ICON Vehicle Dynamics 2010-2024 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 8 system includes vehicle-specific tuned, extended travel 2.5” coilover shocks featuring CDCV equipped remote reservoirs for exceptional cooling properties and ICON-engineered coil springs for superior vehicle “feel” through the range of travel. 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. 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. Tubular Delta Joint upper control arms not only add strength and durability, but help retain factory alignment specs, increasing caster over stock and allow proper wheel alignment at the lift height this system provides. ICON's tubular steel upper and lower links are much stronger than the OE units, feature a low maintenance multi-durometer bushing, and can be adjusted for optimum pinion angle. 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. An adjustable rear track bar is included to provide proper rear axle alignment, improve articulation, and ensure fitment on KDSS equipped 4Runners. The 2.5 Aluminum Series Omega bypass remote reservoir rear shocks’ larger diameter offers outstanding performance off-road and a smooth ride on the street 28 settings of compression and rebound adjustment.

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.
