ICON Vehicle Dynamics 2015-2020 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. The Stage 1 system includes vehicle-specific tuned 2.5” coilover shocks featuring an internal reservoir for exceptional cooling properties and ICON-engineered Eibach coil springs for superior vehicle “feel” through the range of travel. These coilovers are also height adjustable from 0-2.63” allowing the use of larger more aggressive wheel and tire combinations. ICON 2.0 Aluminum Series monotube rear shocks utilize a vehicle-specific valving that balances the performance of the truck from front to rear. The ICON Vehicle Dynamics 2015-2020 F-150 4WD Stage 1 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.
