A wrench suspension rack assembly has a suspension base including two spaced protrusions on a side thereof and a wrench support rack for holding a plurality of tools. The wrench support rack includes a first side and a second side. Two spaced through-holes extend from the first side to the second side of the wrench support rack. The protrusions of the suspension base are respectively extended through the through-holes to thereby allow removable attachment of the wrench support rack to the suspension base.
