2.5” remote reservoir coilover shocks are an incredible upgrade for the front end of the 2021-UP Ford F150 4WD. ICON’s Vehicle-specific valving provides a sport tuned feel on and off-road while offering 0-2.75" of lift height adjustability for use of larger, more aggressive wheel and tire combinations. 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. Remote reservoirs ensure optimum performance by increasing the duration of consistent damping regardless of situation, keeping the shocks at a cooler operating temperature during heavy use. When paired with ICON rear 2.0 Aluminum Series or 2.5 Aluminum Series shocks, vehicle control will be balanced front to rear resulting in the best overall driving experience for your F150.
