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 along with superior ride quality and suspension performance both on- and off-road. 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.
