An end attachment assembly for a twisted rope torsion bar includes an anchor nut having a spiral bore cooperatively receiving and positively engaging the outer contour of the torsion bar. The grooves of the spiral hole promote holding contact between the anchor nut and the torsion bar but allow relative movement to minimize stress build-up; a lightweight glass fiber/epoxy composite material is preferred for fabrication of the torsion bar. A thrust stop is provided to prevent the nut from being forced off the end of the torsion bar in response to axial forces created by the sliding movement of the torsion bar within the spiral bore. The thrust stop is made of elastomeric material and is integrally molded onto the end of the torsion bar. The thrust stop has a tapered body to cooperatively engage with a tapered opening in the anchor nut. Advantageously, the thrust stop tightly engages the anchor nut to limit axial motion of the anchor nut and convert a portion of the thrust into compressive forces promoting tighter contact between the thrust stop and the torsion bar under increased torque.
