ICON Vehicle Dynamics 2021-2023 Ford F-150 4WD suspension systems are designed with maximum performance and the serious driver in mind. ICON engineers' primary focus is to increase wheel travel and damping ability, which translates into outstanding vehicle control and ride quality both on and off-road. 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 2 system includes vehicle-specific tuned 2.5" coilover shocks featuring an internal reservoir for exceptional cooling properties and ICON-engineered coil springs for superior vehicle "feel" through the range of travel. These coilovers are also height adjustable for 3.5-4.5" of front lift over stock, allowing the use of larger, more aggressive wheel and tire combinations. Their combination with the ICON steering knuckles also allows for a 20% increase in wheel travel compared to other ICON F-150 coilover kits. Tubular Delta Joint Pro upper control arms on the F-150 not only add strength and durability, but help retain factory alignment spec range, increasing caster over stock and allow for the extra lift height this system provides. ICON 2.5 Aluminum Series piggyback reservoir rear shocks utilize a vehicle-specific valving and offer increased damping and head dissipation, balancing the performance of the truck from front to rear. ICON Multi-Rate Leaf Springs are included to allow rear spring rate and ride height customization, improve ride quality, and reduce axle wrap by eliminating the factory rear blocks. Rear ride height is kept within an acceptable range using the ICON billet aluminum 1" lowering shackles. The ICON Vehicle Dynamics 2021-2023 F-150 4WD Stage 2 suspension system is an excellent choice for those drivers looking to enhance the capabilities of their pickup on the road as well as in the dirt.
