ICON Vehicle Dynamics 2014-2020 FORD EXPEDITION 4WD .75-2.25" STAGE 2 SUSPENSION SYSTEM W BILLET UCA K93302

Like any application that makes its way into ICON’s research and development department, the Ford Expedition was examined thoroughly in stock form in an attempt to find where the OE components were limiting performance or could be improved upon. After hours of in-house R&D and thousands of miles of real-world testing a collection of ICON components including front and rear coilovers and upper control arms were organized into two staged suspension systems that each delivers a unique level of performance to the Expedition. A remarkable level of performance is established with the 2.5 Series remote reservoir CDC Valve shocks included in ICON’s Stage 1 system, and only improves with the addition of upper control arms (tubular steel or billet aluminum) in the Stage 2 systems. These systems drastically increase the vehicle’s ride quality, reduce body roll, maximize wheel travel, and provide a lift height range of .75-2.25” to allow for the fitment of larger, more aggressive wheel and tire combinations. A bolt-on design also makes for an easy install with the ability for the vehicle to be returned to stock if needed.;This system features upper control arms with ICON's patented 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 greasable 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.
