description A retention assembly (102) for retaining a plurality of elements (104) in a stator slot (144) of an electric machine (100) is provided. The retention assembly (102) may include a stator wedge (164) fixedly positioned in a dovetail (166) in the stator slot (144) to retain the plurality of elements (104); a top ripple spring (168) between the plurality of elements (104) and the stator wedge (164); and at least one shim (110) positioned between the stator wedge (164) and a load bearing surface (165) of the dovetail (166). A method may include compressing the stator wedge (164) in the stator slot (144) from a first position thereof relative to the dovetail (166) of the stator slot (144), the compressing creating a gap (184B) between the stator wedge (164) and the dovetail (166). A shim (110) may be inserted in the gap (184B); the compressing released such that the shim (110) retains the stator wedge (164) in a second position that is more compressed relative to the plurality of elements (104) in the stator slot (
