Icon 4Runner 0-3.5″ Suspension System – Stage 4 Tubular UCA Icon

Icon 5th Gen 4Runner 0-3.5″ Suspension System – Stage 4 Tubular UCA – 2010-Current

Any vehicle, much less an off-road vehicle, must have a reliable and sturdy suspension system. It can improve how well your car handles rocky terrain without harming it. We are therefore delighted to present the Icon suspension system made to fit the 4Runner models. 

The Icon 5th Gen 4Runner suspension kit was constructed out of durable CNC machined 6061 aircraft grade aluminum and has a corrosion-resistant CAD plated coilover shock body with 7/8″ shaft. This is also a bolt-on system meaning that no cutting or welding is needed for installation.

The vehicle’s on and off-road performance is significantly improved with ICON’s Stage 4 suspension system for the 5th Gen Toyota 4Runner. The Stage 3 setup’s components, such as the 2.5 Series coilover shocks with extended travel, the ICON tubular Delta Joint upper control arm kit, the 2″ rear coil springs, and the tubular rear lower link arm kit, are still present in this system, but 2.5 Aluminum Series Remote Reservoir rear shocks have been added for front-to-rear damping balance.

The rear of the car can operate harder for longer periods of time without observable “fade” thanks to the remote reservoir design’s higher shock oil capacity and improved cooling. The 2.5 Aluminum Series Remote Reservoir rear shocks are also equipped with ICON’s “Bump Zone” technology, which greatly improves damping capability in the final 2″ of compression travel to reduce severe bottom-out sensations and provide a much more controllable ride quality on a variety of terrain.

ICON’s lower links are made of tubular steel, which makes them stronger than OE parts. They also have a multi-durometer bushing that requires less maintenance and can be adjusted for the best pinion angle. Additionally, these linkages have been created to offer the proper roll steer geometry for the greatest on and off-road performance.

Upper control arms with the proprietary ICON Delta Joint are a component of this system. The Delta Joint is a heavy-duty, high-angle ball joint that combines typical uniball performance with the durability of a ball joint. The industry standard uniball does an excellent job of enabling a vehicle’s control arms to articulate with minimum binding, but it has an inherent flaw that leaves more to be desired when employed in a daily driving application: exposure to the environment.

The Delta Joint has a zinc-plated housing that offers the first line of defense against corrosion, and a robust grease seal keeps potentially dangerous materials out of the joint’s interior workings. Its durability is increased by its metal-on-metal construction and greaseable design, both of which enable noiseless operation.

The Delta Joint is special because it gives ICON upper control arms the best of both worlds thanks to qualities that make it more durable than a uniball and, at the same time, capable of greater angularity than a normal ball joint.

Upper Control Arm 

Whenever you are changing your vehicle’s geometry and upgrading it with a suspension kit, especially on 4WD vehicles, you absolutely need an upper control arm. The UCA is there to correct alignment and inherent clearance issues that arise when you lift or modify the suspension of your 4WD. Upper control arms can be found on independent front suspension (IFS) vehicles and they connect the top of the spindle to the frame.

The UCA is not a load-bearing piece of an IFS suspension, however, it does serve the purpose of guiding your spindle in a pre-determined motion when your suspension cycles up or down. Said load is handled by the lower control arm, which connects to the lower portion of the spindle.
