Ford F-150 Tremor Coilover Suspension Kit - Front - ICON - 2.5 Series VS IR Adjustable - `21-`24. These ICON 2.5 Series VS IR front coilovers are a direct-fit, performance-focused upgrade for 2021–2024 F-150 Tremor and compatible 4WD F-150s using ICON’s Front Knuckle Kit.

Built with a larger 2.5" shock body and vehicle-specific valving, this coilover kit increases damping capacity and wheel travel while providing a tuned, controlled ride on and off-road. The kit is application-specific for Tremor or F-150 models with ICON knuckles to maximize travel and lift height range. Components are serviceable and CNC-machined from 6061 aluminum with corrosion-resistant CAD plating. Installation is 100% bolt-on—no drilling or welding—and the shocks include internal nitrogen reservoirs for consistent performance under hard use.
