This King Shocks long-fin reservoir cylinder is specified for 4.0/4.5 RS remote reservoirs and measures 13.25 inches long with a 4.5-inch outer diameter. The finned exterior aids heat dissipation compared to a smooth cylinder, and it is offered as a direct replacement or upgrade to match the 4.0/4.5 RS family’s reservoir fitment and capacity for rebuilding external reservoir assemblies.
