There is provided a torsion shaft for the electronic power-assisted steering ('EPAS') system of a vehicle. The torsion shaft designed for the EPAS system is made up of a shaft, where a first portion of the shaft is magnetized, and a second portion of the shaft is non-magnetized. The torsion shaft further includes a torsion cap attached to the shaft. Also provided is a torsion shaft for an EPAS system made up of a discreet first shaft portion and a discreet second shaft portion operatively joined together, where the first shaft portion is magnetized, and a second shaft portion is non-magnetized. The torsion shaft further includes a torsion cap attached to the shaft. Further provided is a method for making a torsion shaft where at least two portions of a torsion shaft are provided. At least one portion is magnetized, and at least one portion is left free of magnetization. The portions are then joined.
