ICON Vehicle Dynamics 2010-2023 Toyota 4Runner and 2010-2014 Toyota FJ Cruiser 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. This Stage 4 system includes vehicle-specific tuned, extended travel 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 0-3.5” of front lift over stock, allowing the use of larger, more aggressive wheel and tire combinations. Billet aluminum Delta Joint upper control arms not only add strength and durability but help retain factory alignment specs, offer on-vehicle caster/camber adjustment, and allow proper wheel alignment at the lift height this system provides. ICON billet aluminum adjustable rear lower links are made from CNC machined 6061 aluminum and anodized for corrosion resistance. These link arm kits feature PTFE-lined FK rod ends and greaseable polyurethane bushings for increased suspension articulation, reduced deflection, and on-vehicle link arm length adjustability using ICON’s double adjuster system. ICON rear coil springs deliver on-road comfort and superior off-road performance with 2” of rear lift height over stock for a level stance front to rear. The 2.5 Aluminum Series rear shocks’ larger diameter offers outstanding performance off-road and a smooth ride on the street. Remote reservoirs ensure optimum performance by increasing the duration of consistent damping, keeping the shocks at a cooler operating temperature during heavy use. They also feature a unique internal Bump Zone that creates an additional 20% of damping force to help better control hard bottom outs.
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 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.
