The ICON Vehicle Dynamics 2009-2013 Ford F150 4WD Stage 5 suspension system is the best choice for drivers looking to maximize the on and off-road potential of their trucks and will inspire confidence behind the wheel in nearly any situation. 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. This system includes vehicle-specific tuned 2.5” coilover shocks featuring a external remote reservoirs w/ CDCV 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 1.75-2.63” of lift over stock allowing the use of larger, more aggressive wheel and tire combinations. Tubular upper control arms on the F150 not only add strength and durability, but help retain factory alignment spec range increasing caster over stock. ICON 2.5 Aluminum Series Piggyback rear shocks w/ CDCV utilize a vehicle-specific valving that balances the performance of the truck from front to rear. 2.5" CDC reservoir front and rear shocks ensure optimum performance by increasing the duration of consistent damping regardless of situation, keeping the shocks at a cooler operating temperature during heavy use. ICON's CDC Valve upgrade is included in this stage front and rear for those desiring an easy way to tune the ride externally with 10 settings from soft to hard.
