ICON Vehicle Dynamics V.S. 2.5 Series internal reservoir front coilover shocks are an incredible upgrade for the front end of the 2010-2023 Toyota 4Runner, 2010-2014 Toyota FJ Cruiser, and 2010-2023 Lexus GX460. These adjustable coilovers allow up to 0-3.5” of lift height adjustability, allowing the use of larger, more aggressive wheel and tire combinations. ICON’s Vehicle-specific shock length and valving along with the larger 2.5” shock body and increased piston area over stock components yield the maximum travel possible, while still being compatible with the vehicle’s stock front upper control arms, along with superior ride quality and suspension performance both on- and off-road. Remote reservoirs greatly increase shock oil volume and heat dissipation surface area to resist overheating and cavitation under hard use, which can lead to damper fade. ICON's exclusive Compression Damping Control Valves are included for precisely dialing in your suspension performance. CDCV controls fluid flow under compression, allowing you to achieve the perfect tune whether driving on the street, slow-crawling through the rocks or mobbing across the desert at full throttle. When paired with ICON 2.0 or 2.5 Aluminum Series rear shock absorbers vehicle control will be balanced front to rear, resulting in the best overall driving experience for your Toyota 4Runner, FJ Cruiser or Lexus GX460.
