ICON: 3.5-4.5″/2.5-3″ Lift Front VS 2.5 Series Coilovers RR W/ Cdxs Pair – 2021-25 Ford F-150 4WD/Tremor

Description

ICON Vehicle Dynamics VS Series 2.5″ coilover shocks are an incredible upgrade for the front end of 2021-2025 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. Remote reservoirs greatly increase shock oil volume and heat dissipation surface area to resist overheating and cavitation under hard use, which can lead to damper fade. ICON’s exclusive Compression Damping Dual Speed (CDXS) valves are included for precisely dialing in your suspension performance. CDXS controls fluid flow under compression, with independent adjustability of high speed and low speed compression force. 10 discreet detented settings for both low and high-speed adjustment knobs allow separate adjustments for handling response and overall aggressiveness. 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.
