The assembly of claim 1, wherein the axis is defined by a longitudinal axis of the kingpin, and wherein tightening of the kingpin does not substantially impact the rotation of the hanger. 3. The assembly of claim 2, wherein the hanger defines therein a kingpin opening allowing the kingpin to pass through, and wherein the hanger further comprising a bearing member disposed in the kingpin opening at least partially surrounding the kingpin. 4. The assembly of claim 1, wherein at least one theoretical plane can be defined that is orthogonal to the kingpin and intersects the base plate and the hanger. 5. The assembly of claim 1, wherein when the hanger is rotated away from the resting position, the compression zone and the tension zone cooperatively urge the hanger to return to the resting position. 6. The assembly of claim 1, wherein the hanger presents a pair of opposing axle pins, wherein the pins are hardened and ground. 7. The assembly of claim 1, wherein the hanger coupling member protrudes from the mounting plate at an angle in the range of from about 15° to about 75°. 8.
