A rack and pinion storage system for use in a refrigerator compartment defined by a liner includes a pair of supports attached to opposing sidewalls of the liner. First and second gear covers snap-fittingly connect first and second gear wheels to respective first and second mounting brackets extending from a storage basket, such that the gear wheels are rotatably connected to the storage basket and have equal rotational and linear motion along the respective supports. Retaining bars extending from the storage basket are held within channels defined between the bottom walls of the supports and top walls of opposing telescoping slide assemblies used to movably support a door of the compartment. Tabs extending from the supports limit the sliding movement of the storage basket. A removable divider connects to the storage basket, sectioning the basket into multiple storage compartments.
