ICON Vehicle Specific (V.S.) 2.0 HD Series shock absorbers are the ultimate in cost effective upgrades, specifically tailored by ICON engineers for heavy duty applications. The V.S. 2.0 HD Series shocks are a high-quality upgrade for the everyday street driver and weekend warrior looking for improved on and off-road ride quality and performance. ICON 2.0 HD shocks feature hard anodized 6061 aluminum cylinders with increased wall thickness and taller DU bearings, significantly improving pull apart and side load strength compared to ICON 2.0 Aluminum Series shock absorbers. 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, V.S. 2.0 HD Series shocks are 100% rebuildable and 100% revalveable. For those using their vehicle in extreme off road situations, consider the ICON V.S. 2.5 Aluminum Series shocks to handle extra abuse and punishment your suspension will need to endure.
