Description

ICON Vehicle Dynamics V.S. Series 2.5” coilover shocks are an incredible upgrade for the front end of 2021-2026 Ford F-150 Tremor and F-150 4WD trucks equipped with ICON's Front Knuckle Kit. These coilovers feature an application specific length for F-150 Tremor or other F-150 sub-models equipped with ICON’s Front Knuckle Kit, allowing the most wheel travel possible as well as a taller lift height range than other ICON coilover options. ICON’s Vehicle-specific valving provides a sport tuned feel on and off-road while 2.5-3” of lift height adjustability on F-150 Tremor or 3.5-4.5” of lift height adjustability on other F-150 sub-models allow the 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. 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 F-150.
