ICON K53112 S2 Stage 2 Secondary Shock Upgrade System for Toyota Tacoma, 4Runner and FJ Cruiser

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 2 UPGRADE SYSTEM Recommended Aftermarket Tires: 33" x 11.50" (Larger tires may fit but fender trimming and modifications will be required.)

The ICON K53112 S2 Stage 2 Secondary Shock Upgrade System is engineered for select Toyota Tacoma, 4Runner, and FJ Cruiser applications, including 2005-2015 Toyota Tacoma, 2003-2009 Toyota 4Runner, and 2007-2009 Toyota FJ Cruiser models. This system uses the factory lower control arms and maintains the original-equipment track width while adding secondary damping for improved suspension control during demanding off-road driving. Recommended aftermarket tires are 33 inches by 11.50 inches; larger tires may require fender trimming or additional vehicle modifications.
The system combines billet aluminum shock tower adapters, fabricated shock hoops, steel skid plates with integrated shock mounts, and ICON 2.5 Aluminum Series secondary shocks. Its primarily bolt-on design supports a straightforward installation without major alterations to the vehicle frame or factory suspension components. The modular components are fully removable, allowing the system to be transferred to another compatible vehicle. The skid plates may also be installed independently to help protect the factory lower control arms from trail hazards.
The vehicle-specific tuned secondary shocks increase damping capability and oil volume for improved off-road performance, while CDC Valve technology enables quick, convenient compression damping adjustments. One-piece impact-extruded aluminum shock cylinders provide corrosion resistance and a consistent finish. The shocks are fully rebuildable and revalveable, supporting long-term serviceability and tuning flexibility. Together, these features help improve vehicle stability on pavement and suspension control over uneven terrain. This ICON upgrade system is designed for enthusiasts seeking stronger damping performance without sacrificing factory track width or requiring extensive chassis modifications.
