ICON K53123 Stage 3 S2 Secondary Shock Upgrade System Toyota 4Runner/FJ Cruiser

The ICON Vehicle Dynamics S2 Secondary Shock System redefines the off-road capability of the 2010-UP Toyota 4Runner and 2010-2014 FJ Cruiser by allowing for the installation of a secondary shock to an existing ICON coilover setup. The addition of a secondary 2.5 Aluminum Series or Omega Bypass shock means rougher terrain and larger off-road obstacles can be overcome with confidence as the damping ability of the vehicle's suspension is effectively doubled. As opposed to overly complicated and expensive long travel kits, the ICON S2 System is an affordable upgrade that drastically increases off-road performance, is easy to install, and has a modular design that allows 4Runner/FJ Cruiser owners to upgrade in steps or all at once.
