A wing flex assembly for a frame system of an agricultural implement that includes inner and outer tubes. The outer tube, to which tools of the implement are attached, is slidingly displaceable along the inner tube as the inner tube is downwardly pivotally displaced with a downward flex of a wing frame. A first tool of a center frame can be separated from an adjacent second tool of the wing frame that is attached to the outer tube by a first distance when the outer tube is at a retracted position, and a second distance when the outer tube is slidingly displaced in response to the downward pivotal displacement of the inner tube, the first distance being about equal to the second distance. The wing flex assembly can also prevent contact between the first and second tools when the inner tube is pivotally displaced in an upward direction.
