The ICON Vehicle Dynamics Coilover Reservoir Upgrade Kit is used to upgrade a set of ICON internal reservoir coilovers from a 2007-2021 Toyota Tundra or 2008-2022 Toyota Sequoia to remote reservoirs during a shock rebuild. The addition of remote reservoirs will greatly increase shock oil volume and heat dissipation surface area to resist overheating and cavitation under hard use, which can lead to damper fade. This kit includes all required components for the reservoir upgrade including top caps, reservoirs, reservoir brackets, hoses, and seal kits.
