ICON S2 Stage 3 Upgrade System K53113 for 2005-2015 Toyota Tacoma, 2003-2009 4Runner and 2007-2009 FJ

The S2 Secondary Shock System utilizes the factory lower control arms and maintains OE track width while a combination of a billet aluminum shock tower adapters, fabricated shock hoops, and steel skid plates (with incorporated shock mounts) make for a straightforward install with the exceptional build quality you would expect from an ICON Vehicle Dynamics product. The system was designed to eliminate the need for any major alteration of the vehicle’s frame or any other factory suspension components, and the components are 100% removable in case the system is to be installed on another vehicle. The modular design of the S2 kit also allows for standalone installation of the skid plates, which provides the added benefit of protecting the factory lower control arms from potential trail damage that can be experienced while off-road. 2005-2015 TACOMA/20003-2009 4RUNNER/2007-2009 FJ S2 STAGE 3 UPGRADE SYSTEM Recommended Aftermarket Tires: 33" x 11.50" (Larger tires may fit but fender trimming and modifications will be required.)

The ICON S2 Stage 3 Upgrade System, part number K53113, is engineered to improve damping performance, stability, and off-road capability for select Toyota Tacoma, 4Runner, and FJ applications. The system utilizes the factory lower control arms and maintains original equipment track width, helping preserve the vehicle’s established handling characteristics while adding secondary shock support. It is designed for use with recommended aftermarket tires up to 33 inches by 11.50 inches; larger tires may require fender trimming or additional modifications.
The system combines billet aluminum shock tower adapters, fabricated shock hoops, and steel skid plates with integrated shock mounts for a durable, vehicle-specific installation. Its mostly bolt-on design avoids major alterations to the vehicle frame and factory suspension components, while the fully removable construction allows the system to be transferred to another compatible vehicle. The skid plates can also be installed independently to help protect the factory lower control arms from trail impacts and off-road hazards.
ICON 2.5 Aluminum Series secondary shocks use one-piece, impact-extruded aluminum cylinders for corrosion resistance and a consistent finish. Omega Series two-tube bypass technology provides adjustable compression and rebound damping, while vehicle-specific shock tuning increases damping control and oil volume for demanding terrain. The result is improved suspension control off-road and increased vehicle stability on-road. The shocks are fully rebuildable and revalveable, supporting long-term serviceability and performance customization. Professional installation is recommended, and fitment should be verified before ordering.
