ICON 2.0 Aluminum Series shock absorbers are the ultimate in cost effective upgrades. The 2.0 Aluminum Series shocks are a high quality upgrade for the everyday street driver and weekend warrior looking for improved on and off-road performance. 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. Like all ICON shock absorbers, 2.0 Aluminum Series shocks are 100% rebuildable and 100% revalveable. For those using their vehicle in extreme off road situations, consider the ICON 2.5 Series shocks to handle extra abuse and punishment your suspension will need to endure.
