The ICON Vehicle Dynamics Stage 1 S2 Secondary Shock System redefines the off-road capability of the 2007-2021 Toyota Tundra by allowing for the installation of a secondary shock to an existing ICON coilover setup. The addition of a 2.5 Series piggyback reservoir secondary shock means rougher terrain and larger off-road obstacles can be overcome with confidence as the damping ability of the vehicle's front suspension is effectively doubled.

• As opposed to overly complicated and expensive long travel kits, the ICON S2 System is an affordable, mostly bolt-on upgrade that drastically increases off-road performance, is easy to install, and has a modular design that allows 2007-2021 Toyota Tundra owners to upgrade in steps or all at once. 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 lower shock mounts make for a straightforward install with the exceptional build quality you would expect from an ICON Vehicle Dynamics product.
