ICON 21-24 Ford F-150 4WD 2.5 Series Stage 4 Tubular CDXS Suspension System w/ Leaf Pack

K93144TLD Overview
ICON Vehicle Dynamics 2021-2024 Ford F-150 4WD suspension systems are designed with maximum performance and the serious driver in mind. ICON's primary focus is to increase wheel travel and damping ability, which translates into outstanding vehicle control and ride quality. To achieve this, these systems include high-strength CNC machined ductile iron steering knuckles that replicate the suspension geometry of the F-150 Tremor and are effectively a Tremor “conversion” for your F-150 4WD. This Stage 4 system includes vehicle-specific tuned 2.5” coilover shocks featuring CDXS equipped remote reservoirs for exceptional cooling properties and ICON-engineered coil springs for superior vehicle “feel” through the range of travel. These coilovers are height adjustable for 3.5-4.5” of front lift, allowing the use of larger, more aggressive wheel and tire combos. Their combination with the ICON steering knuckles also allows for a 20% increase in wheel travel compared to other ICON F-150 kits.
The 4-link brackets, upper links, and lower links are sold separately, allowing the 4-link system to be customized for your specific Ford Super Duty year range.
