ICON V.S. Series 2.5 IR Front Coilover Kit for 2021-2025 Ford F-150 (91723)

Fits 2021-2025 Ford F-150 including XL, XLT, STX, Lariat, King Ranch, Platinum, SSV, Police Responder, and Tremor models.

The ICON Vehicle Dynamics V.S. Series 2.5 IR (Internal Reservoir) front coilover kit is a premium suspension upgrade designed to optimize the performance of 2021-2025 Ford F-150 4WD trucks. Engineered specifically for the Tremor or standard F-150 models equipped with ICON’s Front Knuckle Kit, these coilovers provide increased wheel travel and a versatile lift height range. The larger 2.5-inch shock bodies offer significantly more oil volume and piston surface area compared to stock components, resulting in superior damping control and heat dissipation across aggressive off-road terrain.

Each coilover is built with a corrosion-resistant CAD-plated shock body and a 7/8-inch induction-hardened chrome-plated shaft. The internal nitrogen reservoir design maintains consistent performance under heavy use by preventing oil aeration. For durability, ICON uses 6061 aircraft-grade aluminum CNC-machined components and FK rod end bearings to minimize deflection and extend service life. This kit is a 100% bolt-on application, requiring no drilling, cutting, or welding for installation.
