04-08 Ford F150 Suspension System-Stage 4

The ICON Vehicle Dynamics 2004-2008 Ford F150 Stage 4 suspension system is the best choice for drivers looking to maximize the on and offroad 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 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. Optional Tubular or Billet 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 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 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 for those desiring an easy way to tune the ride externally with 10 settings from soft to hard.

DELTA JOINT OVERVIEW:

 This system features upper control arms with ICON's patent pending Delta Joint. The Delta Joint is a heavy-duty high angle ball joint that combines the durability of a ball joint with the performance characteristics of a traditional uniball. While the industry standard uniball does a great job of allowing the control arms of a vehicle to articulate with little bind, they do have an inherent weakness that leaves more to be desired when used in a daily driven application - exposure to the elements. The Delta Joint features a zinc plated housing providing the first layer of corrosion resistance, while a tough grease seal keeps potentially harmful elements out of the inner workings of the joint. Metal on metal construction and a greaseable design increase the longevity of the Delta Joint while at the same time allowing for noise-free operation. What makes the Delta Joint unique is that it brings the best of both worlds to ICON upper control arms with features that make it more robust than a uniball, and at the same time capable of greater angularity than a typical ball joint.

CDC VALVE FEATURES:

The ICON CDC Valve is an externally adjustable valve that restricts oil flow into the reservoir which creates 10 levels of compression damping force ranges. If you are looking for a more user defined tune, consider looking into the Omega Series bypass shocks.

• CDC Valve shocks are application specific tuned like all ICON shocks
• Internally calibrated per application based on motion ratio, shaft diameter, and vehicle weights
• 10 detented stops and large adjuster knob provide easy-to-feel adjustments
• Allows the end user to optimize vehicle's ride specific to his/her liking on all types of terrain
• Clearly engraved knob for direct reading of current setting

KEY FEATURES:

• Increased wheel travel and ride quality over stock with no change in towing capacity
• Vehicle specific tuned front and rear shocks for superior damping and vehicle control
• Adjustable coilovers from 0-2.63" of lift height
• ICON CDCV equipped rear shocks for full compression tuneability of your shocks
• Billet upper control arms for added strength, durability, adjustability, and improved alignment geometry
